By such arrangement, normal image display of the light-transmitting display area 12 can be ensured to increase the display range of the screen, so that the use experience of the user can be improved.
In the embodiment of the present application, the self-luminous device 30 is an LED lamp bead.
As shown in fig. 4, the area outside the transparent display area 12 is a normal display area 11, when the liquid crystal display panel is in a display state, the normal display area 11 displays a normal picture, the transparent display area 12 realizes color display of the transparent display area 12 by time color mixing, and a specific color mixing method is as follows: at the first frame, source line (data line) of the normal display area 11 transmits normal display data, that is, S1 to S3 and S7 to S9 normally transmit; the source line of the transparent display area 12 transmits only R (red) element signals, i.e., S4 is normally transmitted, and S5 and S6 are closed; the plurality of self-luminous devices 30 surrounding the outer ring of the camera only turn on all red LED lamp beads, and at the moment, the light-transmitting display area 12 transmits red light; in the second frame, the source line of the normal display area 11 transmits normal display data, namely S1-S3 and S7-S9 are normally transmitted; the source line of the transparent display area 12 transmits only the G (green) element signal, i.e., S5 is normally transmitted, and S4 and S6 are turned off; the plurality of self-luminous devices 30 surrounding the outer ring of the camera only turn on all green LED beads, and at this time, the light-transmitting display area 12 transmits green light; in the third frame, the source line of the normal display area 11 transmits normal display data, that is, S4 transmits normally, and S5 and S6 are closed; the source line of the transparent display area 12 transmits only B (blue) element signals, i.e. S6 is normally transmitted, and S4 and S5 are closed; the plurality of self-luminous devices 30 surrounding the outer ring of the camera only turn on all blue LED lamp beads, and at the moment, the light-transmitting display area 12 transmits blue light; with this timing, by time-mixing, one screen display is completed every three frames, so that the light-transmitting display area 12 can be made to normally display an image.

Specifically, the color of each self-luminous device 30 is one of red, green, and blue. In this application, the arrangement sequence of the plurality of self-luminous devices 30 is arranged clockwise along the circumference of the camera according to the luminous colors of the red, green and blue groups, so that the uniformity of the luminous component can be ensured, and the display effect of the screen can be improved.

It is understood that the backlight module 20 generally includes a side-in type backlight module 20 and a direct type backlight module 20. For the side-in type backlight module 20, a backlight (not shown) is generally disposed at one side of the backlight module 20, and light emitted from the backlight is transmitted to the entire backlight module 20 through the light guiding effect of the light guiding plate. The light goes upward after passing through the light guide plate, and part of the light goes downward and then is reflected by the reflecting sheet to reenter the light guide plate, so that the utilization rate of the light is improved. The upward emergent light is dispersed by the diffusion film and condensed by the brightness enhancement film, and finally a light source is provided for the display panel. For the direct type backlight module 20, because there is a gap between the backlight sources, the optical film set is also disposed to perform uniform light, so as to avoid uneven brightness.

Claims (10)
1. A liquid crystal display device, comprising:
a liquid crystal display panel having a regular display region (11) and a light-transmitting display region (12) adjoining the regular display region (11); the liquid crystal display panel comprises a first substrate (13), a second substrate (16), a liquid crystal layer (14) and a color film layer (15) which are positioned between the first substrate (13) and the second substrate (16), wherein the color film layer (15) is arranged avoiding the light-transmitting display area (12);
the backlight module (20) is positioned on one side of the second substrate (16) far away from the first substrate (13) and is arranged corresponding to the conventional display area (11); and
and the backlight is positioned at one side of the second substrate far away from the first substrate (13) and corresponds to the light-transmitting display area (12), and the backlight is a multicolor light source.
2. The liquid crystal display device according to claim 1, wherein the backlight comprises at least three differently colored self-luminescent devices (30), the three differently colored light forming a color mixed backlight within the light transmissive display area (12).
3. The liquid crystal display apparatus according to claim 2, wherein, of the plurality of self-luminous devices (30), adjacent ones of the self-luminous devices (30) have different colors.
4. A liquid crystal display device according to claim 2, wherein the self-luminous devices (30) of three different colors are alternately distributed along a ring shape.
5. The liquid crystal display apparatus according to claim 2, wherein the color of each of the self-luminous devices (30) is one of red, green, and blue.
6. The liquid crystal display device according to any one of claims 1 to 5, further comprising a light receiving member (40), the light receiving member (40) being disposed corresponding to the light transmitting display area (12) and being located below the second substrate (16), the backlight being disposed along a circumferential direction of the light receiving member (40).
7. The liquid crystal display device according to claim 6, further comprising a driving circuit layer disposed on the second substrate (16), wherein the driving circuit layer is configured to drive liquid crystal in the liquid crystal layer (14) to deflect so as to complete image display of the normal display area (11), and when the photosensitive member (40) is in the photosensitive state, the self-luminous device (30) is in an off state, and the driving circuit layer drives the liquid crystal in the light-transmitting display area (12) to be converted into a light-transmitting state so that the photosensitive member (40) can normally operate.
8. The liquid crystal display apparatus according to claim 6, wherein when the photosensitive member (40) is in a photosensitive state and the external environment is dark, the plurality of self-luminous devices (30) are in an on state to expose the photosensitive member (40).
9. The liquid crystal display device according to claim 6, wherein when the photosensitive member (40) is in an off state, the multicolor light source turns on a light source of a single color frame by frame in accordance with a color classification, and when each frame of image display, liquid crystals of sub-pixels of the same color as the light source in the on state are turned on correspondingly to complete the image display of the light-transmitting display area (12) by multi-frame display and time color mixing.
10. A display terminal, characterized in that the display terminal comprises the liquid crystal display device according to any one of claims 1 to 9.
