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. 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. 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, as shown in fig. 1, the auxiliary display area 22 includes a first pixel 221 and a second pixel 222, the size of the first pixel 221 is smaller than the size of the pixel 211 in the main display area 21, and the size of the second pixel 222 is greater than or equal to the size of the pixel 211 in the main display area 21. For any one pixel, it includes a light-emitting region and a non-light-emitting region. In the embodiments of the present disclosure, the size of a certain pixel refers to the size of a light emitting region of the pixel. The light emitting area of the pixel may be rectangular, or may be in other shapes, such as a circle, a diamond, or other regular or irregular shapes, which is not limited by the embodiments of the present disclosure. The shapes of the light emitting regions of the respective pixels in the auxiliary display region 22 may be the same or different; the shapes of the light emitting regions of the respective pixels in the main display region 21 may be the same or different; the light emitting areas of the pixels in the auxiliary display area 22 and the pixels in the main display area 21 may have the same or different shapes, and the embodiment of the present disclosure does not limit this.

When the light emitting region of a pixel is rectangular, the size of the pixel is determined by the length and width of the light emitting region of the pixel, for example, the product of the length and width of the light emitting region is the size of the pixel. Therefore, if the size of the pixel a is smaller than the size of the pixel B, it means that the size of the light emitting region of the pixel a is smaller than the size of the light emitting region of the pixel B, that is, the length of the light emitting region of the pixel a is smaller than the length of the light emitting region of the pixel B, and/or the width of the light emitting region of the pixel a is smaller than the width of the light emitting region of the pixel B. If the size of the pixel a is larger than the size of the pixel B, it means that the size of the light emitting area of the pixel a is larger than the size of the light emitting area of the pixel B, i.e. the length of the light emitting area of the pixel a is larger than the length of the light emitting area of the pixel B, and/or the width of the light emitting area of the pixel a is larger than the width of the light emitting area of the pixel B. If the size of the pixel a is equal to the size of the pixel B, it means that the size of the light emitting region of the pixel a is equal to the size of the light emitting region of the pixel B, and at this time, the length of the pixel a may be equal to the length of the pixel B and the width of the pixel a may be equal to the width of the pixel B, or the length of the pixel a may be equal to the length of the pixel B and the width of the pixel a may be equal to the width of the pixel B, but the product of the length of the pixel a and the width of the pixel a is equal to the product of the length of the pixel B and the width of the pixel B.

In addition, as already described above, one pixel generally includes several sub-pixels, and optionally, the auxiliary display area 22 includes a first sub-pixel and a second sub-pixel, the size of the first sub-pixel is smaller than that of the sub-pixels in the main display area 21, and the size of the second sub-pixel is greater than or equal to that of the sub-pixels in the main display area 21. Similarly, the size of a sub-pixel refers to the size of the light-emitting region of the sub-pixel. The light emitting area of the sub-pixel may be rectangular, or may be in other shapes, such as a circle, a diamond, or other regular or irregular shapes, which is not limited by the embodiments of the present disclosure. In addition, the determination method of the size of the sub-pixel is the same as or similar to the determination method of the size of the pixel described above, and is not described herein again.

Note that the size of each pixel in the main display area 21 may be the same or different. When the sizes of the pixels in the main display area 21 are the same, for example, all the pixels are x, the size of the first pixel 221 in the auxiliary display area 22 is smaller than x, the size of the second pixel 222 in the auxiliary display area 22 is larger than or equal to x, the number of the first pixels 221 is at least one, and the number of the second pixels 222 is also at least one, that is, the size of a part of the pixels in the auxiliary display area 22 is smaller than x, and the size of another part of the pixels is larger than or equal to x. When the sizes of the respective pixels in the main display area 21 are different, for example, when there are at least two pixels with different sizes, the size of the first pixel 221 described above is smaller than the size of the pixel in the main display area 21, and the size of the second pixel 222 is larger than or equal to the size of the pixel in the main display area 21, where the pixel in the main display area 21 may be any one pixel in the main display area 21. That is, as long as there is at least one pixel in the main display area 21 that satisfies the condition that the size of the first pixel 221 in the auxiliary display area 22 is smaller than the size of the pixel, and the size of the second pixel 222 in the auxiliary display area 22 is greater than or equal to the size of the pixel, it falls within the scope of the present disclosure.

In addition, in the embodiment of the present disclosure, the light transmission performance of the target area in the auxiliary display area 22 is better than that of the main display area 21. The light transmittance of the target area may be better than that of the whole area of the main display area 21, or may be better than that of a partial area of the main display area 21, which is not limited in the embodiment of the present disclosure. The light transmission performance is an index for measuring the light transmission capability of a 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 target area in the auxiliary display area 22 is greater than the transmittance of the main display area 21, and/or the light transmission quality of the target area in the auxiliary display area 22 is better than the light transmission quality of the main display area 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 target area in the auxiliary display area 22, and since the transmittance and/or the light transmission quality of the target area in the auxiliary display area 22 are better, the working performance of the optical device may be ensured to the greatest extent.

Optionally, the target region includes a region where the first pixel 221 is located. Since the size of the first pixel 221 is smaller than the size of the pixel 211 in the main display area 21, the light transmission performance of the area where the first pixel 221 is located is better than that 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, by designing the size of a part of the pixels in the auxiliary display area 22 to be smaller than the size of the pixels in the main display area 21, the light transmission performance of at least a part of the area in the auxiliary display area 22 can be made to be better than the light transmission performance of the main display area 21, and then an optical device can be arranged below the part of the area.

It should be noted that the first pixels 221 may be distributed in a concentrated manner or in a scattered manner in the auxiliary display region 22, which is not limited in the embodiment of the present disclosure. When the first pixels 221 are distributed in the auxiliary display area 22 in a concentrated manner, a continuous and complete area is formed in the auxiliary display area 22, and the light transmittance is good. This continuous complete area can be used as the target area described above, under which the optics are arranged, thereby ensuring the operational performance of the optics. Alternatively, the first pixel 221 may be located in the middle region of the auxiliary display region 22, and the second pixel 222 may be located in the edge region of the auxiliary display region 22 (i.e., the region adjacent to the main display region 21), as shown in fig. 1, so that the display effect of the region where the auxiliary display region 22 and the main display region 21 meet is as similar or close as possible, and a natural transition is achieved.

Alternatively, the resolution of the auxiliary display area 22 is equal to the resolution of the main display area 21, or the resolution of the auxiliary display area 22 is greater than the resolution of the main display area 21.

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, the resolution of the auxiliary display area 22 is schematically illustrated as being equal to the resolution of the main display area 21.

Since the resolution of the auxiliary display area 22 is equal to or even greater than the resolution of the main display area 21, the light transmittance of the auxiliary display area 22 can be improved by reducing the pixel size of the auxiliary display area 22 on the premise of ensuring the display effect of the auxiliary display area 22 as much as possible.

Alternatively, in order to further improve the display effect of the terminal screen and reduce or even eliminate the display difference between the auxiliary display area 22 and the main display area 21 as much as possible, the center-to-center distance between adjacent pixels in the auxiliary display area 22 may be designed to be the same as the center-to-center distance between adjacent pixels in the main display area 21, the pixel arrangement manner of the auxiliary display area 22 may be designed to be the same as the pixel arrangement manner of the main display area 21, the pixel structure of the auxiliary display area 22 may be designed to be the same as the pixel structure of the main display area 21, and so on. 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 the components of the pixel, and the positional relationship between the respective components of the pixel. For example, the pixel stacking structure of the main display area 21 and the sub display area 22 is the same.

Of course, in some other examples, the center-to-center distance between adjacent pixels in the auxiliary display area 22 may also be different from the center-to-center distance between adjacent pixels in the main display area 21, the pixel arrangement manner of the auxiliary display area 22 may also be different from the pixel arrangement manner of the main display area 21, and the pixel structure of the auxiliary display area 22 may also be different from the pixel structure of the main display area 21, which is not limited in this disclosure.

Alternatively, at least one pixel may be scratched out of the secondary display area 22 if necessary to further enhance the light transmission performance of the secondary display area 22. Optionally, the pixels in the auxiliary display area 22 are uniformly distributed in the auxiliary display area 22, so as to ensure that the display effect of each part of the auxiliary display area 22 is as same as or close to each other as possible, and avoid the situation that the display effect of a certain area is obviously inferior to that of other areas. For example, in the auxiliary display area 22, one pixel is subtracted from each rectangular pixel array composed of 2 × 2 pixels, and the position of the subtracted one pixel in the 2 × 2 rectangular pixel array is the same, for example, the one pixel at the upper left side is the same. Of course, in some other examples, the pixels scratched out in the secondary display area 22 may also be distributed non-uniformly or randomly in the secondary display area 22, which is not limited by the embodiment of the present disclosure. In addition, in order to ensure the display effect of the auxiliary display area 22, the ratio of the number of pixels subtracted from the auxiliary display area 22 to the number of original pixels before subtraction in the auxiliary display area 22 is less than or equal to 25%, for example, the number of original pixels before subtraction in the auxiliary display area 22 is 1000, the number of pixels subtracted in the auxiliary display area 22 is at most 250, otherwise, the display effect of the auxiliary display area 22 is affected.

In an exemplary embodiment, if the light transmittance of the auxiliary display area 22 needs to be further improved, the light transmittance of the area between the adjacent pixels in the auxiliary display area 22 may be optimized to improve the light transmittance of the area between the adjacent pixels in the auxiliary display area 22. The light transmission performance optimization process refers to a process for further improving the transmittance and/or the light transmission quality, and for example, the material of the region between the adjacent pixels in the auxiliary display region 22 may be appropriately processed to further improve the light transmission performance of the region.

In addition, the auxiliary display area 22 has a corresponding pixel control circuit for performing 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 functions of switching control, pixel compensation, light emission driving, and the like of a 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.

In one possible implementation, the pixel control circuitry of the secondary display area 22 is located below the pixels of the secondary display area 22. For example, below each sub-pixel of the sub-display region 22, a pixel control circuit corresponding to the sub-pixel is provided. Alternatively, the pixel control circuit of the auxiliary display area 22 may be miniaturized to reduce the occupied area of the pixel control circuit as much as possible, so that the pixel control circuit can be disposed below the sub-pixels without occupying the area between the sub-pixels, thereby ensuring that the auxiliary display area 22 has high light transmittance. For example, the number of TFTs included in the pixel control circuit of the auxiliary display region 22 may be appropriately reduced, only necessary circuits for enabling the sub-pixels to normally write information and emit light are reserved, and some structures for optimizing circuit performance, such as pixel compensation and reset, are omitted, thereby reducing the area occupied by the pixel control circuit. Or, the size of the components included in the pixel control circuit can be reduced through the process, so that the whole pixel control circuit is more miniaturized.

In another possible implementation, the pixel control circuits of the auxiliary display area 22 are 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 yet another possible implementation, as shown in fig. 2, the display layer 20 further includes a transition display area 23 (the area indicated by the diagonal lines in the figure is filled), and the transition display area 23 is located between the main display area 21 and the auxiliary display area 22. The transition display area 23 may have the same resolution as the main display area 21 and the auxiliary display area 22. Or, when the resolutions of the main display area 21 and the auxiliary display area 22 are different, for example, when the resolution of the auxiliary display area 22 is greater than the resolution of the main display area 21, the resolution of the transition display area 23 may be between the resolutions of the main display area 21 and the auxiliary display area 22, so as to implement a smooth transition of the resolutions, and improve the display effect of the whole terminal screen. When the display layer 20 further comprises a transitional display area 23, the pixel control circuitry of the secondary display area 22 may be located in the transitional display area 23 and/or the primary display area 21. The pixel control circuits of the auxiliary display region 22 may be entirely located in the main display region 21, entirely located in the transition display region 23, or partially located in the main display region 21 and partially located in the transition display region 23.

The size and structure of the pixel control circuit in the sub display region 22 may be the same as or different from those of the pixel control circuit in the main display region 21. In one example, the size of the pixel control circuit of the sub display area 22 is smaller than the size of the pixel control circuit of the main display area 21. That is, the pixel control circuit of the sub display area 22 is made small compared to the pixel control circuit of the main display area 21, so that the pixel control circuit of the sub display area 22 can be placed under the pixels of the sub display area 22 without affecting the light transmission performance of the sub 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.

In addition, the terminal screen provided by the embodiment of the present disclosure may be an OLED (Organic Light-emitting diode) screen, and may also be other types of screens, such as an LCD (Liquid crystal display) screen, and the like. Taking the OLED screen as an example, the display layer 20 may include a cathode, an electron transport layer, an organic light emitting layer, a hole transport layer, and an anode, which are sequentially stacked from top to bottom. The substrate 10 is located under the display layer 20 and plays a role of bearing.

It should be noted that, in the embodiment of the present disclosure, the positional relationship between the auxiliary display area 22 and the main display area 21 is not limited.
