In this application, the electronic device 10 may be an electronic device based on concepts such as Virtual Reality (VR), Augmented Reality (AR), Mixed Reality (MR), and Mediated Reality (MR). equipment. Among them, the implementation of virtual reality is generally based on pure virtual digital images (for example, a virtual scene is generated by the image source 142 mentioned later), and the implementation of augmented reality and mixed reality is generally based on virtual digital images and naked-eye reality (for example, by The human eye acquires the real scene), and the implementation of mediated reality is generally based on virtual digital images and digital reality (for example, the real scene is acquired by an additional camera on the device). Furthermore, since such electronic devices need to provide users with a different visual experience, their overall structure can be head-mounted, glasses-type, etc. Based on this, this embodiment provides an exemplary explanation by taking the electronic device 10 as AR glasses as an example. Of course, in some other embodiments, the electronic device 10 may also be a terminal device with a display screen, such as a smart phone or a smart watch.

The number of the temple assemblies 12 may be two, and one end of the two temple assemblies 12 may be movably connected to the two ends of the spectacle frame assembly 11 through the rotating shaft assembly 13 respectively. Further, the optical-mechanical module 14 can be connected to the frame assembly 11 to provide a visual experience for the user. Corresponding exemplary descriptions are provided below.

As an example, the spectacle frame assembly 11 may include a front shell 111 and a back shell 112, which may be assembled and connected through one or a combination of assembly methods such as gluing, snapping, threaded connection, etc. At this time, the rear case 112 and the front case 111 can cooperate to form a storage cavity (not labeled in the figure) for placing the optical engine module 14 . Based on the implementation of augmented reality, the front case 111 can be provided with a first window 113, the rear case 112 can be provided with a second window 114, and the optical-mechanical module 14 can be between the first window 113 and the second window 114.

At this time, optical lenses can be provided at the first window 113 and/or the second window 114, so that at least the transmittance of light from the external environment can be controlled to increase the contrast between naked-eye reality and virtual digital images.

In addition, the optical-mechanical module 14, the motherboard 15, the battery 16 and other structural components are reasonably distributed within the frame assembly 11, the temple assembly 12 and other structural components, which can balance the weight distribution of the electronic device 10, thereby improving the The electronic device 10 is reliable and comfortable to wear.

As an example, the optical engine module 14 may include a base 141 and an image source 142, a first lens 143, and a second lens 144 assembled on the base 141. The relative positional relationship between the image source 142, the first lens 143 and the second lens 144 may be triangular. As an example, the above triangle may be an isosceles right triangle, with the first lens 143 located on its hypotenuse. Of course, a lens 145 can also be disposed between the image source 142 and the first lens 143 to facilitate image focusing. 2 , when the optical engine module 14 is assembled with the frame assembly 11 , the base 141 can be assembled and connected with the front case 111 and/or the rear case 112 , the first lens 143 is close to the second window 114 , and the second lens 144 is close to First window 113.

Further, based on the implementation of augmented reality, the image source 142 can be a display screen such as LCD (Liquid Crystal Display), or a display screen such as OLED (Organic Light-Emitting Diode) or QLED (Quantum Dot Light Emitting Diode). , it can also be a display screen such as Mini-LED or Micro-LED to provide the required virtual digital picture; the first lens 143 can be a beam splitter, which has corresponding reflection value and transmission value (R1/T1); The second mirror 144 can be a concave mirror, which also has corresponding reflection values and transmission values (R2/T2). 3, for the virtual digital picture generated by the image source 142, the propagation path of the light can be: the light emitted by the image source 142 is projected to the first lens 143, and the light is partially reflected by the first lens 143 with a percentage of R1.

For light from the external environment, the propagation path of the light may be: the light passes through the second lens 144 at a percentage of T2, and further propagates to the first lens 143; this part of the light passes through the first lens 143 at a percentage of T1 And be received by the user's eyes.

Referring to FIGS. 4 to 6 together, FIG. 4 is a schematic structural diagram of an embodiment of a pixel arrangement structure in a display device provided by this application. FIG. 5 is a schematic structural diagram of an embodiment of a pixel arrangement structure in a display device provided by this application. FIG. 6 This is a screen presented by an embodiment of the electronic device provided by this application. It should be noted that the pixels framed by the dotted lines in Figures 4 and 5 can constitute the smallest repeating unit (that is, the basic pixel unit) in the pixel arrangement structure. For example, the basic pixel unit in Figure 4 is RGBG, and for example, the basic pixel unit in Figure 5 The pixel unit is RGB. In other words, the pixel arrangement structure includes repeated arrangement of basic pixel units, and the basic pixel unit is defined as the smallest repeating unit of all pixels in the pixel arrangement structure.

Generally, with reference to Figure 12, the display device may include a stacked substrate (Substance, abbreviated as Sub), a pixel drive circuit (Pixel Drive Circuit, PDC), a pixel arrangement structure, a pixel drive circuit and a pixel electrically connected to the pixel drive circuit. The pixel arrangement structure emits light under the control of the pixel driving circuit, or the pixel arrangement structure presents corresponding colors when the pixel driving circuit controls the deflection of liquid crystal molecules, thereby allowing the display device to display a picture. For displays such as OLED, the display device may include an anode and a cathode electrically connected to the pixel driving circuit, and a luminescent material between the anode and the cathode that emits visible light of a certain color under the action of carriers; for example Three luminescent materials that respectively emit red (R), green (G) and blue (B) light are distributed according to certain rules. The luminescent materials corresponding to two adjacent pixels are separated by a Pixel Define Layer (PDL). , so that the display device is divided into corresponding pixel arrangement structures based on the distribution rules of the luminescent material. For displays such as LCDs, the display device may include a liquid crystal electrically connected to the pixel drive circuit, and a color filter located on one side of the liquid crystal; the liquid crystal molecules are deflected under the action of an electric field, and the color filter has a pattern according to certain rules. Color blocks of red (R), green (G) and blue (B) are distributed, and the color blocks corresponding to two adjacent pixels are separated by a black matrix (Black Matrix, BM), so that the display device is based on the color The distribution rules of the blocks divide the corresponding pixel arrangement structure. Among them, when viewed along the light emitting direction of the display device, the pixel definition layer and the black matrix generally form a grid to form multiple pixels spaced apart from each other; different pixels in the pixel arrangement structure correspond to different drains in the pixel drive circuit one by one, so that Each pixel can be individually controlled by the pixel driving circuit. It should be noted that the pixel driving circuit, pixel arrangement structure and other structures are well known to those skilled in the art, and will not be described in detail here.

Generally, with reference to Figure 11, for a typical 7T1C pixel driving circuit, the pixel control circuit may include seven transistors (such as T1, T2, ... and T7) and a storage capacitor Cst. Among them, the first transistor T1 is a driving transistor; the gates of the second transistor T2, the third transistor T3 and the seventh transistor T7 are connected to the scanning signal of the current stage (for example, Scan2 and Scan3), and the gate of the fourth transistor T4 is connected to For the upper-level scanning signal Scan1, the source of the fourth transistor T4 is connected to the source of the third transistor T3, and the drain of the fourth transistor T4 is connected to the source of the seventh transistor T7 and the reference voltage Vref respectively. Furthermore, the functions of the 7T1C pixel control circuit can be divided into a reset phase S1, a compensation phase S2 and a light emitting phase S3.

In the reset phase S1, the scanning signal Scan1 of the previous level is low level, and the scanning signal (such as Scan2 and Scan3) of this level and the luminescence signal EM are high level, so the fourth transistor T4 is turned on, causing the first transistor The gate of T1 is reset to the reference level Vref.

In the voltage compensation phase S2, the luminescence signal EM is also high level, while the scanning signal Scan1 of the previous level becomes high level, and the scanning signal of this level (such as Scan2 and Scan3) becomes low level, so the second level The transistor T2 is turned on, so that the source of the first transistor T1 is connected to the data signal Data. At this time, since the gate and drain of the first transistor T1 are short-circuited, the first transistor T1 forms a diode structure. Based on this, after the source of the first transistor T1 is connected to the data signal Data, the gate of the first transistor T1 The pole will be charged to the first potential (Vdata-Vth). Wherein, Vdata is the level of the data signal Data, and Vth is the threshold voltage of the first transistor T1. In other words, the level of the gate of the first transistor T1 will be equal to the difference between the level of the data signal Data and the threshold voltage of the first transistor T1. At the same time, the third transistor T3 and the seventh transistor T7 are also connected to low-level scanning signals (such as Scan2 and Scan3), so the seventh transistor T7 is turned on, causing the anode of the organic light-emitting diode to be reset to the reference level Vref. .

In the light-emitting stage S3, the light-emitting signal EM is low level, and the scanning signal Scan1 of the previous level and the scanning signal (such as Scan2 and Scan3) of this level are both high level. Therefore, the second transistor T2, the third transistor T3, Neither the fourth transistor T4 nor the seventh transistor T7 is conductive, and the voltage source ELVDD is transmitted to the anode of the organic light-emitting diode through the first transistor T1, the fifth transistor T5, and the sixth transistor T6, and then forms a loop with the common ground terminal ELVSS, so that Organic light-emitting diodes emit light.

The inventor of this application discovered during long-term research and development work that: for OLED display screens, such as Figure 4, the pixel gap is generally at the level of 10 to 20 μm; for LCD display screens, such as Figure 5, the pixel gap is generally between 5 and 20 μm. 10μm level. Among them, the pixel gap can be defined as the minimum distance between any two of R, G, and B pixels. Obviously, the larger the pixel gap, the more serious the screen door effect and graininess of the display. Due to the large differences in application scenarios, this level of pixel gap may be tolerated for terminal devices such as smartphones and smart watches, but it is intolerable for terminal devices such as VR glasses and AR glasses. For example, Figure 6 The picture shown has obvious screen door effect and graininess. Specifically, regardless of whether the image source 142 is a display screen such as an OLED or a display screen such as an LCD, the optical path of the light emitted by the image source 142 changes under the action of the first lens 143, the second lens 144 and the lens 145, and the user The picture you see may have a more serious screen door effect and graininess, which can simply be regarded as the pixel gap being enlarged to a certain extent. For this reason, one of the original intentions of the invention of this application is: how to reduce the pixel gap of the display screen to improve the screen door effect and graininess, thereby improving the fineness of the display. However, a technical solution that those skilled in the art can easily think of is to increase the pixel density of the pixel arrangement structure (that is, the number of pixels per unit area) to make the pixels more compact, thereby improving the screen door effect and graininess; but this also This will cause the number of scanning lines, data lines, thin film transistors, storage capacitors and other structures in the pixel driving circuit to increase exponentially, causing the production cost of the pixel driving circuit to rise sharply.

Referring to Figures 7 to 10 together, Figure 7 is a schematic structural diagram of an embodiment of a basic pixel unit in the pixel arrangement structure provided by this application. Figure 8 is a schematic structural diagram of an embodiment of a basic pixel unit in the pixel arrangement structure provided by this application. FIG. 9 is a schematic structural diagram of an embodiment of a basic pixel unit in the pixel arrangement structure provided by this application. FIG. 10 is a schematic structural diagram of an embodiment of a basic pixel unit in the pixel arrangement structure provided by this application.

7 to 10 , each basic pixel unit 100 may include a first pixel 101 with a first color, a second pixel 102 with a second color, and a third pixel 103 with a third color. The first pixel 101, The number of at least two of the second pixels 102 and the third pixels 103 is equal. Wherein, the first color, the second color and the third color may be any one of red (R), green (G) and blue (B) respectively, and each of them is different. Of course, each basic pixel unit 100 may also include a fourth pixel with a fourth color, for example, the fourth color is white. For the convenience of description, this embodiment takes the first pixel 101 as red, the second pixel 102 as green, and the third pixel 103 as blue as an example for exemplary description. Further, at least one of the first pixel 101, the second pixel 102 and the third pixel 103 may include at least two corresponding sub-pixels, that is, split the original pixel into multiple, so that the original pixel gap is filled by more Pixel occupation is used to reduce the pixel gap with less (or even no) expansion of the basic pixel unit, making the pixel arrangement more compact, which is beneficial to improving the screen door effect and graininess, and improving the fineness of the display. In addition, compared with increasing the pixel density of the pixel arrangement structure, in this application, at least two sub-pixels of the same pixel still correspond to the original drain electrode in the pixel driving circuit, without the need to add additional thin film transistors and other components such as scanning lines and data lines. , storage capacitors and other related structures, thereby less (or even no) changes to the original pixel drive circuit, thereby controlling the manufacturing cost of the pixel drive circuit. Among them, the first pixel 101, the second pixel 102 and the third pixel 103 may be in a rectangular, rhombus or other shapes, and the corresponding sub-pixels may also be in a rectangular, rhombus or other shapes.

In some embodiments, such as FIGS. 7 to 9 , the numbers of the first pixels 101 and the third pixels 103 may be equal, and may not be equal to the number of the second pixels 102 , for example, the number of the second pixels 102 is equal to the first pixels. The sum of the number of 101 and the number of third pixels 103. Among them, for displays such as OLED, because there are certain differences in the lifespans of the three luminescent materials that emit red (R), green (G) and blue (B) light, the areas of the three luminescent materials have certain differences. difference. For example, among the RGB pixels, the B pixel (that is, the luminescent material corresponding to the blue light emitting material) has the relatively shortest life, and the area of the B pixel (such as the third pixel 103) is also relatively largest, which is beneficial to increasing the reliability of the display device.

In some other embodiments, such as FIG. 10 , the numbers of the first pixels 101 , the second pixels 102 and the third pixels 103 may be equal. Among them, for LCD display screens, since they do not rely on luminescent materials, the areas of color blocks with red (R), green (G) and blue (B) colors can be equal, that is, the areas of RGB pixels can be equal.

Further, with reference to FIG. 7 , in each basic pixel unit 100 , one of the first pixel 101 , the second pixel 102 and the third pixel 103 may include at least two corresponding sub-pixels. For example, the second pixel 102 may include at least two corresponding sub-pixels. the second sub-pixel 1021; or, with reference to FIG. 8, the first pixel 101, the second pixel 102 and the third pixel 103 may each include at least two corresponding sub-pixels. For example, the first pixel 101 includes at least two first pixels. The sub-pixel 1011 and the second pixel 102 include at least two second sub-pixels 1021; or, with reference to FIG. 9 or FIG. 10, the first pixel 101, the second pixel 102 and the third pixel 103 may respectively include corresponding at least two sub-pixels.

As an example, with reference to Figure 9 or Figure 10, in each basic pixel unit 100, the first pixel 101 may include at least two first sub-pixels 1011, and the second pixel 102 may include at least two second sub-pixels 1021. The third pixel 103 may include at least two third sub-pixels 1031 so that more pixel gaps are occupied by pixels to reduce the pixel gap as much as possible with less (or even no) expansion of the basic pixel unit, such that The pixel arrangement is more compact, which helps to improve the screen door effect and graininess, and improves the fineness of the display. Among them, the geometric center of the same pixel in the first pixel 101, the second pixel 102 and the third pixel 103 remains unchanged before and after separation. Further, the sub-pixels can be evenly distributed around the geometric center of the pixel where they are located. For example, at least two first sub-pixels 1011 are evenly distributed around the geometric center (such as end point C) of the first pixel 101. For example, at least two third sub-pixels 1031 are evenly distributed around the geometric center (for example, endpoint E) of the third pixel 103, which is beneficial to increasing the uniformity of the pixel arrangement structure and reducing the difficulty of manufacturing. Combining Figure 9 and Figure 4, taking the first pixel 101 as an example, the geometric center of the first pixel 101 before separation can be the end point C; subsequently, the first pixel 101 can be divided into four first sub-pixels 1011, and four first sub-pixels 1011. The line connecting the geometric center of one sub-pixel 1011 can be a quadrilateral, and the geometric center of the quadrilateral can also be the end point C. In this case, the four first sub-pixels 1011 can be evenly distributed around the end point C.

Further, the number of at least two of the first sub-pixels 1011 in each first pixel 101, the second sub-pixels 1021 in each second pixel 102, and the third sub-pixels 1031 in each third pixel 103 It can be equal to make the pixel arrangement more uniform when the pixel arrangement is compact, and to take into account the production cost of the display device. For example, the number of first sub-pixels 1011 is equal to the number of third sub-pixels 1031 and is greater than the number of second sub-pixels 1021. This is conducive to simplifying the pixel arrangement structure and thereby reducing the manufacturing cost of the display device.

In some embodiments, such as Figure 9, the area of the second sub-pixel 1021 among the first sub-pixel 1011, the second sub-pixel 1021 and the third sub-pixel 1031 is the smallest, and the number of the second sub-pixel 1021 is equal to the first sub-pixel 1011 The sum of the number of and the number of the third sub-pixel 1031. In this way, for the pixel arrangement structure shown in Figure 4, the pixel arrangement structure shown in Figure 9 splits each of the original pixels into multiple ones, so that the original pixel gaps are occupied by more pixels, so that less ( Even if the basic pixel unit is not expanded, the pixel gap should be reduced as much as possible to make the pixel arrangement more compact, which will help improve the screen door effect and graininess, and improve the fineness of the display. Among them, the number of the first sub-pixel 1011, the second sub-pixel 1021 and the third sub-pixel 1031 can be two, three, or four respectively, etc.; all first sub-pixels 1011 correspond to pixel driving circuits One drain of the second sub-pixel 1021 corresponds to the other drain of the pixel driving circuit, and all the third sub-pixels 1031 correspond to the other drain of the pixel driving circuit. In this way, at least two sub-pixels of the same pixel still correspond to the original drain in the pixel driving circuit, without adding additional thin film transistors and other related structures such as scanning lines, data lines, storage capacitors, etc., resulting in less (or even no) changes. original pixel driving circuit, thereby controlling the manufacturing cost of the pixel driving circuit.

Further, in each basic pixel unit 100, the number of the first pixel 101 and the third pixel 103 may be one respectively, and the number of the second pixels 102 may be two, that is, the number of the second pixels 102 in each basic pixel unit 100 may be one. The number is twice that of the first pixel 101 and the third pixel 103 respectively, which is beneficial to ensuring the uniform distribution of the first pixel 101, the second pixel 102 and the third pixel 103, and at the same time ensuring that the pixel area of the second pixel 102 is the largest. , to extend its life. Based on this, the geometric center of the first pixel 101, the geometric center of the third pixel 103 and the geometric center of a second pixel 102 form a first isosceles right triangle (for example, ΔCDE), and the geometric center of the third pixel 103 and The line connecting the geometric centers of the two second pixels 102 forms a second isosceles right triangle (for example, ΔDEF). The second isosceles right triangle and the first isosceles right triangle share a right-angled side (for example, the line segment DE). The hypotenuse of the waist right triangle (eg line segment DF) is parallel to the hypotenuse of the first isosceles right triangle (eg line segment CE). 9, the geometric center of any one of the first pixel 101, the second pixel 102, and the third pixel 103 can be defined as the geometric center of the figure surrounded by the lines connecting the geometric centers of the corresponding at least two sub-pixels. For example, the geometric center of the first pixel 101 is the geometric center of the quadrilateral (such as the end point C) surrounded by the lines connecting the geometric centers of the four first sub-pixels 1011. For example, the geometric center of the third pixel 103 is the geometric center of the four first sub-pixels 1011. The geometric center (for example, endpoint E) of the quadrilateral formed by the lines connecting the geometric centers of the three sub-pixels 1031. In this way, the geometric centers of the first pixel 101 and the third pixel 103 can be located on the same horizontal line, and the geometric centers of the two sets of second pixels 102 can also be located on the same horizontal line; the geometric centers of the adjacent first pixel 101 and the second pixel 102 The line connecting the geometric centers of the adjacent third pixel 103 and the second pixel 102 is inclined 45° or 135° relative to the horizontal line, which is beneficial to increasing the uniformity of the pixel arrangement structure. , and reduce the difficulty of manufacturing the display device.

Similarly, among the first sub-pixel 1011, the second sub-pixel 1021 and the third sub-pixel 1031, the third sub-pixel 1031 has the largest area to extend the life of the third sub-pixel 1031, which is beneficial to increasing the reliability of the display device.

Further, with reference to Figures 11 and 12, for displays such as OLED, the sub-pixels of the same pixel in the first pixel 101, the second pixel 102 and the third pixel 103 can be connected to the pixel driving circuit through corresponding via structures. , for example, the anodes corresponding to the sub-pixels of the same pixel are connected to the same drain of the pixel driving circuit through corresponding via structures, that is, the sub-pixels of the same pixel (for example, the four first sub-pixels 1011 of the first pixel 101) The pixel driving circuit is connected in parallel (for example, between the common ground terminal ELVSS and the drain of the sixth transistor T6 in the 7T1C pixel driving circuit). In other words, when each pixel is powered on (or powered off), all sub-pixels of the pixel are powered on (or powered off), and then all emit light (or do not emit light). With reference to Figure 4, two adjacent luminescent materials are separated by a pixel definition layer, that is, adjacent pixels are separated by a pixel definition layer. Similarly, in FIGS. 7 to 9 , the luminescent materials corresponding to adjacent sub-pixels in the same pixel can be separated by a pixel definition layer, that is, the sub-pixels of the same pixel can be separated by a pixel definition layer. In addition, in Figures 7 to 9, the luminescent materials corresponding to adjacent sub-pixels in the same pixel can also be separated by anodes, that is, the sub-pixels of the same pixel can be separated by anodes. In short, the sub-pixels of the same pixel in the first pixel 101, the second pixel 102 and the third pixel 103 are separated by the intermediate body 104, which may be an anode or a pixel defining layer of the display device. It is worth noting that compared to the pixel definition layer (usually an insulator), the sub-pixels of the same pixel are separated by anodes, which is beneficial to reducing the impact of each sub-pixel in the same pixel with respect to the pixel drive circuit electrically connected to the pixel. The potential difference between the drains reduces the difference in impedance, thereby increasing the consistency of the light emission of sub-pixels of the same pixel, thereby increasing the uniformity of light output from the display device.

In some other embodiments, such as Figure 10, the areas of the first sub-pixel 1011, the second sub-pixel 1021 and the third sub-pixel 1031 may be equal, and the areas of the first sub-pixel 1011, the second sub-pixel 1021 and the third sub-pixel 1031 The quantities can also be equal. In this way, it is beneficial to increase the uniformity of the pixel arrangement structure and reduce the difficulty of production. In addition, for the pixel arrangement structure shown in Figure 5, the pixel arrangement structure shown in Figure 10 splits each of the original pixels into multiple ones, so that the original pixel gaps are occupied by more pixels, so that in less ( Even if the basic pixel unit is not expanded, the pixel gap should be reduced as much as possible to make the pixel arrangement more compact, which will help improve the screen door effect and graininess, and improve the fineness of the display.

The difference with displays such as OLED is that for displays such as LCD, the color blocks corresponding to adjacent sub-pixels in the same pixel can be separated by a black matrix, that is, the sub-pixels of the same pixel can be separated by a black matrix. Therefore, at least two sub-pixels of the same pixel still correspond to the original drain in the pixel driving circuit, without adding additional thin film transistors and other related structures such as scanning lines, data lines, storage capacitors, etc., resulting in less (or even no) changes. original pixel driving circuit, thereby controlling the manufacturing cost of the pixel driving circuit.
