The present invention relates to a display structure, and more particularly to a display structure and a display panel including an under-screen lens.

Certain types of electronic devices such as notebook computers or smart phones increase the screen-to-body ratio by placing the camera below the screen. However, this often results in a darker screen area above the camera or an increase in display noise in this area. Therefore, how to maintain or even improve the display quality of the screen above the lens as much as possible while setting the under-screen lens is one of the subjects that those skilled in the art are devoted to researching.

The invention provides a display structure and a display panel including an under-screen lens, which can take into account the display quality of the screen above the lens while setting the under-screen lens.

FIG. 1 is a schematic diagram of a display structure according to an embodiment of the present invention. FIG. 2 is a schematic diagram of a display panel according to an embodiment of the invention. Please refer to FIG. 1, the display structure 10 includes a display panel 11, a lens 12 and a panel driver 13. The display panel 11 may include a liquid crystal display (LCD), a thin film transistor liquid crystal (Thin Film Transistor LCD, TFT LCD) display, a field sequential liquid crystal display (Field Sequential LCD, FS LCD), a light emitting diode (light Emitting diode (LED) displays, active-matrix organic light-emitting diode (AMOLED) displays, or electrowetting displays, and other types of transparent display panels (also known as transmissive display panels) ).

The lens 12 is arranged under the display panel 11. The lens 12 is an optical lens. For example, the lens 12 may include one or more image capturing modules. Each image capturing module may include common image capturing elements such as lenses and photosensitive elements. The panel driver 13 is coupled to the display panel 11 and can be used to drive the display panel 11 to display images. For example, the panel driver 13 may include at least one driving circuit (not shown) to provide current (or voltage) to the display panel 11. In addition, the lens 12 and the panel driver 13 can be disposed on a substrate (not shown) in the display structure 10.

The display panel 11 includes display areas 101 and 102. The display area 101 is also referred to as the first display area. The display area 102 is also referred to as a second display area. It should be noted that the lens 12 is disposed under the display area 102 and can capture external images through the display area 102. For example, light may pass through the display area 102 from above the display area 102 and enter the lens 12 below the display area 102 for imaging. In addition, the lower part of the display area 101 does not contain any lens.

It should be noted that the upper and lower portions of the display area 102 are divided based on the normal vector direction of the display panel 11 as a reference. Therefore, assuming that the normal vector of the display panel 11 above the display area 102 is marked as a positive direction, the normal vector of the display panel 11 below the display area 102 can be marked as a negative direction.

2, the display area 101 includes a plurality of pixel arrays PA(1), and the display area 102 includes a plurality of pixel arrays PA(2). The pixel array PA(1) is also referred to as the first pixel array. The pixel array PA(2) is also referred to as the second pixel array. Each pixel array in the pixel arrays PA(1) and PA(2) is formed by the arrangement and combination of a plurality of pixel units. The pixel units in each of the pixel arrays PA(1) and PA(2) include at least two different color pixel units. For example, the red pixel unit (R) can emit red light, the green pixel unit (G) can emit green light, and the blue pixel unit (B) can emit blue light. The pixel units of different colors may include pixel units of at least two colors among a red pixel unit (R), a green pixel unit (G), and a blue pixel unit (B).

It should be noted that there is no white pixel unit (W) in the pixel array PA(1) (that is, no white pixel unit (W)). The white pixel unit (W) can emit white light. At least one white pixel unit (W) exists (that is, includes) in the pixel array PA(2). For example, the pixel array PA(1) may include a red pixel unit (R), a green pixel unit (G), and a blue pixel unit (B), and the pixel array PA(2) may include a red pixel unit (R) and a green pixel unit (G), blue pixel unit (B) and white pixel unit (W). Therefore, the color saturation of the pixel array PA(1) can be higher than the color saturation of the pixel array PA(2), and the light transmittance of the pixel array PA(2) can be higher than the light transmittance of the pixel array PA(1) Spend.

FIG. 3 is a schematic diagram of a first pixel array and a second pixel array according to an embodiment of the invention. 3, in an embodiment, the pixel array PA (1) may include a red pixel unit (R), a green pixel unit (G) and a blue pixel unit (B), and the pixel array PA (2) includes red pixels Cell (R), green pixel cell (G), blue pixel cell (B), and white pixel cell (W). It should be noted that, compared to the pixel array PA(1), the pixel array PA(2) includes more light-transmitting areas (represented by diagonal lines).

In an embodiment of FIG. 3, the size of at least one of the red pixel unit (R), the green pixel unit (G), and the blue pixel unit (B) in the pixel array PA(1) is a certain size (also Called the first size). The size of at least one of the red pixel unit (R), the green pixel unit (G), and the blue pixel unit (B) in the pixel array PA(2) is another size (also referred to as a second size). The second size may be smaller than the first size. For example, the second size may be half of the first size. In addition, the size of the white pixel unit (W) in the pixel array PA(2) may also be the first size.

In an embodiment of FIG. 3, the red pixel unit (R), the green pixel unit (G), and the blue pixel unit (B) in the pixel array PA(1) and the white pixel unit (B) in the pixel array PA(2) The length of W) is all D1 (that is, the first size). The lengths of the red pixel unit (R), the green pixel unit (G) and the blue pixel unit (B) in the pixel array PA(2) are all D2 (that is, the second size). The length D2 can be at or close to half of the length D1.

In an embodiment of FIG. 3, compared to the red pixel unit (R), the green pixel unit (G) and the blue pixel unit (B) in the pixel array PA(1), the red pixel unit (G) in the pixel array PA(2) The additional light-transmitting area (ie, the oblique line area) generated by the size reduction of the pixel unit (R), the green pixel unit (G), and the blue pixel unit (B) can be used to increase the light transmittance of the pixel array PA(2). For example, this additional light-transmitting area can increase the amount of light entering the lens 12 in FIG. 1. In addition, the white pixel unit (W) in the pixel array PA(2) can be used to increase the overall brightness of the pixel array PA(2) to make up for the reduced screen brightness due to the size reduction of some of the pixel units.

Returning to FIG. 2, in an embodiment, there is no white pixel unit (W) in the pixel array PA(1) (that is, no white pixel unit (W), but a green pixel unit (G)). Compared with the pixel array PA(1), the pixel array PA(2) contains (ie includes) at least one white pixel unit (W), but does not exist (ie does not include) any green pixel unit (G). For example, the pixel array PA(1) may include a red pixel unit (R), a green pixel unit (G), and a blue pixel unit (B), and the pixel array PA(2) may include a red pixel unit (R) and a blue pixel unit (B) and white pixel unit (W). Therefore, the color saturation of the pixel array PA(1) can be higher than the color saturation of the pixel array PA(2), and the light transmittance of the pixel array PA(2) can be higher than the light transmittance of the pixel array PA(1) .

4 is a schematic diagram of a first pixel array and a second pixel array according to an embodiment of the invention. 4, in an embodiment, the pixel array PA(1) may include a red pixel unit (R), a green pixel unit (G), and a blue pixel unit (B), and the pixel array PA(2) may include red pixels Cell (R), blue pixel cell (B) and white pixel cell (W). It should be noted that, compared to the pixel array PA(1), the pixel array PA(2) includes more light-transmitting areas (represented by diagonal lines). From another point of view, in the embodiment of FIG. 4, white pixel units (W) are used in the pixel array PA (2) to replace the green pixel units (G) that have less impact on human vision. The array PA(2) provides more light transmittance.

In an embodiment of FIG. 4, the size of at least one of the red pixel unit (R), the green pixel unit (G), and the blue pixel unit (B) in the pixel array PA(1) is a certain size (ie The first size). The size of at least one of the red pixel unit (R) and the blue pixel unit (B) in the pixel array PA(2) is the other size (ie, the second size). The second size may be smaller than the first size. For example, the second size may be half of the first size. In addition, the size of the white pixel unit (W) in the pixel array PA(2) may also be the first size.

In an embodiment of FIG. 4, the red pixel unit (R), the green pixel unit (G), and the blue pixel unit (B) in the pixel array PA(1) and the white pixel unit (B) in the pixel array PA(2) The length of W) is all D1 (that is, the first size). The lengths of the red pixel unit (R) and the blue pixel unit (B) in the pixel array PA(2) are both D2 (that is, the second size). The length D2 can be at or close to half of the length D1.

In an embodiment of FIG. 4, compared to the red pixel unit (R), the green pixel unit (G) and the blue pixel unit (B) in the pixel array PA(1), the red pixel unit (G) in the pixel array PA(2) The additional light-transmitting area (ie, the oblique line area) generated by the size reduction of the pixel unit (R) and the blue pixel unit (B) respectively can be used to increase the light transmittance of the pixel array PA(2). For example, this additional light-transmitting area can increase the amount of light entering the lens 12 in FIG. 1. In addition, the white pixel unit (W) in the pixel array PA(2) can replace the green pixel unit (G) which has less impact on human vision, so as to increase the overall brightness of the pixel array PA(2), thereby making up for the above-mentioned part. The size of the pixel unit is reduced to reduce the brightness of the screen.

It should be noted that in the foregoing embodiments, the dimensions mentioned are all approximate dimensions. For example, if the size of a certain pixel unit is the first size, it means that the size of the pixel unit is substantially equal to the first size. In other words, the size of the pixel unit and the first size only need to be approximately equal, and there may be a reasonable error between the two. In addition, the size of each pixel unit in the foregoing embodiment can be adjusted according to practical requirements, for example, the length D(2) can be enlarged to be greater than half of the length D(1) or shortened to less than half of the length D(1), etc. , The present invention is not limited.

In addition, in the foregoing embodiment, the size ( For example, the length) can also be the same or different, and the present invention is not limited. Alternatively, the pixel units of the same type or color in the first pixel array and the second pixel array may also have the same or different sizes (for example, lengths), which is not limited by the present invention.

Returning to FIGS. 1 and 2, in an embodiment, the panel driver 13 may use a certain current (also referred to as the first current) to drive the pixel array PA(1) of the display area 101 and use another current (also referred to as The second current) drives the pixel array PA(2) of the display area 102. The current value of the second current may be higher than the current value of the first current. By adjusting the respective current values of the first current and the second current, the panel driver 13 can more accurately maintain the brightness of the display areas 101 and 102 at the same or close to the same.

In summary, when the display panel (and the under-screen lens) is operating, the white pixel unit (W) in the second display area can be used to increase the display brightness of the second display area to the same or similar to the display in the first display area Brightness, so as to improve the previous problems of insufficient brightness, poor light penetration and/or excessive noise in the display area where the lens under the screen is located. In addition, the display brightness of the second display area can be further improved by increasing the current value of the driving current of the second display area. On the other hand, since there is no white pixel unit (W) in the first display area, the first display area can still maintain a preset higher level of image display quality (for example, higher color saturation). In this way, the embodiment of the present invention can set the under-screen lens while taking into account the quality of the screen above the lens and even the overall screen display.
