Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a schematic structural diagram of a display panel according to an embodiment of the present invention, and fig. 2 is an enlarged schematic structural diagram of fig. 1 at a point a, as shown in fig. 1 and fig. 2, the display panel according to the embodiment of the present invention includes a first display area 11, a second display area 12, and a third display area 13, which are sequentially and adjacently disposed, where the first display area 11 includes a plurality of first pixel units 111 arranged in an array, and the second display area 12 includes a plurality of second pixel units 121 arranged in an array. The first pixel unit 111 includes a first sub-pixel unit 21 and a first light transmission region 22, and the second pixel unit 121 includes a second sub-pixel unit 23 and a second light transmission region 24, wherein the area of the second light transmission region 24 is smaller than the area of the first light transmission region 22.
Specifically, as shown in fig. 1 and fig. 2, the display panel according to the embodiment of the present invention is suitable for a display device in which a light sensing element is disposed under a screen, and the display panel includes a first display area 11, a second display area 12, and a third display area 13, where the second display area 12 is located between the first display area 11 and the third display area 13, and both the first display area 11 and the second display area 12 can be reused as a region for disposing the light sensing element, where the light sensing element may be a camera, an infrared sensor, and the like, which is not limited in the embodiment of the present invention.
The first display region 11 includes a plurality of first pixel units 111 arranged in an array, and the first pixel units 111 include first sub-pixel units 21 and first light-transmitting regions 22. When the light sensing element works, the first light-transmitting area 22 is in a light-transmitting state, and external light can enter the light sensing element through the first light-transmitting area 22, so that the normal work of the light sensing element is ensured. When the display panel displays normally, the first sub-pixel unit 21 emits light to realize normal display of the first display area 11, so that the screen ratio of the display panel is improved; first light transmission region 22 is in opaque state when display panel normally shows, and at this moment, first light transmission region 22 shows for black, avoids influencing first sub-pixel unit 21's color purity, guarantees the color saturation of first display region 11 to compromise the normal demonstration and the transmissivity of first display region 11, realize full-screen display.
For example, taking a display panel as an example of a liquid crystal display panel, the liquid crystal display panel provides a light source through a backlight module, and generally includes a Color Filter (CF) substrate, a Thin Film Transistor (TFT) array substrate, and a liquid crystal layer between the CF substrate and the TFT array substrate. The working principle is that the liquid crystal molecules in the liquid crystal layer are controlled to rotate by applying driving voltage, and a light source provided by the backlight module penetrates through the TFT array substrate of the liquid crystal display panel, is refracted out of the liquid crystal layer of the liquid crystal display panel, and generates a color picture through the CF substrate. The first light-transmitting area 22 may be an area without a color filter, and when the light sensing element operates, the liquid crystal molecules in the liquid crystal layer of the first light-transmitting area 22 are controlled to rotate by applying a driving voltage, so that the first light-transmitting area 22 is in a light-transmitting state, and external light enters the light sensing element through the first light-transmitting area 22; when the display panel normally displays, the first light transmission region 22 does not apply driving voltage, so that liquid crystal molecules in a liquid crystal layer of the first light transmission region 22 do not rotate, the first light transmission region 22 is in a light-tight state, at the moment, the first light transmission region 22 displays black, the color purity of the first sub-pixel unit 21 can be prevented from being influenced, the color saturation of the first display region 11 is ensured, the normal display and the transmittance of the first display region 11 are considered, and full-screen display is realized.
It should be noted that, when the light sensing element is operated, the first sub-pixel unit 21 may be set to transmit light, so that external light can be incident on the light sensing element through the first sub-pixel unit 21; in other embodiments, for example, when the external light is sufficient, the first sub-pixel unit 21 may be configured to be opaque when the light sensing element is operated, so that the external light is incident on the light sensing element only through the first transparent region 22.
Similarly, the second display region 12 includes a plurality of second pixel units 121 arranged in an array, and the second pixel units 121 include second sub-pixel units 23 and second light-transmitting regions 24. When the light sensing element works, the second light-transmitting area 24 is in a light-transmitting state, and external light can enter the light sensing element through the second light-transmitting area 24, so that the normal work of the light sensing element is ensured. When the display panel displays normally, the second sub-pixel unit 23 emits light to realize normal display of the second display area 12, so that the screen ratio of the display panel is improved; the second light-transmitting area 24 is in a light-tight state when the display panel normally displays, at this time, the second light-transmitting area 24 displays black, the color purity of the second sub-pixel unit 23 is prevented from being affected, the color saturation of the second display area 12 is guaranteed, the normal display and the transmittance of the second display area 12 are considered, and full-screen display is achieved.
The first light transmission area 22 and the second light transmission area 24 are in a light-tight state during displaying to form a dark area, the second display area 12 is arranged between the first display area 11 and the third display area 13 to serve as a transition area, the area of the second light transmission area 24 of the second display area 12 is smaller than that of the first light transmission area 22, the area of the dark area formed by the second light transmission area 24 during displaying can be reduced, human eyes are not sensitive to the reduced dark area, the phenomenon of uneven displaying in the visual effect between the first display area 11 and the third display area 13 is improved, and the display effect of the display panel is improved.
For example, fig. 3 is a schematic structural diagram of a display panel without a second display area, as shown in fig. 3, a winding design is usually adopted between a third display area 13 and a first display area 11, so that a winding area 10 with a large area exists between the third display area 13 and the first display area 11, and since a metal trace of the winding area 10 may reflect external light to cause contrast reduction and seriously affect image quality, the winding area 10 is usually shielded by a Black Matrix (BM) on a color filter substrate, so that the winding area 10 is displayed as Black, thereby ensuring a display effect. When the display panel normally displays, the first light-transmitting area 22 is in a non-light-transmitting state, at this time, the first light-transmitting area 22 also displays black, and at the boundary between the third display area 13 and the first display area 11, a part of the first light-transmitting area 22 and the winding area 10 are connected into a piece to form a large dark area, so that an obvious black wavy stripe appears at the boundary between the third display area 13 and the first display area 11, and the phenomenon of uneven display exists in the visual effect between the first display area 11 and the third display area 13, thereby affecting the display effect of the display panel.
With reference to fig. 2, in the display panel provided in the embodiment of the present invention, the second display area 12 is disposed between the first display area 11 and the third display area 13, and the area of the second light-transmitting area 24 of the second display area 12 is smaller than the area of the first light-transmitting area 22, so that the area of the dark area formed by the second light-transmitting area 24 and the winding area 10 can be reduced, and human eyes are not sensitive to the reduced dark area, thereby implementing transition from the first display area 11 to the third display area 13, and improving the display effect of the display panel.
It should be noted that fig. 1 and fig. 2 are only one example in the embodiment of the present invention, and in other embodiments, a person skilled in the art may set the number, arrangement, structure, size, and the like of the first pixel unit 111 and the second pixel unit 121 according to actual requirements, which is not limited in the embodiment of the present invention.
In addition, the size, number, shape, position and relative positional relationship with the third display area 13 of the first display area 11 and the second display area 12 are not limited in the embodiment of the present invention, for example, the first display area 11 may be one or more, and the first display area 11 may be set to any shape such as a rectangle, a circle, a trapezoid, a water drop, and the like. Also, the first display region 11 and the second display region 12 may be disposed at one side of the third display region 13, and the third display region 13 may be disposed to surround the first display region 11 and the second display region 12. Taking the display panel applied to the mobile phone as an example, the first display area 11 and the second display area 12 may be disposed at the upper left corner or the upper right corner of the display panel, so that the first display area 11 and the second display area 12 may be utilized to display time, weather, information prompt, and the like, and a person skilled in the art may set the first display area 11 and the second display area 12 according to actual requirements.

When the display panel normally displays, the first sub-pixel unit 21 and the second sub-pixel unit 23 emit light, the first transparent area 22 and the second transparent area 24 are in an opaque state, a dark area is formed, the color purity of the first sub-pixel unit 21 and the second sub-pixel unit 23 can be prevented from being affected, and the color saturation of the first display area 11 and the second display area 12 is ensured. The second display area 12 is arranged between the first display area 11 and the third display area 13, the area of the second light transmission area 24 of the second display area 12 is smaller than that of the first light transmission area 22, the dark area formed by the second light transmission area 24 during display can be reduced, human eyes are insensitive to the reduced dark area, transition from the first display area 11 to the third display area 13 is achieved, the phenomenon of display unevenness existing in the visual effect between the first display area 11 and the third display area 13 is improved, and the display effect of the display panel is improved.

Specifically, as shown in fig. 7, the fifth display region 15 includes a plurality of fifth pixel units 151 arranged in an array, and the fifth pixel units 151 include fifth sub-pixel units 25 and third light-transmitting regions 26. When the light sensing element works, the third light-transmitting area 26 is in a light-transmitting state, and external light can be incident to the light sensing element through the third light-transmitting area 26, so that the normal work of the light sensing element is ensured. When the display panel displays normally, the fifth sub-pixel unit 25 emits light to realize normal display of the fifth display area 15, so that the screen ratio of the display panel is improved; the third light-transmitting area 26 is in a light-tight state when the display panel normally displays, at this time, the third light-transmitting area 26 displays black, the color purity of the fifth sub-pixel unit 25 is prevented from being affected, the color saturation of the fifth display area 15 is ensured, and therefore the normal display and transmittance of the fifth display area 15 are taken into consideration, and full-screen display is achieved.

Therefore, by setting the area S1 of the first sub-pixel 211 and the area S2 of the second sub-pixel 231 in the first display area 11 to be larger than the area S3 of the third sub-pixel 60 in the third display area 13, the display brightness of the first display area 11 and the second display area 12 is improved, and the imaging effect of the light sensing elements is improved, and the influence on the display effect of the display panel is reduced.
