Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1 is a diagram illustrating a terminal screen according to an exemplary embodiment. As shown in fig. 1, the terminal screen may include: a substrate 10 and a display layer 20 disposed on the substrate 10.

The display layer 20 is used to implement a display function of the terminal screen. In the disclosed embodiment, the display layer 20 includes a main display area 21 and an auxiliary display area 22. Both the main display area 21 and the sub display area 22 have a display function. The number of the auxiliary display areas 22 may be one or plural. In fig. 1, the number of the auxiliary display areas 22 is schematically illustrated as 1. Alternatively, the main display area 21 is a display area with a relatively large area in the display layer 20, and the auxiliary display area 22 is a display area with a relatively small area in the display layer 20, that is, the area ratio of the main display area 21 in the display layer 20 is larger than the area ratio of the auxiliary display area 22 in the display layer 20.

In the embodiment of the present disclosure, the display layer 20 includes two different types of display regions, namely, a main display region 21 and an auxiliary display region 22, but the main display region 21 and the auxiliary display region 22 are physically integrated, that is, the display layer 20 is an integrated structure, which is not divided into a plurality of mutually independent components. For example, the display layer 20 is provided on one integrated structure of the substrate 10, that is, the main display area 21 and the sub display area 22 are formed on one substrate. The substrate 10 may be made of a glass material, or may be made of a flexible material such as PI (polyimide), which is not limited in the embodiment of the disclosure.

If the display layer 20 includes a plurality of independent components, and the components are spliced to form the display layer 20, a certain gap is inevitably formed at the splicing position, and finally, a gap is formed between the display contents of the components, so that the display effect that the display contents of the whole display layer 20 are integrated and have no gap cannot be achieved.

However, in the embodiment of the present disclosure, since the main display area 21 and the auxiliary display area 22 are physically integrated, and there is no gap between the two, there is no gap between the display content of the main display area 21 and the display content of the auxiliary display area 22, so as to achieve the effect of displaying the entire display layer 20 with the display content integrated and without gap.

The main display area 21 may include a plurality of pixels, and the sub display area 22 may include a plurality of pixels. A pixel may include a plurality of sub-pixels each for emitting one color light, and the plurality of sub-pixels mix more colors by emitting different color single light. In general, a pixel includes three different color sub-pixels of R (red), G (green), and B (blue), that is, a pixel includes at least one red sub-pixel, at least one green sub-pixel, and at least one blue sub-pixel. The red sub-pixel refers to a sub-pixel emitting red monochromatic light, the green sub-pixel refers to a sub-pixel emitting green monochromatic light, and the blue sub-pixel refers to a sub-pixel emitting blue monochromatic light. Of course, in some other possible embodiments, a pixel may include only one color sub-pixel, for example, a pixel may include only R, G, B sub-pixels of any one color. Alternatively, a pixel may only include two color sub-pixels, for example, a pixel only includes R, G, B any two color sub-pixels. Alternatively, a pixel may comprise at least one other color sub-pixel, such as at least one white sub-pixel, in addition to at least one red sub-pixel, at least one green sub-pixel, and at least one blue sub-pixel. The present disclosure does not limit the color and the number of sub-pixels included in one pixel.

In the embodiment of the present disclosure, at least one of the plurality of pixel attributes of the main display area 21 and the sub display area 22 is different, and at least one of the pixel attributes is the same. Pixel attributes refer to attributes associated with a pixel, i.e., attributes determined by the pixel design. For example, the pixel attributes may include a pixel size, a resolution, a center-to-center distance of adjacent pixels, a pixel arrangement, a pixel structure, a pixel connection, a pixel shape, and the like. For the main display area 21 and the sub display area 22, some of the pixel attributes are the same, and some of the pixel attributes are different.

In the embodiment of the present disclosure, by designing that at least one of the plurality of pixel properties of the main display area 21 and the auxiliary display area 22 is different, the light transmission performance of the auxiliary display area 22 is made superior to that of the main display area 21, so that an optical device can be disposed below the auxiliary display area 22; meanwhile, at least one pixel attribute in the multiple pixel attributes of the main display area 21 and the auxiliary display area 22 is designed to be the same, the purpose is to enable the display effects of the main display area 21 and the auxiliary display area 22 to be close to each other as much as possible, improve the integrity of the display effect of the whole terminal screen, and avoid the difference of the display effects of the main display area 21 and the auxiliary display area 22 which are visible to naked eyes, so that the optical device under the screen can work normally on the premise of not sacrificing the display effect of the terminal screen or sacrificing the display effect of the terminal screen as little as possible.

In the embodiment of the present disclosure, the light transmittance is an index for measuring the light transmittance of the medium (such as the main display area 21 and the auxiliary display area 22 in the embodiment of the present disclosure). Optionally, the transmittance of the auxiliary display region 22 is greater than the transmittance of the main display region 21, and/or the light transmission quality of the auxiliary display region 22 is better than the light transmission quality of the main display region 21. The transmittance is a percentage of the luminous flux transmitted through a medium such as the main display area 21 and the auxiliary display area 22 in the embodiment of the present disclosure to the incident luminous flux. Transmittance may also be referred to as light transmittance. Light transmission quality refers to the quality of light transmitted through a medium (such as the primary display area 21 and the secondary display area 22 in the disclosed embodiment), and the characteristic parameters of light transmission quality include, but are not limited to, at least one of the following: haze, SFR (Spatial frequency response), MTF (Modulation Transfer Function), which corresponds to an index of sharpness of an image. In the embodiment of the present disclosure, the optical device may be disposed below the auxiliary display region 22, and since the transmittance and/or the light transmission quality of the auxiliary display region 22 are better, the operation performance of the optical device may be ensured to the greatest extent.

In addition, considering that the number of the auxiliary display regions 22 may be more than one, when the display layer 20 of the terminal screen includes a plurality of auxiliary display regions 22, the pixel attributes of the respective auxiliary display regions 22 may be the same, or there may be at least two auxiliary display regions 22 having different pixel attributes. In addition, the same or different pixel attributes of each auxiliary display area 22 and the main display area 21 may be the same or different, and this is not limited in the embodiment of the present disclosure. For example, it is assumed that the display layer 20 includes a main display area, an auxiliary display area a, and an auxiliary display B, different pixel attributes in the main display area and the auxiliary display area a include a pixel size, the same pixel attribute includes a resolution and a pixel structure, different pixel attributes in the main display area and the auxiliary display area B include a pixel size and a resolution, and the same pixel attribute includes a pixel structure. Of course, the above examples are merely illustrative and explanatory, and are not intended to limit the technical solution of the present disclosure.

In the embodiment of the present disclosure, the pixel control circuit of the auxiliary display area 22 is located outside the auxiliary display area 22. The pixel control circuit of the auxiliary display area 22 is used to perform display control on the pixels in the auxiliary display area 22, such as controlling the pixels in the auxiliary display area 22 to emit light. The pixel control circuit may include a TFT (Thin Film Transistor), a capacitor, and other components, and these components are used to realize the functions of switching control, pixel compensation, light emission driving, and the like of the pixel. The pixel control circuit can be connected with the pixels through the wires. In the embodiments of the present disclosure, the trace refers to a power line and/or a signal line for controlling pixel display. The power line is used for providing voltage for the pixel; the signal lines are used for providing control signals, such as luminance or gray scale, to the pixels, and may also be referred to as data lines.

For the auxiliary display region 22, each sub-pixel may have an independent pixel control circuit, or a plurality of sub-pixels may share the same pixel control circuit. If each sub-pixel has an independent pixel control circuit, each sub-pixel can be independently controlled, and the control is more flexible; if a plurality of sub-pixels share the same pixel control circuit, the number of pixel control circuits of the sub-display region 22 can be reduced to some extent.

Alternatively, the pixel control circuit of the sub display area 22 is located in the main display area 21. For example, the pixel control circuit of the auxiliary display area 22 may be disposed below the sub-pixels in the area where the main display area 21 is adjacent to the auxiliary display area 22. Of course, in some other possible embodiments, a part of the pixel control circuit of the auxiliary display area 22 may be located below the pixels of the auxiliary display area 22, and another part of the pixel control circuit may be located in the main display area 21, which is not limited in this disclosure. In addition, the size and the structure of the pixel control circuit in the auxiliary display area 22 may be the same as or different from those of the pixel control circuit in the main display area 21, and this is not limited in the embodiment of the present disclosure.

To sum up, in the technical solution provided in the embodiment of the present disclosure, at least one of the multiple pixel attributes of the main display area and the auxiliary display area is designed to be different, so as to make the light transmittance of the auxiliary display area better than that of the main display area; meanwhile, at least one pixel attribute in the multiple pixel attributes of the main display area and the auxiliary display area is designed to be the same, the purpose is to enable the display effects of the main display area and the auxiliary display area to be close to each other as much as possible, the integrity of the display effect of the whole terminal screen is improved, and the difference that the display effects of the main display area and the auxiliary display area are visible to naked eyes is avoided, so that the optical device under the screen can normally work on the premise that the display effect of the terminal screen is not sacrificed or is sacrificed as little as possible.

In addition, by disposing the light emission control devices of the sub-pixels in the auxiliary display area outside the auxiliary display area, the light transmittance of the auxiliary display area can be increased. Therefore, optical devices such as a camera, a light sensor, a proximity sensor, an optical transmitter, an optical receiver and the like can be arranged below the auxiliary display area, and the optical devices can work normally, so that the working performance of the optical devices is ensured to the maximum extent.

Fig. 2 is a schematic diagram illustrating a terminal screen according to another exemplary embodiment. As shown in fig. 2, the terminal screen may include: a substrate 10 and a display layer 20 disposed on the substrate 10.

The display layer 20 includes a main display area 21 and an auxiliary display area 22.

At least one of the plurality of pixel attributes of the main display area 21 and the sub display area 22 is different, and at least one of the pixel attributes is the same.

For the description of the display layer 20, the main display area 21 and the auxiliary display area 22, reference may be made to the above embodiments, which are not described in detail in this embodiment.

Unlike the embodiment shown in fig. 1, in the present embodiment, the pixel control circuit in which at least one sub-pixel exists in the auxiliary display area 22 is located in the auxiliary display area 22.

In the embodiment of the present disclosure, the size of the pixel control circuit of the auxiliary display area 22 is reduced, so that the pixel control circuit of the auxiliary display area 22 can be placed below the pixels of the auxiliary display area 22 without affecting the light transmission performance of the auxiliary display area 22. In addition, the pixel control circuit of the auxiliary display area 22 is made small, so that the number of components included in the pixel control circuit can be reduced, for example, the 7T1C structure is simplified into a 2T1C structure, a 3T1C structure or even a 1T1C structure, or the capacitor can be omitted. Where T denotes a TFT and C denotes a capacitor, for example, the 7T1C structure denotes a structure including 1 TFT and 1 capacitor, and the 2T1C structure denotes a structure including 2 TFTs and 1 capacitor. Alternatively, the size of the components included in the pixel control circuit can be reduced by a process, so that the whole pixel control circuit is more miniaturized. Alternatively, the same pixel control circuit may be shared by a plurality of sub-pixels in the auxiliary display area 22, so as to reduce the number of pixel control circuits.

In one possible implementation, each sub-pixel in the auxiliary display area 22 corresponds to a pixel control circuit that includes 2 TFTs and 1 capacitor. In this implementation, each sub-pixel in the auxiliary display area 22 has its corresponding pixel control circuit, so that each sub-pixel in the auxiliary display area 22 can be independently controlled. The 2T1C structure is an essential circuit for enabling a sub-pixel to normally write information and emit light, where one TFT is a switch for writing a signal, the other TFT (denoted as DTFT) is a switch for controlling the emission of light from the sub-pixel, and 1 capacitor is used to store the written signal and control the on of the DTFT, and this capacitor may also be referred to as a holding capacitor. In the conventional scheme, each sub-pixel of the screen needs to be connected with a pixel control circuit with a 7T1C structure, namely, a structure comprising 7 TFTs and 1 capacitor, wherein pixel compensation, reset and the like are involved to optimize the circuit performance. In the embodiment of the present disclosure, in order to simplify the structure of the pixel control circuit of the sub-pixels in the auxiliary display area 22 and save space, the structure of 7T1C is simplified to be the structure of 2T1C, only the sub-pixels in the auxiliary display area 22 need to be ensured to emit light normally, and some structures with optimized performance are removed. Thus, after the components of the pixel control circuits of the sub-pixels of the sub-display section 22 are reduced, the size of the pixel control circuits is reduced, so that the pixel control circuits can be placed under the sub-pixels of the sub-display section 22 without being placed outside the sub-display section 22. Of course, in some other examples, the pixel control circuit of each sub-pixel in the auxiliary display area 22 may also be in a 3T1C structure or even in a 1T1C structure, or a capacitor may be omitted, and any way of reducing the number of components of the pixel control circuit by appropriately sacrificing the function of the pixel control circuit is included in the scope of the present disclosure.

In another possible implementation, each sub-pixel in the auxiliary display area 22 corresponds to a pixel control circuit, the pixel control circuit includes 7 TFTs and 1 capacitor, and the size of the pixel control circuit is smaller than the preset threshold. In this implementation manner, the size of the pixel control circuit is not reduced by reducing the number of components of the pixel control circuit, but is reduced by reducing the size of the components of the pixel control circuit through a process on the premise of ensuring that the number of components of the pixel control circuit is not reduced. For example, more miniaturized TFTs and capacitors may be used. The fact that the size of the pixel control circuit of the sub-pixel in the auxiliary display area 22 is smaller than the preset threshold means that the size of the pixel control circuit is reduced compared with the size of the pixel control circuit of the 7T1C structure adopted in the conventional scheme. In this way, the pixel control circuit of the auxiliary display area 22 can also be placed below the sub-pixels of the auxiliary display area 22, and does not have to be placed outside the auxiliary display area 22.

In yet another possible implementation, the auxiliary display area 22 includes at least one first pixel group, each first pixel group includes n sub-pixels of the same color, n sub-pixels in each first pixel group share the same pixel control circuit, and n is an integer greater than 1. For example, the n sub-pixels in each first pixel group share the same trace, and then are connected to the same pixel control circuit through the trace. For example, assuming that 4 sub-pixels share the same pixel control circuit, it is possible to reduce 3 pixel control circuits compared to 4 sub-pixels each having a separate pixel control circuit. In this way, since the number of pixel control circuits in the auxiliary display area 22 is reduced, it is also possible to place the pixel control circuits of the auxiliary display area 22 below the sub-pixels of the auxiliary display area 22 without being placed outside the auxiliary display area 22. In addition, in this implementation manner, the pixel control circuit may adopt a 7T1C structure, may also adopt a 2T1C structure or a structure with a reduced number of other components, and may further reduce the size of the components, so that in the case of reducing the number of the pixel control circuits of the auxiliary display area 22, the size of the pixel control circuit of the auxiliary display area 22 is further reduced, which is more favorable for realizing that the pixel control circuit of the auxiliary display area 22 is placed below the sub-pixels of the auxiliary display area 22.

It should be noted that, in this embodiment, the pixel control circuit corresponding to each sub-pixel in the auxiliary display area 22 may be disposed in the auxiliary display area 22, or the pixel control circuits corresponding to a part of the sub-pixels in the auxiliary display area 22 may be disposed in the auxiliary display area 22, and the pixel control circuits corresponding to another part of the sub-pixels are disposed outside the auxiliary display area 22, which all fall within the protection scope of the present disclosure.

In addition, the size of the pixel control circuit of the auxiliary display area is reduced, so that the pixel control circuit of the auxiliary display area can be placed below the pixels of the auxiliary display area, the light transmission performance of the auxiliary display area cannot be influenced, optical devices can be arranged below the auxiliary display area, and the optical devices can work normally.

In another exemplary embodiment provided based on the embodiment of fig. 1 or fig. 2, the different pixel attributes in the main display area 21 and the auxiliary display area 22 include: the pixel size. In the embodiments of the present disclosure, the pixel size refers to the size of the sub-pixel. Since a pixel usually includes a plurality of sub-pixels, the size of the sub-pixels also determines the size of the pixel. In the embodiments of the present disclosure, the pixel size refers to the size of a light emitting region of a sub-pixel, which is a region where light is emitted.

Any sub-pixel may include a light-emitting region and optionally a non-light-emitting region, the light-emitting region and the non-light-emitting region being determined by the pixel structure. Since the pixels are of a stacked structure, for example, including an anode layer, a light emitting material layer, and a cathode layer, the sizes of the layers of one sub-pixel may be the same or different, for example, the sizes of the anode layer, the light emitting material layer, and the cathode layer of one sub-pixel may be the same or different. When the sizes of the layers of one sub-pixel are the same, for example, the sizes are all the target sizes, the size of the light emitting region of the sub-pixel may also be the target size. When the sizes of the layers of one sub-pixel are different, the size of the light emitting area of the sub-pixel may be the smallest size among the sizes of the layers, for example, the size of the anode layer is smaller than the size of the light emitting material layer and the size of the cathode layer, and the size of the light emitting area of the sub-pixel is the size of the anode layer.

In one possible design, as shown in fig. 1 and 2, the pixel size of the auxiliary display area 22 is smaller than the pixel size of the main display area 21. That is, the size of the sub-pixels in the sub-display area 22 is smaller than the size of the sub-pixels in the main display area 21. When the light emitting area of a sub-pixel is rectangular, the size of the sub-pixel is determined by the length and width of the light emitting area of the sub-pixel, for example, the product of the length and width of the light emitting area is the size of the sub-pixel. Therefore, if the size of the sub-pixel a is smaller than the size of the sub-pixel B, it means that the size of the light emitting region of the sub-pixel a is smaller than the size of the light emitting region of the sub-pixel B, i.e. the length of the light emitting region of the sub-pixel a is smaller than the length of the light emitting region of the sub-pixel B, and/or the width of the light emitting region of the sub-pixel a is smaller than the width of the light emitting region of the sub-pixel B. If the size of the sub-pixel a is larger than that of the sub-pixel B, it means that the size of the light-emitting area of the sub-pixel a is larger than that of the light-emitting area of the sub-pixel B, that is, the length of the light-emitting area of the sub-pixel a is larger than that of the light-emitting area of the sub-pixel B, and/or the width of the light-emitting area of the sub-pixel a is larger than that of the light-emitting area of the sub-pixel B. If the size of the sub-pixel a is equal to the size of the sub-pixel B, it means that the size of the light emitting area of the sub-pixel a is equal to the size of the light emitting area of the sub-pixel B, in this case, the length of the sub-pixel a may be equal to the length of the sub-pixel B and the width of the sub-pixel a may be equal to the width of the sub-pixel B, or the length of the sub-pixel a may be not equal to the length of the sub-pixel B and the width of the sub-pixel a may not be equal to the width of the sub-pixel B, but the product of the length of the sub-pixel a and the width of the sub-pixel a is equal to the product of the length of the sub-pixel B and the. When the size of the sub-pixels in the auxiliary display area 22 is smaller than the size of the sub-pixels in the main display area 21, for example, the length of the sub-pixels in the auxiliary display area 22 may be smaller than the length of the sub-pixels in the main display area 21; and/or the width of the sub-pixels in the auxiliary display area 22 is smaller than the width of the sub-pixels in the main display area 21. Wherein, the side length of the sub-pixel in the transverse direction is the length of the sub-pixel, and the side length in the longitudinal direction is the width of the sub-pixel.

It should be noted that the above-mentioned rectangular light emitting regions of the sub-pixels are only exemplary and explanatory, and the shape of the light emitting regions of the sub-pixels may also be circular, elliptical, diamond, star, or other regular or irregular shapes, which is not limited by the embodiments of the present disclosure.

In addition, the pixel size of the auxiliary display area 22 is smaller than the pixel size of the main display area 21, and may be the size of all sub-pixels in the auxiliary display area 22, which is smaller than the pixel size of the main display area 21; it is also possible that the size of a part of the sub-pixels in the auxiliary display area 22 is smaller than the pixel size of the main display area 21.

Since the light transmission performance of the area where the pixel is located is poor, and the light transmission performance between the pixels is relatively good, the light transmission performance of the auxiliary display area 22 can be better than that of the main display area 21 by designing the pixel size of the auxiliary display area 22 to be smaller than that of the main display area 21, so that an optical sensor can be arranged below the auxiliary display area 22.

In addition, in the above embodiments, the description is mainly given by taking the pixel size as the size of the light emitting region of the sub-pixel as an example, and in some other examples, the pixel size may also refer to the size of the non-light-transmitting portion of the sub-pixel, which is the size of the level where the light transmission performance is lower than a certain predetermined index (e.g., the transmittance is lower than a certain predetermined index) in the stacked structure of the sub-pixel, such as the size of the anode layer, or the size of the cathode layer. The size of the non-light-transmitting portion may be equal to the size of the light-emitting region, e.g. the non-light-transmitting portion completely coincides with the projected area of the light-emitting region in a direction perpendicular to the terminal screen; alternatively, the size of the non-light-transmitting portion may be larger than that of the light-emitting region, for example, the non-light-transmitting portion and the projected region of the light-emitting region in the direction perpendicular to the terminal screen do not completely overlap, and the projected region of the light-emitting region is in the projected region of the non-light-transmitting portion.

In another possible design, as shown in FIG. 3, the pixel size of the auxiliary display area 22 is larger than the pixel size of the main display area 21. That is, the size of the sub-pixels in the sub-display area 22 is larger than the size of the sub-pixels in the main display area 21. For the description of the pixel size, see above, the description is omitted here. In addition, the pixel size of the auxiliary display area 22 is larger than the pixel size of the main display area 21, and may be the size of all sub-pixels in the auxiliary display area 22, which is larger than the pixel size of the main display area 21; it is also possible that the size of a part of the sub-pixels in the auxiliary display area 22 is larger than the pixel size of the main display area 21.

In the design of fig. 3, the pixel material of the auxiliary display area 22 is a transparent material, the pixel material is a material used for making the pixel, and the transparent material is a material having a light transmittance higher than a predetermined index (e.g., a transmittance higher than a predetermined index). Since the auxiliary display area 22 is made of a transparent material, the light transmittance of the auxiliary display area 22 is good, so that an optical sensor can be disposed below the auxiliary display area 22.

It should be noted that, when the pixel material of the auxiliary display area 22 is a transparent material, the pixel size of the auxiliary display area 22 may be larger than the pixel size of the main display area 21, may also be equal to the pixel size of the main display area 21, and may also be smaller than the pixel size of the main display area 21, which is not limited in the embodiment of the present disclosure. In addition, all sub-pixels in the auxiliary display area 22 may be made of a transparent material, or some sub-pixels may be made of a transparent material, which is not limited in the embodiment of the present disclosure.

The same pixel attributes in the main display area 21 and the auxiliary display area 22 include at least one of: resolution, center-to-center spacing of adjacent pixels, pixel arrangement, and pixel structure.

Resolution refers to the number of pixels per unit area. For example, the unit of resolution may be PPI (Pixels per inch, Pixels perench). For example, the resolutions of the auxiliary display area 22 and the main display area 21 are both 400PPI, i.e., the resolutions of the auxiliary display area 22 and the main display area 21 are the same. For another example, the resolution of the auxiliary display region 22 is 500PPI and the resolution of the main display region 21 is 400PPI, i.e., the resolution of the auxiliary display region 22 is greater than the resolution of the main display region 21. In fig. 1 and 2, the resolution of the auxiliary display area 22 is schematically illustrated as being equal to the resolution of the main display area 21.

The center-to-center distance of adjacent pixels refers to the distance between the center points of two pixels located adjacent to each other. For example, if the center-to-center distance between adjacent pixels in the main display area 21 is L, the center-to-center distance between adjacent pixels in the auxiliary display area 22 is also L.

The pixel arrangement mode includes Delta arrangement, Pentile arrangement, standard RGB arrangement, and the like. For example, the main display area 21 and the auxiliary display area 22 have the same pixel arrangement mode, and both are Delta arrangement.

The pixel structure refers to a laminated structure of sub-pixels. For example, the same laminated structure of the sub-pixels in the main display area 21 and the sub-display area 22 means that the layers included in the main display area 21 and the sub-display area 22 and the positional relationship between the layers are the same.

In one example provided by the embodiment of the present disclosure, the resolutions of the main display area 21 and the auxiliary display area 22 are the same, and the pixel size of the auxiliary display area 22 is smaller than that of the main display area 21. Optionally, the resolution of the main display area 21 and the resolution of the auxiliary display area 22 may be the same, and the center distance between adjacent pixels, the pixel arrangement mode, and the pixel structure may be the same, so that the display effects of the main display area 21 and the auxiliary display area 22 are as close as possible, and the integrity of the display effect of the whole terminal screen is improved.

In another example provided by the embodiment of the present disclosure, the resolution of the auxiliary display area 22 is greater than that of the main display area 21, the pixel size of the auxiliary display area 22 is smaller than that of the main display area 21, and the center-to-center distance, the pixel arrangement manner, and the pixel structure of the adjacent pixels of the main display area 21 and the auxiliary display area 22 are the same.

In the embodiment of the present disclosure, by reasonably designing the pixel attributes of the main display area 21 and the auxiliary display area 22, a part or all of the area in the auxiliary display area 22 has a better light transmission performance, so that an optical device can be disposed below the area, and on the premise of ensuring the light transmission performance, the difference between the display effects of the main display area 21 and the auxiliary display area 22 is reduced as much as possible.

It should be noted that, when the resolutions of the main display area 21 and the auxiliary display area 22 are the same, although the number of sub-pixels included in a unit area is the same, for example, the number of sub-pixels included in a unit area X is Y, the area corresponding to each sub-pixel is X/Y, but the X/Y is not equal to the pixel size of the sub-pixel, and the pixel size of the sub-pixel refers to the size of the actual light emitting area of the sub-pixel described above.

It should be noted that, in the embodiment of the present disclosure, the resolution of the main display area 21 and the resolution of the auxiliary display area 22 are the same, which means that at least a partial area in the auxiliary display area 22 and at least a partial area in the main display area 21 have the same resolution. It is also within the scope of the present disclosure to subtract a certain number of sub-pixels from the auxiliary display area 22 such that the resolution of the auxiliary display area 22 is less than the resolution of the main display area 21, for example, the resolution of the main display area 21 is 400PPI and the resolution of the auxiliary display area 22 is 395 PPI. It is also within the scope of the present disclosure to add a certain number of sub-pixels to the auxiliary display area 22 such that the resolution of the auxiliary display area 22 is greater than the resolution of the main display area 21, for example, the resolution of the main display area 21 is 400PPI and the resolution of the auxiliary display area 22 is 410 PPI. Alternatively, in some possible designs, the resolution may be graded in the edge region of the auxiliary display region 22 near the main display region 21, for example, from 400PPI to 380PPI, which falls within the protection scope of the present disclosure.

It should be further noted that, for any pixel attribute, the pixel attribute of the main display area 21 and the pixel attribute of the auxiliary display area 22 described in the embodiments of the present disclosure are the same, which means that the pixel attribute of at least a partial area in the auxiliary display area 22 is the same as the pixel attribute of at least a partial area in the main display area 21; the difference in the pixel attributes of the main display area 21 and the auxiliary display area 22 in the embodiments of the present disclosure means that the pixel attributes of at least a partial area in the auxiliary display area 22 are different from the pixel attributes of at least a partial area in the main display area 21. Taking the pixel attribute as the pixel size as an example, the pixel sizes of the main display area 21 and the auxiliary display area 22 described in the embodiments of the present disclosure are the same, which means that the pixel size of at least a partial area in the auxiliary display area 22 is the same as the pixel size of at least a partial area in the main display area 21; the difference in pixel size between the main display area 21 and the auxiliary display area 22 in the embodiment of the present disclosure means that the pixel size of at least a partial area in the auxiliary display area 22 is different from the pixel size of at least a partial area in the main display area 21.

In another exemplary embodiment provided based on the embodiment of fig. 1 or 2, as shown in fig. 4, the display layer 20 further includes a transition display area 25 (the area indicated by the diagonal line filling in fig. 4), and the transition display area 25 is located between the main display area 21 and the auxiliary display area 22. The pixel control circuits of the auxiliary display area 22 are located in the main display area 21 and/or the transitional display area 25. The pixel control circuits of the auxiliary display area 22 may be entirely located in the main display area 21, entirely located in the transition display area 25, or partially located in the main display area 21 and partially located in the transition display area 25.

Optionally, the same pixel attributes in the transitional display area 25 and the auxiliary display area 22 include at least one of: resolution, center-to-center spacing of adjacent pixels, pixel arrangement, pixel structure, and pixel connection.

The transition display area 25 is used for playing a transition connection role for the display effect between the main display area 21 and the auxiliary display area 22, so that the difference of the display effect between the main display area 21 and the auxiliary display area 22 cannot be suddenly changed, and the display effect of the terminal screen is optimized. For the same pixel attribute between the main display area 21 and the auxiliary display area 22, the pixel attribute of the transitional display area 25 can be the same as that of the main display area 21 and the auxiliary display area 22, so that the integrity of the display effect of the whole terminal screen is ensured; for different pixel attributes between the main display area 21 and the auxiliary display area 22, the pixel attribute of the transition display area 25 may be designed according to the main display area 21 and the auxiliary display area 22, for example, between the main display area 21 and the auxiliary display area 22, or gradually changed, so as to perform the transition joint function.

The pixel connection method is a connection method between sub-pixels. In the embodiment of the present disclosure, a plurality of sub-pixels with the same color in the auxiliary display area 22 may be connected by the same trace and then connected to the corresponding pixel control circuit, so that the number of pixel control circuits may be reduced. When the pixel connection modes of the transition display area 25 and the auxiliary display area 22 are the same, the auxiliary display area 22 may include at least one first pixel group, each first pixel group includes n sub-pixels with the same color, and the n sub-pixels in each first pixel group share the same routing line; the transitional display area 25 may include at least one second pixel group, each second pixel group includes n sub-pixels with the same color, and the n sub-pixels in each second pixel group share the same trace; n is an integer greater than 1.

For example, the auxiliary display area 22 may include at least one first pixel group, each first pixel group includes 4 sub-pixels of the same color, such as 4 red sub-pixels, 4 green sub-pixels, or 4 blue sub-pixels, and the 4 sub-pixels included in each first pixel group share the same trace; likewise, the transitional display area 25 may include at least one second pixel group, each second pixel group includes 4 sub-pixels of the same color, such as 4 red sub-pixels, 4 green sub-pixels, or 4 blue sub-pixels, and the 4 sub-pixels included in each second pixel group share the same trace.
