(Embodiment 1)
Fig. 1 is a configuration diagram showing an example of a display system according to embodiment 1. Fig. 2 is a schematic diagram showing an example of a relative relationship between a display device and a user's eyes.

In this embodiment, the display system 1 is a display system that changes the display in accordance with the movement of the user. For example, the display system 1 is a VR system that stereoscopically displays a VR (Virtual Reality) image showing a three-dimensional object in a virtual space, and changes the stereoscopic display in accordance with the orientation (position) of the user's head, thereby creating a sense of virtual reality for the user.

The display system 1 includes, for example, a display device 100 and a control device 200. The display device 100 and the control device 200 are configured to be capable of inputting and outputting information (signals) via a cable 300. The cable 300 includes, for example, cables such as USB (Universal Serial Bus) and HDMI (registered trademark) (High-Definition Multimedia Interface). The display device 100 and the control device 200 may be configured to be capable of inputting and outputting information via wireless communication.

The display device 100 is supplied with power from the control device 200 via the cable 300. For example, the display device 100 may have a power receiving unit to which power is supplied from the power supply unit of the control device 200 via the cable 300, and each component of the display device 100, such as the display panel 110 and the sensor 120, may be driven using power supplied from the control device 200. In this way, a battery or the like can be removed from the display device 100, and a cheaper and lighter display device 100 can be provided. Note that a battery may be provided in the mounting member 400 or the display device 100, and supplied to the display device.

The display device 100 has a display panel. The display panel is, for example, a liquid crystal display (LCD), but may also be an organic electroluminescence (EL) panel, μ-OLED, μ-LED panel, mini-LED panel, etc.

The display device 100 is fixed to the wearing member 400. The wearing member 400 includes, for example, a headset, goggles, a helmet that covers both eyes of the user, a mask, etc. The wearing member 400 is worn on the user's head. When worn, the wearing member 400 is positioned in front of the user so as to cover both eyes of the user. The wearing member 400 functions as an immersive wearing member by positioning the display device 100 fixed inside in front of both eyes of the user. The wearing member 400 may have an output unit that outputs sound signals, etc., output from the control device 200. The wearing member 400 may also have a structure that incorporates the functions of the control device 200.

In the example shown in FIG. 1, the display device 100 is shown as being slotted into the mounting member 400, but it may also be fixed to the mounting member 400. In other words, the display system may be composed of the mounting member 400, a wearable display device including the display device 100, and the control device 200.

2, the mounting member 400 has lenses 410 corresponding to both eyes of the user, for example. The lenses 410 are magnifying lenses for forming an image on the user's eyes. When the mounting member 400 is mounted on the user's head, the lenses 410 are positioned in front of the user's eyes E. The user visually recognizes the display area of the display device 100 magnified by the lenses 410. Therefore, the display device 100 needs to have high resolution in order to display an image (screen) clearly. Note that, although the present disclosure has been described with one lens as an example, the display device 100 may have multiple lenses and be positioned in a position other than in front of the eyes, for example.

The control device 200, for example, causes an image to be displayed on the display device 100. The control device 200 may be, for example, an electronic device such as a personal computer or a game device. The virtual image includes, for example, images such as computer graphic images and 360-degree live-action images. The control device 200 outputs a three-dimensional image that utilizes the parallax of the user's eyes to the display device 100. The control device 200 outputs images for the right eye and the left eye that follow the direction of the user's head to the display device 100.

FIG. 3 is a block diagram showing an example of the configuration of a display system according to the first embodiment. As shown in FIG. 3, the display device 100 includes two display panels 110, a sensor 120, an image separation circuit 150, and an interface 160.

The display device 100 is composed of two display panels 110, one of which is used as the left eye display panel 110 and the other is used as the right eye display panel 110.

Each of the two display panels 110 has a display area 111 and a display control circuit 112. The display panel 110 has a light source device (a backlight IL, described later) (not shown) that illuminates the display area 111 from behind.

In the display area 111, P ₀ ×Q ₀ pixels Pix (P ₀ in the row direction and Q ₀ in the column direction) are arranged in a two-dimensional matrix (row and column shape). In this embodiment, P ₀ =2880, Q ₀ =1700. In Fig. 3, the arrangement of the multiple pixels Pix is shown diagrammatically, and the detailed arrangement of the pixels Pix will be described later.

The display panel 110 has scanning lines extending in the Vx direction and signal lines extending in the Vy direction intersecting the Vx direction. For example, the display panel 110 has 2880 signal lines SL and 1700 scanning lines GL. In the display panel 110, pixels Pix are arranged in an area surrounded by the signal lines SL and the scanning lines GL. The pixels Pix have switching elements (TFTs: thin film transistors) connected to the signal lines SL and the scanning lines GL, and pixel electrodes connected to the switching elements. A single scanning line GL is connected to multiple pixels Pix arranged along the extension direction of the scanning lines GL. A single signal line SL is connected to multiple pixels Pix arranged along the extension direction of the signal lines SL.

Of the two display panels 110, the display area 111 of one display panel 110 is for the right eye, and the display area 111 of the other display panel 110 is for the left eye. In the first embodiment, a case will be described in which the display panel 110 has two display panels 110, one for the left eye and one for the right eye. However, the display device 100 is not limited to a structure using two display panels 110 as described above. For example, there may be only one display panel 110, and the display area of the single display panel 110 may be divided into two so that an image for the right eye is displayed in the right half area and an image for the left eye is displayed in the left half area.

The display control circuit 112 includes a driver IC (Integrated Circuit) 115, a signal line connection circuit 113, and a scanning line drive circuit 114. The signal line connection circuit 113 is electrically connected to the signal line SL. The driver IC 115 controls the ON/OFF of a switching element (e.g., a TFT) for controlling the operation (light transmittance) of the pixel Pix by the scanning line drive circuit 114. The scanning line drive circuit 114 is electrically connected to the scanning line GL.

The sensor 120 detects information that allows the orientation of the user's head to be estimated. For example, the sensor 120 detects information indicating the movement of the display device 100 or the mounting member 400, and the display system 1 estimates the orientation of the head of the user wearing the display device 100 on their head based on the information indicating the movement of the display device 100 or the mounting member 400.

The sensor 120 detects information that can estimate the direction of the line of sight, for example, using at least one of the angle, acceleration, angular velocity, orientation, and distance of the display device 100 or the mounting member 400. The sensor 120 can use, for example, a gyro sensor, an acceleration sensor, an orientation sensor, etc. The sensor 120 may detect, for example, the angle and angular velocity of the display device 100 or the mounting member 400 by a gyro sensor. The sensor 120 may detect, for example, the direction and magnitude of the acceleration acting on the display device 100 or the mounting member 400 by an acceleration sensor. The sensor 120 may detect, for example, the orientation of the display device 100 by an orientation sensor. The sensor 120 may detect the movement of the display device 100 or the mounting member 400 by, for example, a distance sensor, a GPS (Global Positioning System) receiver, etc. The sensor 120 may be any other sensor such as an optical sensor, or a combination of multiple sensors, as long as it is a sensor for detecting the direction of the user's head, changes in line of sight, movement, etc. The sensor 120 is electrically connected to the image separation circuit 150 via the interface 160, which will be described later.

The image separation circuit 150 receives image data for the left eye and image data for the right eye sent from the control device 200 via the cable 300, sends the image data for the left eye to the display panel 110 that displays the image for the left eye, and sends the image data for the right eye to the display panel 110 that displays the image for the right eye.

The interface 160 includes a connector to which the cable 300 (FIG. 1) is connected. A signal from the control device 200 is input to the interface 160 via the connected cable 300. The image separation circuit 150 outputs the signal input from the sensor 120 to the control device 200 via the interface 160 and the interface 240. Here, the signal input from the sensor 120 includes information that allows the above-mentioned line of sight direction to be estimated. Alternatively, the signal input from the sensor 120 may be output directly to the control unit 230 of the control device 200 via the interface 160. The interface 160 may be, for example, a wireless communication device, and may transmit and receive information to and from the control device 200 via wireless communication.

The control device 200 includes an operation unit 210, a memory unit 220, a control unit 230, and an interface 240.

The operation unit 210 accepts user operations. The operation unit 210 can use input devices such as a keyboard, buttons, and a touch screen. The operation unit 210 is electrically connected to the control unit 230. The operation unit 210 outputs information corresponding to the operation to the control unit 230.

The storage unit 220 stores programs and data. The storage unit 220 temporarily stores the processing results of the control unit 230. The storage unit 220 includes a storage medium. The storage medium includes, for example, a ROM, a RAM, a memory card, an optical disk, or a magneto-optical disk. The storage unit 220 may store data of an image to be displayed on the display device 100.

The memory unit 220 stores, for example, a control program 211, a VR application 212, etc. The control program 211 can provide, for example, various control functions for operating the control device 200. The VR application 212 can provide a function for displaying a virtual reality image on the display device 100. The memory unit 220 can store, for example, various information input from the display device 100, such as data indicating the detection results of the sensor 120.

The control unit 230 includes, for example, an MCU (Micro Control Unit), a CPU (Central Processing Unit), etc. The control unit 230 can comprehensively control the operation of the control device 200. Various functions of the control unit 230 are realized based on the control of the control unit 230.

The control unit 230 includes, for example, a GPU (Graphics Processing Unit) that generates an image to be displayed. The GPU generates an image to be displayed on the display device 100. The control unit 230 outputs the image generated by the GPU to the display device 100 via the interface 240. In this embodiment, the control unit 230 of the control device 200 includes a GPU, but is not limited to this. For example, the GPU may be provided in the display device 100 or the image separation circuit 150 of the display device 100. In this case, the display device 100 acquires data, for example, from the control device 200, an external electronic device, etc., and the GPU generates an image based on the data.

The interface 240 includes a connector to which the cable 300 (see FIG. 1) is connected. A signal from the display device 100 is input to the interface 240 via the cable 300. The interface 240 outputs a signal input from the control unit 230 to the display device 100 via the cable 300. The interface 240 may be, for example, a wireless communication device, and may transmit and receive information to and from the display device 100 via wireless communication.

When the control unit 230 executes the VR application 212, it causes the display device 100 to display an image according to the movement of the user (display device 100). When the control unit 230 detects a change in the user (display device 100) while an image is being displayed on the display device 100, it changes the image displayed on the display device 100 to an image in the changed direction. When the control unit 230 starts creating an image, it creates an image based on a reference viewpoint and reference line of sight in the virtual space, and when it detects a change in the user (display device 100), it changes the viewpoint or line of sight when creating the displayed image from the reference viewpoint or reference line of sight direction according to the movement of the user (display device 100), and causes the display device 100 to display an image based on the changed viewpoint or line of sight.

For example, the control unit 230 detects a movement of the user's head to the right based on the detection result of the sensor 120. In this case, the control unit 230 changes the currently displayed image to an image that appears when the line of sight is shifted to the right. The user can view an image to the right of the image displayed on the display device 100.

For example, when the control unit 230 detects movement of the display device 100 based on the detection result of the sensor 120, it changes the image according to the detected movement. When the control unit 230 detects that the display device 100 has moved forward, it changes the image to one that would appear if the display device 100 had moved forward from the currently displayed image. When the control unit 230 detects that the display device 100 has moved backward, it changes the image to one that would appear if the display device 100 had moved backward from the currently displayed image. The user can visually recognize an image in the direction of his or her own movement from the image displayed on the display device 100.

Figure 4 is a circuit diagram showing the pixel array of the display area according to the first embodiment. Hereinafter, the above-mentioned scanning line GL collectively refers to the multiple scanning lines G1, G2, and G3. The above-mentioned signal line SL collectively refers to the multiple signal lines S1, S2, and S3. In this disclosure, the scanning line GL and the signal line SL do not intersect at right angles, but in Figure 3, for convenience of explanation, the scanning line GL and the signal line SL are perpendicular to each other.

In the display region 111, switching elements TrD1, TrD2, TrD3, signal lines SL, scanning lines GL, etc. of the pixels PixR, PixG, and PixB shown in FIG. 4 are formed. The signal lines S1, S2, and S3 are wiring for supplying pixel signals to the pixel electrodes PE1, PE2, and PE3 (see FIG. 8). The scanning lines G1, G2, and G3 are wiring for supplying gate signals that drive the switching elements TrD1, TrD2, and TrD3.

The pixel Pix in the display area 111 shown in FIG. 4 includes a plurality of pixels PixR, PixG, and PixB arranged in an array. Hereinafter, the plurality of pixels PixR, PixG, and PixB may be collectively referred to as pixel Pix. The pixels PixR, PixG, and PixB each include a switching element TrD1, TrD2, and TrD3 and a liquid crystal layer LC capacitance. The switching elements TrD1, TrD2, and TrD3 are made of thin film transistors, and in this example, are made of n-channel MOS (Metal Oxide Semiconductor) type TFTs. A sixth insulating film 16 (see FIG. 8) is provided between the pixel electrodes PE1, PE2, and PE3 described later and the common electrode COM, and these form the storage capacitance Cs shown in FIG. 4.

The color filters CFR, CFG, and CFB shown in FIG. 4 are arranged in a cyclical fashion in three color regions, for example, red (first color: R), green (second color: G), and blue (third color: B). A set of R, G, and B color regions is associated with each of the pixels PixR, PixG, and PixB shown in FIG. 4 described above. The pixels PixR, PixG, and PixB corresponding to the three color regions are considered to be a set. Note that the color filter may include four or more color regions. The pixels PixR, PixG, and PixB may each be called a subpixel.

Fig. 5 is a schematic diagram showing an example of a display panel according to the first embodiment. Fig. 6 is a schematic diagram showing an enlarged view of a part of a display area in the first embodiment. Fig. 7 is a schematic diagram showing the relationship between signal lines and scanning lines in Fig. 6. Fig. 8 is a cross-sectional view showing a cross section taken along line VIII-VIII' in Fig. 7.

As shown in FIG. 5, the display panel 110 has sides 110e1, 110e2, 110e3, and 110e4 at the ends of the substrate. The areas between the display area 111 and the sides 110e1, 110e2, 110e3, and 110e4 at the ends of the substrate of the display panel are called the peripheral area.

The scanning line driving circuit 114 is disposed in the peripheral region between the edge 110e1 of the substrate end of the display panel 110 and the display area 111. The signal line connection circuit 113 is disposed in the peripheral region between the edge 110e4 of the substrate end of the display panel 110 and the display area 111. The driver IC 115 is disposed in the peripheral region between the edge 110e4 of the substrate end of the display panel 110 and the display area 111.

The driver IC 115 is joined to the terminals 115b via a conductive member in order to electrically connect to the array substrate SUB1 (see FIG. 8) of the display panel 110, which will be described later. The terminals 115b are generally arranged in one direction, and the direction Vp in which the terminals 115b are arranged is defined as the direction Vx. The direction Vy is a direction perpendicular to the direction Vx. In this embodiment, the sides 110e3 and 110e4 at the ends of the substrate of the display panel 110 are parallel to the direction Vx. The sides 110e1 and 110e2 at the ends of the substrate of the display panel 110 are parallel to the direction Vy.

As shown in FIG. 5, the direction in which the signal line SL extends is parallel to the direction Vy. The direction in which the scanning line GL extends is not parallel to either the direction Vx or the direction Vy. Since the direction in which the scanning line GL extends is non-orthogonal to the direction in which the signal line SL extends, for example, each pixel PixR, PixG, and PixB is a parallelogram.

Although the pixels PixR, PixG, and PixB are illustrated as parallelograms, the shape is not limited to parallelograms. For example, as shown in FIG. 6, the pixels PixR, PixG, and PixB are aligned and shifted in the direction Vy. If the length of each pixel PixR, PixG, and PixB in the direction Vx is a distance Pw1, and the length of each pixel PixR, PixG, and PixB in the direction Vy is a distance Ph1, then there is a relationship of Pw1:Ph1=1:3. Each pixel PixR, PixG, and PixB may also be referred to as a subpixel PixS.

In FIG. 6, the direction Vsl is the direction in which the signal line SL (see FIG. 5) extends. The direction Vsg, which is perpendicular to the direction Vsl, is parallel to the direction Vx. The direction Vss is the direction in which the scanning line GL (see FIG. 5) extends. The scanning line GL is inclined with respect to the direction Vx by an angle θg formed by the directions Vss and Vsg. The directions Vsl and Vss will be described in detail with reference to FIG. 7.

As shown in FIG. 7, the direction Vss is the direction in which a virtual line that connects the first reference positions Pgl in multiple pixels PixR connected to one scanning line GL extends. For example, the first reference position Pgl is on the scanning line GL, intersects with the scanning line GL in a planar view, and is the midpoint of the adjacent signal lines SL. The first reference position Pgl is not limited to this, and may be, for example, the area center of gravity of pixel PixR. Note that while the first reference position Pgl is defined based on pixel PixR, pixel PixG or pixel PixB may be used instead of pixel PixR.

As shown in FIG. 7, the direction Vsl is the direction in which a virtual line that connects the second reference positions Psl in multiple pixels PixR that are connected to one signal line SL extends. For example, the second reference position Psl is on the signal line SL, and is the midpoint of the intersection position Pt between the signal line SL and the scanning line GL that intersects with this signal line SL in a planar view. The second reference position Psl is not limited to this, and may be, for example, the area center of gravity of pixel PixR. Note that, although the second reference position Psl is defined based on pixel PixR as a reference, pixel PixG or pixel PixB may be used instead of pixel PixR.

As shown in FIG. 7, pixel PixR and adjacent pixel PixG are arranged with a distance Δh1 offset in the direction Vsl. Two pixels PixR connected to one scanning line GL are offset by three times the distance Δh1. If half the distance Ph1 shown in FIG. 6 is equal to three times the distance Δh1 shown in FIG. 7, pixels of the same color adjacent in the direction Vx, for example, pixels PixR, are offset by half in the direction Vsl. Therefore, pixels of the same color take two types of positions in even and odd columns. As a result, horizontal black and white lines can be displayed more finely, and the effective resolution of the display device 100 is improved. Note that when the scanning line GL shown in FIG. 7 extends linearly along the direction Vss, each pixel PixR, PixG, and PixB becomes a parallelogram as shown in FIG. 5.

Next, the cross-sectional structure of the display panel 110 will be described with reference to FIG. 8. In FIG. 8, the array substrate SUB1 is based on a first insulating substrate 10 having translucency, such as a glass substrate or a resin substrate. The array substrate SUB1 includes a first insulating film 11, a second insulating film 12, a third insulating film 13, a fourth insulating film 14, a fifth insulating film 15, a sixth insulating film 16, signal lines S1 to S3, pixel electrodes PE1 to PE3, a common electrode COM, a first alignment film AL1, and the like, on the side of the first insulating substrate 10 facing the counter substrate SUB2. In the following description, the direction from the array substrate SUB1 toward the counter substrate SUB2 is referred to as the upward direction, or simply as the upward direction.

The first insulating film 11 is located on the first insulating substrate 10. The second insulating film 12 is located on the first insulating film 11. The third insulating film 13 is located on the second insulating film 12. The signal lines S1 to S3 are located on the third insulating film 13. The fourth insulating film 14 is located on the third insulating film 13 and covers the signal lines S1 to S3.

If necessary, wiring may be disposed on the fourth insulating film 14. This wiring will be covered by the fifth insulating film 15. In this embodiment, the wiring is omitted. The first insulating film 11, the second insulating film 12, the third insulating film 13, and the sixth insulating film 16 are formed of an inorganic material having translucency, such as silicon oxide or silicon nitride. The fourth insulating film 14 and the fifth insulating film 15 are formed of a resin material having translucency, and have a thickness greater than the other insulating films formed of inorganic materials. However, the fifth insulating film 15 may be formed of an inorganic material.

The common electrode COM is located on the fifth insulating film 15. The common electrode COM is covered by the sixth insulating film 16. The sixth insulating film 16 is formed of an inorganic material having translucency, such as silicon oxide or silicon nitride.

The pixel electrodes PE1 to PE3 are located on the sixth insulating film 16 and face the common electrode COM via the sixth insulating film 16. The pixel electrodes PE1 to PE3 and the common electrode COM are formed of a conductive material having translucency, such as ITO (Indium Tin Oxide) or IZO (Indium Zinc Oxide). The pixel electrodes PE1 to PE3 are covered by the first alignment film AL1. The first alignment film AL1 also covers the sixth insulating film 16.

The counter substrate SUB2 is based on a second insulating substrate 20 having light-transmitting properties, such as a glass substrate or a resin substrate. The counter substrate SUB2 is provided with a light-shielding layer BM, color filters CFR, CFG, CFB, an overcoat layer OC, a second alignment film AL2, etc., on the side of the second insulating substrate 20 facing the array substrate SUB1.

As shown in FIG. 8, the light-shielding layer BM is located on the side of the second insulating substrate 20 facing the array substrate SUB1. The light-shielding layer BM defines the size of the openings facing the pixel electrodes PE1 to PE3. The light-shielding layer BM is made of a black resin material or a light-shielding metal material.

Each of the color filters CFR, CFG, and CFB is located on the side of the second insulating substrate 20 facing the array substrate SUB1, and each end overlaps the light-shielding layer BM. Color filter CFR faces pixel electrode PE1. Color filter CFG faces pixel electrode PE2. Color filter CFB faces pixel electrode PE3. In one example, color filters CFR, CFG, and CFB are formed from resin materials colored blue, red, and green, respectively.

The overcoat layer OC covers the color filters CFR, CFG, and CFB. The overcoat layer OC is made of a resin material having light-transmitting properties. The second alignment film AL2 covers the overcoat layer OC. The first alignment film AL1 and the second alignment film AL2 are made of a material that exhibits horizontal alignment properties, for example.

As described above, the counter substrate SUB2 includes a light-shielding layer BM, color filters CFR, CFG, CFB, etc. The light-shielding layer BM is disposed in an area facing the wiring parts such as the scanning lines G1, G2, G3, the signal lines S1, S2, S3, the contact parts PA1, PA2, PA3, and the switching elements TrD1, TrD2, TrD3 shown in FIG. 4.

In FIG. 8, the counter substrate SUB2 has three color filters CFR, CFG, and CFB, but it may have four or more color filters including color filters of colors other than blue, red, and green, such as white, transparent, yellow, magenta, and cyan. These color filters CFR, CFG, and CFB may also be provided on the array substrate SUB1.

In addition, in FIG. 8, the color filter CF is provided on the counter substrate SUB2, but the color filter CF may be provided on the array substrate SUB1, which is a so-called COA (Color filter on Array) structure.

The array substrate SUB1 and counter substrate SUB2 described above are arranged so that the first alignment film AL1 and the second alignment film AL2 face each other. The liquid crystal layer LC is sealed between the first alignment film AL1 and the second alignment film AL2. The liquid crystal layer LC is made of a negative type liquid crystal material with a negative dielectric anisotropy, or a positive type liquid crystal material with a positive dielectric anisotropy.

The array substrate SUB1 faces the backlight IL, and the counter substrate SUB2 is located on the display surface side. Various types of backlight IL can be used, but detailed explanations of their structures will be omitted.

The first optical element OD1 including the first polarizer PL1 is disposed on the outer surface of the first insulating substrate 10 or on the surface facing the backlight IL. The second optical element OD2 including the second polarizer PL2 is disposed on the outer surface of the second insulating substrate 20 or on the surface facing the observation position. The first polarization axis of the first polarizer PL1 and the second polarization axis of the second polarizer PL2 are in a crossed Nicol positional relationship in the XY plane, for example. The first optical element OD1 and the second optical element OD2 may include other optically functional elements such as retardation plates.

For example, when the liquid crystal layer LC is a negative type liquid crystal material, and no voltage is applied to the liquid crystal layer LC, the liquid crystal molecules LM are initially aligned in the Vx-Vy plane with their long axes aligned along a predetermined direction. On the other hand, when a voltage is applied to the liquid crystal layer LC, that is, when an electric field is formed between the pixel electrodes PE1 to PE3 and the common electrode COM during the on-state, the alignment state of the liquid crystal molecules LM changes under the influence of the electric field. When the polarization state of the incident linearly polarized light changes according to the alignment state of the liquid crystal molecules LM as it passes through the liquid crystal layer LC.

As described above, the display device 100 has a display area 111 that is viewed through the lens 410. The display area 111 is provided on the array substrate SUB1. The display area 111 includes a plurality of pixels PixR, PixG, and PixB, a plurality of scanning lines GL extending in a first direction Vss, and a plurality of signal lines SL extending in a second direction Vsl. The first direction Vss is non-parallel and non-orthogonal to a direction perpendicular to the second direction Vsl. The first pixel PixR, the second pixel PixG, and the third pixel PixB are each arranged continuously in the second direction Vsl. One first pixel PixR and the next first pixel PixR arranged in the first direction Vss from the first pixel PixR are arranged so as to be shifted in the second direction Vsl by half the distance Ph1 of the first pixel PixR. This improves the effective resolution of the display device 100.

Next, since the direction Vss in which the scanning lines GL extend is non-orthogonal to the direction Vsl in which the signal lines SL extend, the display system 1 performs a compensation process on the image so that the image recognized by the user is not distorted. FIG. 9A is a diagram showing an example of an image input to the display system according to the first embodiment. FIG. 9B is a diagram showing an example of a compensation process that compensates for distortion of an image displayed by the display system according to the first embodiment.

In the example shown in FIG. 9A, an image Mn to be displayed to the user is arranged in a matrix in directions Vx and Vy. The GPU of the control unit 230 shown in FIG. 3 calculates a first compensation image MI by applying an image transformation process to the image Mn shown in FIG. 9A to correct the lens distortion of the lens 410 (see FIG. 2). The GPU of the control unit 230 shown in FIG. 3 calculates a second compensation image Mg by applying an image transformation process to compensate for the distortion that transforms the image Mn shown in FIG. 9A due to the influence of the angle θg. The GPU of the control unit 230 shown in FIG. 3 sends a third compensation image MIg, which is obtained by superimposing the first compensation image MI and the second compensation image Mg on the image Mn shown in FIG. 9A, to the display device 100.

In addition, in FIG. 9B, the two image transformation processes of the first compensation image MI and the second compensation image Mg to finally obtain the third compensation image Mlg are processed at once by a texture mapping method commonly used in image processing using a GPU. Specifically, the image of the texture mapped to the polygon mesh (image) reflecting the distortion that is the target of the third compensation image Mlg in FIG. 9B becomes the distorted image element of the target third compensation image Mlg. For this reason, the polygon mesh (image) corresponding to the third compensation image Mlg is stored in the storage unit 220, or the polygon mesh (image) of the third compensation image Mlg is generated by calculation in the control unit 230 when the display system 1 is started, and the polygon mesh (image) can be applied during the display processing of each frame. As a result, the final target third compensation image Mlg result can be obtained with just one texture mapping process. This does not increase the number of image processing steps compared to general VR image distortion compensation processing that does not involve processing of the second compensation image Mg and only applies the first compensation image Ml, so it is possible to suppress any increase in costs due to the execution of processing of the second compensation image Mg in this embodiment.

As described above, the control device 200 executes a second compensation process to compensate for distortion that distorts the image due to the influence of the angle θg that the first direction Vss in which the scanning line GL extends makes with respect to the direction Vsg perpendicular to the second direction Vsl. As a result, the display device 100 can display the third compensation image MIg, thereby allowing the user to recognize the image Mn shown in FIG. 9A.

The second compensation process may be performed by the driver IC 115 of the display control circuit 112 described above. The driver IC 115 executes the second compensation process to compensate for the distortion that distorts the image due to the influence of the angle θg. This allows the control device 200 to reduce the computational load on the GPU.

(Embodiment 2)
In the first embodiment, the direction Vsl is parallel to the direction Vy, but in the second embodiment, the direction Vsl is inclined at an angle θs with respect to the direction Vy. In the following description, the same components may be denoted by the same reference numerals. Furthermore, duplicated descriptions will be omitted.

In FIG. 10, the direction Vsl is the direction in which the signal line SL (see FIG. 7) extends. The direction Vsg, which is perpendicular to the direction Vsl, has an angle θs with respect to the direction Vx. The direction Vss is the direction in which the scanning line GL (see FIG. 7) extends. As described above, the direction Vss and the direction Vsg form an angle θg. Therefore, the angle at which the scanning line GL is inclined with respect to the direction Vx is the angle (θg-θs).

Compared to the display device 100 of the first embodiment, the display device 100 of the second embodiment has a smaller angle of inclination of the scanning lines GL with respect to the direction Vx. This reduces the load of the image transformation process that suppresses the effect of the angle θg that the direction in which the scanning lines GL extend and the direction perpendicular to the direction in which the signal lines SL extend.

(Embodiment 3)
In the first embodiment, there is one scanning line driving circuit 114, but in the third embodiment, there are two scanning line driving circuits. In the following description, the same components as those in the first and second embodiments are denoted by the same reference numerals, and duplicated description will be omitted.

11 is a schematic diagram showing an example of a display area according to the third embodiment. As shown in FIG. 11, the first scanning line driving circuit 114A is arranged in a peripheral area between the side 110e1 of the substrate end of the display panel 110 and the display area 111. The second scanning line driving circuit 114B is arranged in a peripheral area between the side 110e2 of the substrate end of the display panel 110 and the display area 111. The second scanning line driving circuit 114B is arranged on the opposite side of the first scanning line driving circuit 114A across the display area 111. The scanning lines GL connected to the first scanning line driving circuit 114A and the scanning lines GL connected to the second scanning line driving circuit 114B are alternately arranged at a predetermined interval in the direction Vy. This allows the number of output circuits of each of the scanning line driving circuits 114A and 114B to be reduced by half, and a scanning line driving circuit can be formed even if the pixel pitch is narrowed.

Because the scanning line GL is inclined with respect to the direction Vx, the second scanning line driving circuit 114B is shifted in the direction Vy from the first scanning line driving circuit 114A. The area surrounded by the signal line SL and the scanning line GL can be any of the pixels PixR, PixG, and PixB. Here, on the side 110e4 of the substrate end, there is an area that is not the display area 111 even if it is surrounded by the signal line SL and the scanning line GL. Therefore, the scanning line GL connected to the first scanning line driving circuit 114A close to the side 110e4 of the substrate end is shorter in length than the scanning line GL connected to the second scanning line driving circuit 114B. Conversely, the scanning line GL connected to the second scanning line driving circuit 114B close to the side 110e3 of the substrate end is shorter in length than the scanning line GL connected to the first scanning line driving circuit 114A.

(Embodiment 4)
In the third embodiment, the first scanning line driving circuit 114A is arranged in a straight line extending in the direction Vy, but in the fourth embodiment, the first scanning line driving circuit 114A is bent. In the following description, the same reference numerals are used for the same components as those in the first to third embodiments, and redundant description will be omitted.

FIG. 12 is a schematic diagram showing an example of a display area according to the fourth embodiment. Since the scanning lines GL are inclined with respect to the direction Vx, the second scanning line driving circuit 114B is shifted in the direction Vy from the first scanning line driving circuit 114A. Therefore, the first scanning line driving circuit 114A has a straight portion 114C extending in the direction Vy and a straight portion 114D extending in the direction Vx. The straight portion 114C and the straight portion 114D are connected by a bent portion 114X. As a result, the straight portion 114D is disposed in the peripheral region between the side 110e3 at the end of the substrate and the display area 111, so that the length in the direction Vy of the display panel 110 of the fourth embodiment can be made shorter than that of the third embodiment.

(Embodiment 5)
In the first embodiment, pixels Pix of the same color are consecutively arranged in the direction Vsl, but in the fifth embodiment, pixels Pix of the same color are not consecutively arranged in the direction Vsl. In the following description, the same reference numerals are used for components similar to those in the first to fourth embodiments, and redundant description will be omitted.

Figure 13 is a schematic diagram showing an enlarged portion of the display area in the fifth embodiment. Figure 14 is a schematic diagram showing the relationship between the signal lines and the scanning lines in Figure 13. Figure 15 is an explanatory diagram showing the relationship between the ratio of the same-color pixel interval to the reference distance of the pixels in the second direction and the inclination of the scanning lines in the fifth embodiment. As shown in Figure 5, in the fifth embodiment as well, the direction in which the signal lines SL extend is parallel to the direction Vy. The direction in which the scanning lines GL extend is not parallel to either the direction Vx or the direction Vy. Since the direction in which the scanning lines GL extend is non-orthogonal to the direction in which the signal lines SL extend, for example, each pixel PixR, PixG, and PixB is a parallelogram.

In FIG. 13, the direction Vsl is the direction in which the signal line SL (see FIG. 5) extends. The direction Vsg, which is perpendicular to the direction Vsl, is parallel to the direction Vx. The direction Vss is the direction in which the scanning line GL (see FIG. 5) extends. The scanning line GL is inclined with respect to the direction Vx by an angle θg formed by the directions Vss and Vsg. The directions Vsl and Vss will be described in detail with reference to FIG. 14.

Although a parallelogram is illustrated as an example of each pixel PixR, PixG, and PixB, the shape is not limited to a parallelogram. As shown in FIG. 14, the direction Vss is the direction in which an imaginary line connecting first reference positions Pgl in multiple pixels PixR connected to one scanning line GL extends. For example, the first reference position Pgl is on the scanning line GL, intersects with the scanning line GL in a planar view, and is the midpoint of the adjacent signal line SL.

The direction Vsl is the direction in which a virtual line connecting the second reference positions Psl in multiple pixels PixR connected to one signal line SL extends. For example, the second reference position Psl is on the signal line SL and is the midpoint of the intersection position Pt between the signal line SL and the scanning line GL that intersects with this signal line SL in a planar view.

As shown in FIG. 14, pixel PixR and adjacent pixel PixG are arranged with a distance Δh2 offset in the direction Vsl. Δh2 is approximately equal to Pw2×tan(θg).

The display system 1 shown in FIG. 1 is worn on the user's head, so it is desirable for the display device 100 to be small. In this way, in a situation where the size of the display panel 110 is restricted, the display area 111 is viewed through the lens 410, so in order to increase the resolution, it is necessary to make the pixels Pix smaller. For example, in the pixel array shown in FIG. 7, the length of the pixels PixR, PixG, and PixB in the direction Vx is the distance Pw1. For example, if the distance Pw1 is reduced to 12 μm, the area ratio of the light-shielding layer BM described above increases, the aperture ratio decreases, and there is a possibility that power consumption will increase in order to ensure a certain level of brightness.

Therefore, in the fifth embodiment, the pixels PixR, PixG, and PixB are arranged as shown in FIG. 13.

As shown in FIG. 13, in the direction Vss, pixel PixR is sandwiched between pixels PixB and PixG, and in the direction Vsl, pixel PixR is sandwiched between pixels PixB and PixG.

In addition, in the direction Vss, pixel PixG is sandwiched between pixels PixR and PixB, and in the direction Vsl, pixel PixG is sandwiched between pixels PixR and PixB.

In addition, in the direction Vss, pixel PixB is sandwiched between pixels PixG and PixR, and in the direction Vsl, pixel PixB is sandwiched between pixels PixG and PixR.

In the direction Vss, pixels PixR, PixG, and PixB are repeatedly arranged in this order. In the direction Vsl, pixels PixR, PixG, and PixB are repeatedly arranged in this order.

In the pixel array shown in FIG. 14, the length of the pixels PixR, PixG, and PixB in the direction Vx is the distance Pw2, and the length of the pixels PixR, PixG, and PixB in the direction Vy is the distance Ph2. The distance Pw2 is 3/2 times the distance Pw1 shown in FIG. 7, and the distance Ph2 is 2/3 times the distance Ph1 shown in FIG. 7. By arranging the pixels PixR, PixG, and PixB as shown in FIG. 13, the distance Pw2 can be sufficiently secured, and the aperture ratio of the pixels PixR, PixG, and PixB can be improved. Note that when the scanning line GL shown in FIG. 14 extends linearly along the direction Vss, each pixel PixR, PixG, and PixB becomes a parallelogram as shown in FIG. 5.

However, in the arrangement of pixels PixR, PixG, and PixB as shown in FIG. 13, for example, green pixel PixG, which has high visibility to the user, is continuously arranged diagonally (third direction Vt) with respect to direction Vx. Here, when angle θg is 0 degrees, pixel PixG appears as a diagonal line to the user and is easily visible. The phenomenon in which the pixel structure is visible to the user is called the screen door effect.

As described above, the display device 100 has a display area 111 that is viewed through the lens 410. The display area 111 is provided on the array substrate SUB1. The display area 111 includes a plurality of pixels PixR, PixG, and PixB, a plurality of scanning lines GL extending in a first direction Vss, and a plurality of signal lines SL extending in a second direction Vsl. In the display device 100 of the fifth embodiment, if the direction Vss is non-parallel and non-orthogonal to the direction Vx, the screen door effect is unlikely to occur.

As described above, the angle between the direction Vss and the direction Vsg is θg. In FIG. 13, the pixel spacing of the green pixel PixG, which has high visibility to the user, is set to L1 and L2. Here, the distance Ph1 shown in FIG. 7 is set as the reference distance for comparison. FIG. 15 shows the relationship between the angle θg and the ratios of the same-color pixel spacings L1 and L2 to the distance Ph1 shown in FIG. 7.

As shown in FIG. 15, the spacing L1 and spacing L2 between same-color pixels change depending on the angle θg. With spacing L1 and spacing L2, to improve the screen door effect, it is necessary to reduce the spacing L1 between same-color pixels sandwiching different-color pixels in between. Compared to when L1/Ph1 is 1.2, when L1/Ph1 is 1.1 or less and 0.9 or more, the screen door effect is reduced and the user is less likely to see the diagonal line pattern. Note that when L1/Ph1 is 0.8, the user may see the diagonal line pattern.

Therefore, in the display device of embodiment 5, if the angle θg is 10.49 degrees or more and 33.07 degrees or less, L1/Ph1 is 1.1 or less and 0.9 or more, and the screen door effect is reduced. The closer the ratio of the distance L1 to the distance L2 is to 1, the smaller the screen door effect becomes. Therefore, if the angle θg is 12.53 degrees or more and 23.96 degrees or less, the screen door effect becomes smaller.

(Embodiment 6)
16 is an explanatory diagram showing the relationship between the ratio of the same-color pixel interval to the distance serving as the reference for pixels in the second direction and the inclination of the scanning line in the sixth embodiment. In the fifth embodiment described above, in FIG. 14, a pixel array in which the distance Pw2 is 3/2 times the distance Pw1 shown in FIG. 7 and the distance Ph2 is 2/3 times the distance Ph1 shown in FIG. 7 is described. The sixth embodiment differs from the fifth embodiment in that the length of the distance Ph2 shown in the fifth embodiment is different. In the following description, the pixel array of the sixth embodiment will be described with reference to FIGS. 13, 14, and 16. Note that the same reference numerals are used for the same components as those in the first to fifth embodiments, and duplicated descriptions will be omitted.

Also in the sixth embodiment, as shown in FIG. 14, the length in the direction Vx of each pixel PixR, PixG, and PixB in the pixel array is the distance Pw2, and the length in the direction Vy is the distance Ph2. In the sixth embodiment, the distance Pw2 shown in FIG. 14 is 3/2 times the distance Pw1 shown in FIG. 7, and the distance Ph2 shown in FIG. 14 is the same as the distance Ph1 shown in FIG. 7. By arranging each pixel PixR, PixG, and PixB as shown in FIG. 13, the distance Pw2 can be sufficiently secured, and the aperture ratio of each pixel PixR, PixG, and PixB can be improved.

As shown in FIG. 16, the spacing between pixels of the same color, L1/Ph1 and the spacing, L2/Ph1, change depending on the angle θg. With the pixel size of embodiment 6, the spacing, L1/Ph1, is as large as 1.34 when θg = 0 degrees, and it is important to narrow L1/Ph1 so that the diagonal lines caused by the screen door effect are not visible.

When the distance L1/Ph1 is 1.275 or less, which is 5% less than 1.34 when θg=0, and the distance L1/Ph1 is 0.9 or more, the screen door effect is reduced and the diagonal line pattern becomes less visible to the user.

Therefore, in the display device of embodiment 6, if the angle θg is 7.45 degrees or more and 49.72 degrees or less, L1 is 1.275 or less and 0.9 or more, and the screen door effect is reduced.

(Embodiment 7)
In the first to sixth embodiments, the display area 111 is substantially rectangular, but in the seventh embodiment, the display area 111 is circular. In the following description, the same components as those in the first to sixth embodiments are denoted by the same reference numerals, and duplicated descriptions will be omitted.

FIG. 17 is a schematic diagram showing an example of a display area according to the seventh embodiment. The first scanning line driving circuit 114A has a straight line portion 114C extending in the direction Vy, a straight line portion 114E extending in the direction Vx, and a straight line portion 114D connecting the straight line portion 114C and the straight line portion 114E. The straight line portion 114C and the straight line portion 114D are connected by a bent portion 114X1. The straight line portion 114D and the straight line portion 114E are connected by a bent portion 114X2. Since the display area 111 is circular, the straight line portion 114C, the straight line portion 114D, and the straight line portion 114E are aligned along the display area 111. As a result, the display panel 110 according to the seventh embodiment can have a smaller peripheral area than the display panel 110 according to the third embodiment.

The second scanning line driving circuit 114B has a straight portion 114F extending in the direction Vy and a straight portion 114G extending in a direction inclined with respect to the direction Vy. The straight portion 114F and the straight portion 114G are connected by a bent portion 114X3. Since the display area 111 is circular, the straight portion 114F and the straight portion 114G are aligned along the display area 111. As a result, the display panel 110 of the seventh embodiment can have a smaller peripheral area than the third embodiment.

Note that the signal line connection circuit 113 in embodiment 7 is non-parallel to the direction Vx.

As described above, the user views the display area of the display device 100 enlarged by the lens 410. When the user views the display area 111 through the lens 410, the peripheral parts of the display panel 110, particularly the corner parts far from the center, are often outside the field of view of the lens and cannot be seen. For this reason, even if the display area 111 is circular, the user can view the image without feeling uncomfortable.

(Embodiment 8)
In the seventh embodiment, the display area 111 is circular, whereas in the eighth embodiment, the display area 111 is polygonal. The same components as those in the first embodiment are given the same reference numerals, and duplicated explanations will be omitted.

Figure 18 is a schematic diagram showing an example of a display area according to embodiment 8. Display area 111 according to embodiment 8 is a hexagon among polygons. This reduces the non-display area between straight line portion 114C, straight line portion 114D, straight line portion 114E, straight line portion 114F, and straight line portion 114G and display area 111. As a result, display panel 110 according to embodiment 8 can ensure the area of display area 111 even if the peripheral area is reduced.

(Embodiment 9)
In the embodiment 9, the pixels PixR, PixG, and PixB are arranged in the direction Vss in an order different from that of the embodiment 5. The same components as those in the above-described embodiments are denoted by the same reference numerals, and duplicated explanations will be omitted.

Figure 19 is a schematic diagram showing an enlarged view of a portion of the display area in embodiment 9. As shown in Figure 19, in the direction Vss, pixel PixR is sandwiched between pixels PixB and PixG, and in the direction Vsl, pixel PixR is sandwiched between pixels PixB and PixG.

In addition, in the direction Vss, pixel PixG is sandwiched between pixels PixR and PixB, and in the direction Vsl, pixel PixG is sandwiched between pixels PixR and PixB.

In addition, in the direction Vss, pixel PixB is sandwiched between pixels PixG and PixR, and in the direction Vsl, pixel PixB is sandwiched between pixels PixG and PixR.

In the direction Vss, pixels PixR, PixB, and PixG are repeatedly arranged in this order. In the direction Vsl, pixels PixR, PixB, and PixG are repeatedly arranged in this order. Green pixels PixG, which have high visibility to the user, are continuously arranged diagonally (in a third direction Vt) with respect to the direction Vx. The same-color pixel spacings L1 and L2 are the same as in the fifth embodiment, so a description thereof will be omitted.

(Embodiment 10)
The inclination of the direction Vss is downward to the right on the page in the fifth embodiment, whereas the inclination of the direction Vss is upward to the right on the page in the tenth embodiment. The same components as those in the above-mentioned embodiments are given the same reference numerals, and duplicated explanations will be omitted.

Figure 20 is a schematic diagram showing an enlarged view of a portion of the display area in embodiment 10. As shown in Figure 20, in the direction Vss, pixel PixR is sandwiched between pixels PixB and PixG, and in the direction Vsl, pixel PixR is sandwiched between pixels PixB and PixG.

In addition, in the direction Vss, pixel PixG is sandwiched between pixels PixR and PixB, and in the direction Vsl, pixel PixG is sandwiched between pixels PixR and PixB.

In addition, in the direction Vss, pixel PixB is sandwiched between pixels PixG and PixR, and in the direction Vsl, pixel PixB is sandwiched between pixels PixG and PixR.

In the direction Vss, pixels PixR, PixG, and PixB are repeatedly arranged in this order. In the direction Vsl, pixels PixR, PixB, and PixG are repeatedly arranged in this order.

In FIG. 20, the direction Vsg, which is perpendicular to the direction Vsl, is parallel to the direction Vx. The direction Vss is the direction in which the scanning line GL extends.

In the twelfth embodiment, an example of a backlight IL (see FIG. 8) will be described. The same components as those in the above-described embodiments are given the same reference numerals, and duplicated descriptions will be omitted.

FIG. 22 is a block diagram showing an example of the configuration of a display system according to the twelfth embodiment. FIG. 23 is a schematic diagram showing an example of a backlight according to the twelfth embodiment. FIG. 24 is a flowchart for explaining the processing of an image adjustment circuit according to the twelfth embodiment. As shown in FIG. 22, the display device 100 includes two display panels 110, a sensor 120, an image separation circuit 150, an image adjustment circuit 170, and an interface 160. As shown in FIG. 8, a backlight IL is disposed on the rear surface of each of the two display panels 110. For ease of explanation, the backlight IL is illustrated in FIG. 22. As shown in FIG. 22, the image adjustment circuit 170 includes an input image conversion unit 171, a lighting amount calculation unit 172, a luminance distribution calculation unit 175, and a gradation value correction unit 174.

The backlight IL is a so-called direct light source device. The backlight IL is subjected to light source control called local dimming, and the illumination level is controlled for each partial light-emitting area PLA, which is a part of the light-emitting area 511.

Each of the two backlights IL has a light-emitting area 511 and a light source control circuit 512. In the light-emitting area 511, partial light-emitting areas PLA are arranged in a two-dimensional matrix.

In one partial light-emitting area PLA in embodiment 12, for example, pixels Pix of 200 pixels vertically and 200 pixels horizontally overlap. In FIG. 22, the arrangement of multiple partial light-emitting areas PLA is shown diagrammatically, and the size of the partial light-emitting area PLA relative to the pixel Pix differs from the actual size in order to facilitate explanation.

The backlight IL has light-emitting element scanning lines LGL that select light-emitting elements extending in the Vx direction, and light-emitting output signal lines LSL that extend in the Vy direction perpendicular to the Vx direction. In the backlight IL, light-emitting elements are arranged in the area surrounded by the light-emitting output signal lines LSL and the light-emitting element scanning lines LGL.

Of the two backlights IL, the backlight IL that is superimposed on the display area 111 of one display panel 110 is for the right eye, and the backlight IL that is superimposed on the display area 111 of the other display panel 110 is for the left eye. In the twelfth embodiment, a case will be described in which the backlight IL has two backlights IL for the left eye and the right eye. However, the backlight IL is not limited to the structure using two backlights IL as described above. For example, there may be one backlight IL, with the display panel 110 superimposed on the right half area and the display panel 110 for the left eye superimposed on the left half area, and the light-emitting area 511 of the single backlight IL may be superimposed on the display areas 111 for the left eye and the right eye.

The image separation circuit 150 receives image data for the left eye and image data for the right eye sent from the control device 200 via the cable 300, sends the image data for the left eye to the image adjustment circuit 170 of the display panel 110 that displays the image for the left eye, and sends the image data for the right eye to the image adjustment circuit 170 of the display panel 110 that displays the image for the right eye. The detailed configuration of the image adjustment circuit 170 will be described later.

In the 12th embodiment, in the display region 111, the direction in which the scanning lines GL extend is non-orthogonal to the direction in which the signal lines SL extend, as in the 5th embodiment. The display panel 110 of the 12th embodiment has the same configuration as the display panel of the 5th embodiment, and therefore a detailed description thereof is omitted.

As shown in FIG. 23, the light-emitting element 516 is an inorganic light-emitting diode (LED) chip having a size of about 3 μm to 300 μm in plan view, and is called a micro LED or mini LED. The light-emitting output signal line LSL extends in the Vy direction and is connected to the cathode of the light-emitting element 516. The light-emitting output signal lines LSL are arranged at intervals in the Vx direction. The light-emitting element scanning lines LGL extend in the Vx direction, are arranged at intervals in the Vy direction, and are connected to the anode of the light-emitting element 516.

To one light-emitting element scanning line LGL, a plurality of light-emitting elements 516 arranged along the extension direction of the light-emitting element scanning line LGL are connected. Also, to one light-emitting element output signal line LSL, a plurality of light-emitting elements 516 arranged along the extension direction of the light-emitting element output signal line LSL are connected.

22 and 23, the light source control circuit 512 includes a light emission current control circuit 513, a switch array 514, and a timing control circuit 515. The light emission current control circuit 513 is electrically connected to each of the light emission output signal lines LSL. Based on the lighting amount data Dla, the light emission current control circuit 513 supplies current to each of the light emission output signal lines LSL. The switch array 514 includes a plurality of switching elements Lsw (e.g., FET (Field Effect Transistor)) that select each light emission element scanning line LGL. When the switching element Lsw is turned ON, the light emission element scanning line LGL connected to the switching element Lsw is selected. Based on the light source synchronization signal Dsync, the timing control circuit 515 controls the light emission current control circuit 513 and the switch array 514. The switch array 514 turns the switching elements Lsw ON/OFF based on the light emission element scan signal Dsw.

For example, in embodiment 12, as shown in FIG. 23, one partial light-emitting area PLA has one light-emitting element 516. Note that one partial light-emitting area PLA may have a predetermined number of light-emitting elements 516.

As described above, in FIG. 13, the direction Vsl is the direction in which the signal line SL (see FIG. 5) extends. The direction Vsg, which is perpendicular to the direction Vsl, is parallel to the direction Vx. The direction Vss is the direction in which the scanning line GL (see FIG. 5) extends. The scanning line GL is inclined with respect to the direction Vx by the angle θg formed by the direction Vss and the direction Vsg. In contrast, the extension direction of the light-emitting element scanning line LGL is parallel to the direction Vx. The scanning line GL is inclined with respect to the light-emitting element scanning line LGL by the angle θg formed by the extension direction of the light-emitting element scanning line LGL and the extension direction of the scanning line GL. It is necessary to determine the lighting amount taking into account this difference in inclination and calculate the brightness of the backlight at the position of each pixel.

Therefore, in the twelfth embodiment, as shown in FIG. 24, the input image conversion unit 171 converts the shear-deformed image data into a general rectangular image data format (step S101). In this way, the input image conversion unit 171 is an image conversion unit that converts the shear-deformed image data into general rectangular image data.

After the process of step S101, the image adjustment circuit 170 executes image processing of local dimming. The image processing of local dimming will be described below with reference to FIG. 24. After the process of step S101, the lighting amount calculation unit 172 determines the lighting amount of each LED (step S102). After the process of step S102, the luminance distribution calculation unit 175 selects a pixel of the display panel to be subjected to gradation correction (step S103). If there is no pixel to be selected in step S103 and all pixels have been processed and completed (step S104; Yes), the luminance distribution calculation unit 175 ends the image processing of local dimming. If there is a pixel to be selected in step S103 and all pixels have not been processed and completed (step S104; No), the luminance distribution calculation unit 175 proceeds to the process of step S105. For the pixel selected in step S103, the luminance distribution calculation unit 175 calculates the physical position of the pixel of the display panel taking into account the angle θg (step S105). The luminance distribution calculation unit 175 calculates the backlight luminance at the physical pixel position of the pixel calculated in step S105 (step S106). The gradation value correction unit 174 performs gradation correction of the pixel according to the backlight luminance calculated in step S106 (step S107). Next, the image adjustment circuit 170 performs the process of step S103 to process other pixels. In this way, each pixel reflects a gradation value that has been corrected as necessary, taking into account the angle θg.

As described above, the display device of the twelfth embodiment includes a display panel 110 having a display area 111, a backlight IL superimposed on the display area 111, and an image adjustment circuit 170. The display panel 110 includes an array substrate SUB1, a plurality of pixels Pix provided in the display area 111 of the array substrate SUB1, a plurality of scanning lines GL extending in the direction Vss, and a plurality of signal lines SL extending in the direction Vsl. The direction Vss is non-parallel and non-orthogonal to a direction perpendicular to the direction Vsl. In contrast, the backlight IL has a plurality of light-emitting elements 516 at a position overlapping the display area 111 in a planar view, and includes a light-emitting element output signal line LSL extending in the direction Vsl (direction Vy) and connected to the light-emitting element 516, and a light-emitting element scanning line LGL extending in a direction Vx perpendicular to the direction Vsl (direction Vy) and connected to the light-emitting element 516.

Furthermore, the image adjustment circuit 170 reduces the effect of the angle θg between the extension direction of the light-emitting element scanning line LGL and the extension direction of the scanning line GL, making the lighting amount of the partial light-emitting area PLA for the pixel Pix appropriate, and performing effective local dimming control of the backlight IL.

(Embodiment 13)
In the thirteenth embodiment, an example of a backlight IL (see FIG. 8) will be described. FIG. 25 is a block diagram showing an example of a configuration of a display system according to the thirteenth embodiment. Unlike the backlight IL (see FIG. 23) of the twelfth embodiment, the backlight IL (FIG. 25) of the thirteenth embodiment has a light-emitting element scanning line LGL for selecting a light-emitting element extending in the Vss direction. The display system in the thirteenth embodiment shown in FIG. 25 differs from that in FIG. 22 in that it does not have an input image conversion unit 171. The same components as those in the above-mentioned embodiments are given the same reference numerals, and duplicated descriptions will be omitted.

As shown in FIG. 27, the backlight IL has light-emitting element scanning lines LGL that select light-emitting elements extending in the Vss direction, and light-emitting output signal lines LSL that extend in the Vy direction perpendicular to the Vx direction. The light-emitting element scanning lines LGL extend in the Vss direction. In the backlight IL, a light-emitting element 516 is arranged in an area surrounded by the light-emitting output signal lines LSL and the light-emitting element scanning lines LGL. As a result, one partial light-emitting area PLA becomes a parallelogram.

The direction in which the light-emitting element scanning line LGL extends is parallel to the direction in which the scanning line GL extends. Therefore, the scanning line GL is not inclined with respect to the light-emitting element scanning line LGL. This ensures that the amount of light emitted by the light-emitting element 516 matches the brightness of the pixel Pix in the display area 111 that it actually overlaps.

The light-emitting elements 516 in the partial light-emitting region PLB of the light-emitting region 511, which does not overlap with the display region 111 in a plan view, may be removed to form a dummy region that does not emit light. When the light-emitting elements 516 are in the partial light-emitting region PLB, the load currents of the light-emitting output signal lines LSL and the light-emitting element scanning lines LGL become uniform, and the variation in the characteristics of the light-emitting elements 516 depending on the location is reduced.

As described above, the display device of embodiment 13 includes a display panel 110 having a display area 111 and a backlight IL superimposed on the display area 111. The display panel 110 includes an array substrate SUB1, a plurality of pixels Pix provided in the display area 111 of the array substrate SUB1, a plurality of scanning lines GL extending in the direction Vss, and a plurality of signal lines SL extending in the direction Vsl. The direction Vss is non-parallel and non-orthogonal to a direction perpendicular to the direction Vsl. In contrast, the backlight IL has a plurality of light-emitting elements 516 at a position overlapping the display area 111 in a planar view, and includes a light-emitting element output signal line LSL extending in the direction Vsl (direction Vy) and connected to the light-emitting element 516, and a light-emitting element scanning line LGL extending in the direction Vss and connected to the light-emitting element 516. This makes the extension direction of the light-emitting element scanning line LGL parallel to the extension direction of the scanning line GL, reducing the effect of the angle θg described above. As a result, the lighting amount of the partial light-emitting area PLA for the pixel Pix becomes appropriate, and effective local dimming control is performed on the backlight IL.

The pixel positions of the display panel can be easily calculated by having a gradient of θg in the backlight IL as well. Therefore, in the thirteenth embodiment, the input image conversion unit 171 as in the twelfth embodiment is not necessary.

The display system of embodiment 13 shown in FIG. 25 is different from the display system of embodiment 12 shown in FIG. 22 in that the configuration of the image adjustment circuit 170 is different, but other parts other than the configuration of the image adjustment circuit 170 are the same. However, the optical profile data used for calculation is different from the optical profile in general Cartesian coordinates. The optical profile is data that indicates how the brightness of the backlight emission unit spreads within the display surface as the backlight brightness, and is necessary for calculating the distribution of the backlight brightness. In this embodiment, since the light source is arranged at an angle, if the system of FIG. 25 is configured based on Cartesian coordinates, the optical profile needs to be corrected.

Figure 26A is a schematic diagram showing optical profile data of a backlight before conversion when calculating the illumination amount of the backlight according to the thirteenth embodiment. Figure 26B is a schematic diagram showing optical profile data of a backlight after conversion when calculating the illumination amount of the backlight according to the thirteenth embodiment. freal (Vx, Vy) shown in Figure 26A is an optical profile showing the propagation range of the light emitted by one light-emitting element 516 at (Vx, Vy) = (0, 0). The scanning line GL extends in the direction Vss, and there is an angle θg between the direction Vx and the direction Vss. Therefore, the pixel Pix is treated as a parallelogram. When the pixel Pix of the parallelogram is converted into the pixel GPix of the orthogonal lattice treated in the image data, the optical profile freal (Vx, Vy) is converted into an optical profile fsystem (Xs, Ys) (see Figure 26B) in the orthogonal coordinate system where the direction Xs and the direction Ys are at right angles.

In the display system of embodiment 13, the coordinates of the image data are converted into orthogonal coordinates in which the pixel Pix is an orthogonal grid and the direction Xs and the direction Ys form a right angle, using the following formulas (1) and (2). Here, the tilt k is calculated using formula (3). These formulas (1) to (3) are stored in advance in the image adjustment circuit 170 as a converted optical profile.

As shown in FIG. 26B, the image data is expressed in orthogonal grid coordinates, so the illumination amount calculation unit 172 calculates the illumination amount using the optical profile fsystem(Xs, Ys), and the correct luminance can be calculated even if the calculation is performed on the assumption that the shear-deformed image data is arranged on orthogonal coordinates. The illumination amount calculation unit 172 sends the calculated illumination amount data Dla and light source synchronization signal Dsync to the light source control circuit 512.

The luminance distribution calculation unit 175 calculates the luminance distribution for each pixel Pix that overlaps with the illumination amount of one partial light-emitting area PLA calculated using the optical profile fsystem(Xs, Ys). The gradation value correction unit 174 corrects the gradation value of each pixel Pix of the image data based on the luminance distribution calculated by the luminance distribution calculation unit 175, and sends corrected image data Di including the corrected gradation values to the display control circuit 112.

As described above, the image adjustment circuit 170 converts the image coordinates with the direction Vsl (direction Vy) as the first axis and the direction Vss as the second axis into image coordinates with the direction Vsl (direction Vy) as the first axis and the direction Vx perpendicular to the direction Vsl (direction Vy) as the second axis, and calculates the illumination level of each light-emitting element 516. This reduces the influence of the angle θg between the extension direction of the light-emitting element scanning line LGL and the extension direction of the scanning line GL. As a result, the illumination level of the partial light-emitting area PLA for the pixel Pix becomes appropriate, and effective local dimming control is performed on the backlight IL.

Although the above describes a preferred embodiment, the present disclosure is not limited to such an embodiment. The contents disclosed in the embodiment are merely examples, and various modifications are possible without departing from the spirit of the present disclosure. Appropriate modifications made without departing from the spirit of the present disclosure naturally fall within the technical scope of the present disclosure.
