Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the invention. Rather, they are merely examples of apparatus and methods consistent with aspects of the invention as detailed in the accompanying claims.
In the related art, the liquid crystal display panel includes an upper polarizer (POL, fully referred to as Polarizer), an upper substrate, a liquid crystal layer, a color film layer, an array substrate, a lower polarizer, and a backlight. The upper substrate and the array substrate are arranged oppositely, and a liquid crystal layer is arranged in the middle. The electric field provided by the array substrate controls the turning angle of the liquid crystal molecules of the liquid crystal layer, so that the effect of controlling the transmittance of the liquid crystal molecules of the liquid crystal layer is achieved, namely, light is conducted through the liquid crystal. The light of the backlight source sequentially passes through the lower polaroid, the transparent array substrate, the color film layer, the liquid crystal layer, the upper substrate and the upper polaroid. The color film layer is printed with color blocks of three colors of RGB (red green blue, also called as three primary colors) for filtering, namely, light transmitted to the color film layer is restored to RGB three colors, and the light is transmitted through liquid crystal to obtain the color to be displayed.
In order to realize a real full screen, a widely adopted mode is to embed the existing camera module below the screen. The imaging module is limited by the light transmittance of the screen when imaging, and the light entering amount of the imaging module is influenced by the screen, so that the imaging effect of the under-screen camera is poor.
In order to solve the above problems, embodiments of the present disclosure provide a liquid crystal display panel, an electronic device, and an imaging method, which reduce the influence of light transmittance of a screen by compounding a camera module with a display structure, and provide an amount of light entering the camera module, thereby improving an imaging effect.
Fig. 1 is a schematic structural view of a liquid crystal display panel according to an exemplary embodiment, and as shown in fig. 1, the liquid crystal display panel includes: the device comprises an array substrate 1, an upper substrate 2, a liquid crystal layer 3 arranged between the array substrate 1 and the upper substrate 2 which are oppositely arranged, a color film layer 4 arranged between the liquid crystal layer 3 and the array substrate 1 and an image pickup module.
It should be noted that the lcd panel further includes an upper polarizer (not shown) above the upper substrate 2, a lower polarizer (not shown) below the array substrate 1, and a backlight (not shown) below the lower polarizer.
The camera module comprises a micro-prism array 5 and a transparent photodiode array 6, wherein the micro-prism array 5 is arranged on one side of the liquid crystal layer 3; the transparent photodiode array 6 is disposed on the upper surface of the array substrate 1, and the transparent photodiode array 6 is electrically connected to the data lines in the array substrate 1.
The transparent photodiode array 6 is used to convert the optical signals collected by the microprism array 5 into electrical signals for generating an image.
It should be noted that, in this embodiment, the micro prism array 5 is used to collect ambient light, which is equivalent to the lens of the conventional front camera; the transparent photodiode array 6 is used for converting optical signals into electric signals, and is equivalent to a photosensitive unit of a traditional front-end camera; and the color film layer 4 plays a role in filtering light during imaging, and reduces external light into RGB three-color light, which is equivalent to a filter of a traditional front camera.
Compared with the related art, when imaging is carried out, the path through which the light of the shot object passes is greatly shortened, and the original lens which needs to penetrate through the whole display panel to reach the front camera is changed into the lens which is based on the structure of the embodiment and directly completes the light information collection on the display panel, so that the utilization rate of the light of the object is greatly improved.
Based on the structure, the color film layer 4 has a double filtering function and is used for filtering light rays from a backlight source during display; for filtering ambient light incident on the front face of the display panel during imaging. The color film layer 4 in the existing liquid crystal display panel is combined with the color film layer 4 required by imaging, and imaging is completed under the condition that the structure of the existing display panel is not changed in a large scale, so that the applicability is wide.
The microprism technology is combined with the liquid crystal display technology, so that on one hand, the forward light emission of the existing liquid crystal display is greatly increased, meanwhile, the optical lens of the imaging technology can be formed, and the utilization rate of the microprism is improved.
Because the transparent photodiode is adopted, the transparent photodiode layer can be arranged above the pixel circuit in the array substrate, so that the on-off of the pixel circuit is not influenced, and the light emission of each pixel can be ensured.
In the present embodiment, for the micro prism array 5, it is understood that composite imaging, although the plurality of micro prisms included in the micro prism array 5 are each a small lens, the whole micro prism array 5 is regarded as a whole here, and the whole may be equivalent to one lens. In this embodiment, a light-transmitting area for collecting ambient light on the display panel is defined as a target area at the time of imaging.
It can be understood that, during imaging, in order to achieve light entering in the target area of the display panel, the target area is formed into a light-transmitting area by adjusting the flip angle of the liquid crystal molecules in the target area of the liquid crystal layer 3; and by controlling the flip angle of the liquid crystal molecules in the region other than the target region of the liquid crystal layer 3, the region other than the target region is formed into a non-light-transmitting region, i.e., the pixels of the region other than the target region are turned off, thereby shielding other display light around the target region.
The control of the size of the target area corresponds to the control of the size of the aperture of the lens, that is, the control of the flip angle of the liquid crystal molecules of the liquid crystal layer 3 can realize the control of the size of the aperture.
As an example, by controlling the inversion of the liquid crystal layer 3, a circular light-transmitting region with a radius of 2 cm is formed, and the incidence of external light can be realized in the light-transmitting region, and when the external light is incident, the light collection can be performed, so that the imaging can be realized. Similarly, by controlling the liquid crystal layer 3 to turn over, a circular light-transmitting area with a radius of 3 cm is formed, and compared with a circular light-transmitting area with a radius of 2 cm, the aperture becomes larger, the light incoming amount is more, and the imaging effect is better. That is, by controlling the inversion of the liquid crystal layer 3, the light entering range at the time of image formation is controlled.
In some embodiments, the liquid crystal display panel further includes a proactive region, and the image capturing module is disposed in the proactive region. That is, the micro prism array 5 is provided on one side of the liquid crystal layer 3 corresponding to the front region of the liquid crystal display panel, and the transparent photodiode array 6 is provided on the upper surface of the array substrate 1 corresponding to the front region of the liquid crystal display panel. So as to realize the image capturing function in the front-shooting area of the liquid crystal display panel. At this time, the target area may be a proactive area.
In some embodiments, the proactive region is the entire liquid crystal display panel. That is, the microprism array 5 and the transparent photodiode array 6 are distributed throughout one layer of the display panel. Based on this structure, the entire liquid crystal layer 3 can be used as a target area by controlling the inversion of the liquid crystal layer 3, a maximum aperture range is formed, the entire imaging of the display screen panel is realized, and a relatively better imaging effect can be obtained.
The outside ambient light is converged through the microprism array 5, the optical signals are filtered through the color film layer 4 and then are converted into electric signals through the transparent photodiodes, the transparent photodiode array 6 is electrically connected with the data lines in the array substrate 1, and the electric signals are transmitted to the image processing chip through the array substrate 1, so that imaging can be completed.
In the liquid crystal display panel of the embodiment of the disclosure, a camera module is integrated in the liquid crystal display panel, the camera module comprises a microprism array and a transparent photodiode array, and a light transmission area equivalent to an aperture can be formed by controlling the liquid crystal molecules of the liquid crystal layer to turn over; the transparent photodiode array is arranged on the array substrate and is used for converting optical signals converged by the microprism array corresponding to the light transmission area into electric signals used for generating images, so that the images can be generated according to the electric signals. Based on the composite structure of the camera module and the display structure, the influence of the light transmittance of the display panel is effectively reduced, the light inlet quantity of the camera module of the camera is greatly improved, and the imaging effect of the camera under the screen is effectively improved; the imaging quality of the camera is not lost while the requirements of the existing true full-face screen can be met. Moreover, the microprism technology is combined with the liquid crystal display technology, so that on one hand, the forward light emission of the existing liquid crystal display is greatly increased, and the display effect is improved; meanwhile, the optical lens can also become an optical lens of an imaging technology, and the utilization rate of the microprism is improved. Furthermore, based on the composite structure of the camera module and the display structure, the thickness of the whole display device formed by the liquid crystal display panel can be reduced, and the light and thin development of the display device is facilitated.
