The screen-door effect (screen-door effect) means that human eyes can directly see pixel points of a display screen due to insufficient resolution of the display screen in current display equipment such as electronic equipment and virtual reality head-mounted equipment, and the screen-door effect is the same as what the human eyes see after passing through a screen window. The Black area in these screens is called Black Matrix (BM), where the Black Matrix is a Black grid formed on one side of a color film substrate in a liquid crystal display panel and used to divide adjacent color resists, block color gaps, and prevent light leakage or color mixing. However, the display screen of the electronic device may generate fine line waving caused by rendering the image in real time and separate flickering (sharp flicker) at high contrast edges due to too low pixel density, so that the user can see the pixels and the black matrix between the pixels, which affects the display effect of the image on the display screen.
The display device and the display method provided by the embodiment of the present application are described in detail below with reference to fig. 1 to 10 through specific embodiments and application scenarios thereof.
Fig. 1 is a schematic structural diagram of a display device according to an embodiment provided in the present application.
Referring to fig. 1, the display device includes a backlight module 101, a display panel 102, and an optical device 103. The optical device 103 is arranged between the backlight module 101 and the display panel 102, and the optical device 103 is used for changing the light ray direction of part of light rays from the backlight module 101 to the display panel 102; the offset between the first pixel 1041 projected on the display panel 102 by the light with the light direction changed by the optical device 103 and the second pixel 1042 projected on the display panel 102 by the light with the light direction unchanged is smaller than or equal to a preset offset, the first pixel at least partially coincides with a target area between at least two adjacent second pixels on the display panel, and the first pixel is used for covering a target area in the display panel which is not luminous.
So, can be under the condition of the pixel density that does not change the display screen, can pass through optical device, make the light of a light spot emission of backlight unit, present two at least pixel in display panel, thereby the luminous part of pixel in the display panel has been increased, and make the offset between first pixel and the second pixel be less than or equal to and predetermine the offset, make the luminous part of pixel hide luminous portion in the display panel like first pixel, so that the black matrix is invisible, the granular sensation that the black matrix caused the image has been improved, the screen window effect has been reduced, so, can promote the effect that the image appears in the display device display screen.
It should be noted that the material of the optical device in the embodiment of the present application is an optical material having light transmittance and refractive index, wherein the optical material may include optical glass, optical crystal, or optical plastic. Specifically, the optical device made based on the above optical material may be a liquid crystal lens or an optical glass plate. And, the display device in this embodiment of the application may include an electronic device, a Virtual Reality head-mounted device, a wearable device, and the like, which have a display function, where the electronic device is such as a mobile phone, a tablet computer, and the like, the Virtual Reality head-mounted device is such as Virtual Reality (VR) glasses, a VR game helmet, and the like, and the wearable device is such as a smart watch, smart glasses, and the like.
In the embodiment of the present application, there are four forms for changing the offset, and the following describes the display device based on different connection forms of the backlight module 101, the display panel 102, and the optical device 103.
In one possible or more possible embodiments, the display device further includes a first driving layer;
the first driving layer is connected with the optical device and used for driving the optical device to rotate axially.
Illustratively, as shown in fig. 2, the optical device 103 may be an optical glass plate in this example, in this case, the first driving layer 105 may support the backlight module 101 and the display panel 102 such that a receiving cavity is formed between the backlight module 101 and the display panel 102, the receiving cavity is used for receiving the optical device 103, here, the first driving layer 105 is connected with the optical device 103, and the first driving layer 105 drives the optical device 103 to rotate axially by an angle, such as θ, in the receiving cavity. Thus, the position relationship between the optical device 103 and the display panel 102 relative to the backlight module 101 can be changed, so as to adjust the light direction emitted by the backlight module 10, emitted through the optical device 103, and projected onto the display panel 102, and thus, the light projected by the optical device 103 after changing the light direction is projected on the first pixel point 1041 on the display panel 102, and the light projected by the light without changing the light direction is projected on the second pixel point 1042 on the display panel 102, so that the light emitting portion of the pixels in the display panel is increased without changing the pixel density of the display screen.
Based on the above structure, the embodiment of the present application describes in detail a display method provided by the embodiment of the present application with reference to fig. 3.
Fig. 3 is a flowchart of a display method according to an embodiment of the present application.
As shown in fig. 3, the display method may include the steps of:
Illustratively, referring to fig. 2, the optical glass plate is tilted along the axis by the x-axis and the y-axis as shown in fig. 4, wherein the optical glass plate shown in fig. 2 is rotated by θ degrees along the x-axis, so that the position relationship of the optical device 103 relative to the backlight module 101 and the display panel 102 can be changed by the optical device rotated by θ degrees along the x-axis, thereby adjusting the direction of the light emitted by the backlight module 10, emitted through the optical device 103 and projected onto the display panel 102, so that the light emitted from one light spot of the backlight module presents at least two pixel points in the display panel, i.e. a first pixel point 1401 projected on the display panel by the light with the light direction changed by the optical device and a second pixel point 1402 projected on the display panel by the light with the light direction not changed by the optical device, so that the pixel light emitting portion is shielded from the black matrix by adding and translating the pixel points in one frame of image, thereby reducing the screen effect.
It should be noted that, as shown in fig. 5, because the black matrixes are visually overlapped by the binocular image of the left-eye pixel and the right-eye pixel at present, and the granular sensation of the image of the electronic device is enhanced, in order to weaken the granular sensation caused by the visual overlapping of the black matrixes, in the embodiment of the present application, the black matrix which is a target region between the non-luminous portion, i.e., the second pixel, and the second pixel, in the display panel, can be covered by the first pixel as large as possible, so as to adjust the offset Δ y between the first pixel 1401 and the second pixel 1402 to be smaller than or equal to the preset offset, so that the first pixel 1401 and the target region between at least two adjacent second pixels 1402 on the display panel are at least partially overlapped, so that the first pixel 1401 covers the non-luminous target region, i.e., the black matrix, in the display panel, so that at least a portion of the black matrix is covered, and the granular sensation caused by the visual overlapping of the black matrixes is weakened, based on this, Δ y can be calculated by the following formula (1), so that the first pixel 1401 can cover the maximum area of the black matrix.
Where θ is an axial rotation angle of the optical device, n is a refractive index of the optical device (in this example, the optical device is an optical glass plate), t is a thickness of the optical device, and Δ y is an offset between the first pixel point and the second pixel point.
Thus, Δ y may be preset, and t and n are known, so that the angle θ of the axial rotation of the adjusting optical device can be calculated by the formula (1), and the positional relationship between the optical device 103 and the display panel 102 relative to the backlight module 101 is changed, so as to adjust the direction of the light emitted by the backlight module 10, emitted through the optical device 103, and projected onto the display panel 102.
Therefore, by changing the position relationship between the optical device 103 and the backlight module 101 and the display panel 102, the light direction emitted by the backlight module 10, emitted through the optical device 103 and projected onto the display panel 102 is adjusted, so that the offset between the first pixel point 1041 projected on the display panel 102 by the light with the light direction changed by the optical device 103 and the second pixel point 1042 projected on the display panel 102 by the light with the light direction unchanged is smaller than or equal to the preset offset, the first pixel point at least partially coincides with the target area between at least two adjacent second pixel points on the display panel, and the first pixel point is used for covering the target area which does not emit light in the display panel.
In another possible or multiple possible embodiments, based on the above embodiments, as shown in fig. 7, if the screen refresh rate of the display device is 90Hz, the pixel points of a 1-frame image can be simulated by using the pixel points of a 4-frame image, and meanwhile, the pixel points of the 4-frame image are matched with the tilt of the optical device, as shown in fig. 7, the positional relationship between the optical device 103 and the backlight module 101 and the display panel 102 is adjusted along the x axis and the y axis shown in fig. 4, for example, the optical glass plate is turned over by θ degrees along the x axis toward the third direction, so as to obtain the pixel point B projected on the display panel 102, and similarly, the optical glass plate is turned over θ degrees along the y axis toward the fourth direction, so as to obtain the pixel point C projected on the display panel 102, and other pixel points are not repeated, so that the pixel points obtained at 4 positions projected on the display panel 102, that the pixel points a, the pixel point B, the pixel point C, and the pixel point D simulate 4 pixel points, so that the screen pixel density can be increased by 4 times as compared with the original screen refresh rate of the display device, and the screen tilt can be reduced by 360Hz, and the screen particle effect can be reduced. It should be noted that, in the embodiment of the present application, the screen refresh rate of the display device may be 90Hz, and the lowest screen refresh rate of the display device may also be 60Hz, so that, taking the screen refresh rate of the display device as 60Hz as an example, with reference to the manner shown in fig. 7, the screen refresh rate of the display device may be increased to 240Hz.
Therefore, by adjusting the position relation of the optical device relative to the backlight module and the display panel and matching with the screen refresh rate, the resolution is improved to improve the granular sensation caused by the black matrix, and the screen definition is improved.
In one or more possible embodiments, the display device in the embodiments of the present application further includes an electric field control module;
the electric field control module is used for regulating and controlling an electric field in the display equipment so as to change the refractive index distribution of the optical device, and the refractive index distribution is related to the light direction.
Specifically, the optical device may be a liquid crystal lens in this example, and thus, the display device may change its spatial effective refractive index distribution by adjusting an electric quantity, and adjusting an electric field in the display device, and thus, the adjustment is performed by the backlight module through a refractive index distribution different from that of the optical device, and the light direction emitted and projected to the display panel through the optical device, and thus, a first pixel point of light projection on the display panel after the optical device changes the light direction is made to coincide at least partially with a target area between at least two adjacent second pixel points on the display panel, and the first pixel point is used to cover a target area of non-light emission in the display panel.
Based on the above structure, the embodiment of the present application describes another display method provided by the embodiment of the present application in detail with reference to fig. 8.
Fig. 8 is a flowchart of another display method according to an embodiment of the present disclosure.
As shown in fig. 8, the display method may include the steps of:
Therefore, according to the preset electric field parameter, the refractive index distribution of the optical device is adjusted, and therefore, based on different refractive indexes of the optical device, the light direction of partial light from the backlight module to the display panel is adjusted, so that the first pixel point of light projected on the display panel after the light direction is changed is less than or equal to the preset offset, the offset between the first pixel point and the second pixel point of light projected on the display panel without changing the light direction is less than or equal to the preset offset, the target area between the first pixel point and at least two adjacent second pixel points on the display panel is at least partially overlapped, the first pixel point is used for covering the target area which does not emit light in the display panel, therefore, the light emitting part of pixels in the display panel can be increased under the condition that the pixel density of the display screen is not changed, the light emitting part of the pixels covers the light emitting part, so that the black matrix is invisible, the granular sensation of the black matrix to the image is improved, the screen window effect of the image in the display screen of the display device can be improved.
In still another possible or various possible embodiments, the display device may further include a second driving layer based on the electric field control module shown above; wherein,
the second driving layer is connected with the optical device and used for driving the optical device to move along a first direction towards the backlight module or a second direction towards the display panel, and the first direction and the second direction are opposite directions.
As shown in fig. 9, the optical device may also be a liquid crystal lens in this example, in the embodiment of the present application, through the electric field control module (not shown in the figure) and the second driving layer 106, the refractive index distribution of the optical device may be adjusted according to the preset electric field parameters through the electric field control module, and the positional relationship between the optical device and the display panel 102 may be changed through the second driving layer 106, so that the optical device moves along the first direction toward the backlight module 101 or the second direction toward the display panel 102, such that the offset between the first pixel point on the display panel where the light is projected after the light direction is changed and the second pixel point on the display panel where the light is projected without changing the light direction is smaller than or equal to the preset offset, the target area between the first pixel point and at least two adjacent second pixel points on the display panel at least partially coincides, the first pixel point is used for covering the target area in the display panel where light is not emitted, thereby increasing the portion of the pixel in the display panel without changing the pixel density of the display screen, so that the black matrix can be hidden, and the display effect of the display screen is improved, thereby reducing the image display effect of the display screen.
In addition, the optical device in the embodiment of the present application may be disposed inside the display device, or may be disposed outside the display device, as an external device of the display device, to increase a light emitting portion of the pixel in the display panel.
