Description

Technical Field

[0001] The present invention relates to the field of display technology, and in particular to a display adjustment device, a display and a display adjustment method. Background Art

[0002] Ultra-thin displays have always been popular, but due to the limitation of LED light sources, it is impossible to achieve the ultimate.

[0003] At present, the commonly used display technologies include LCD (Liquid Crystal Display), OLED (Organic light-emitting diode), Mini LED (Mini light-emitting diode), and Micro LED (Mirco light-emitting diode).

[0004] The disadvantage of LCD is that it needs LED as the backlight. If it is direct-lit, it cannot be ultra-thin. If it is side-lit, it cannot meet the requirements of energy saving. OLED is independently luminous and does not require an independent backlight, so it can be ultra-thin. However, the disadvantage of OLED is that it has the phenomenon of afterimage and screen burn-in, which is irreversible. In addition, the manufacturing process of OLED is complicated and the cost is high. Therefore, both OLED screen phones and OLED TVs on the market are much more expensive than LCD screens, so they cannot be as popular as LCD. Mini LED and Micro LED technologies are the latest display technologies, and they need to solve the problem of mass transfer.

[0005] Therefore, the prior art needs to be improved. Summary of the invention

[0040] Based on the problems existing in the prior art, this embodiment provides a display adjustment device, specifically, Figure 3 and Figure 4 As shown in , the display adjustment device in this embodiment includes:

[0041] The backlight module comprises a reflector 100, a housing 500, an LED light source 200, a main controller and a light sensor 400. The reflector 100 is arranged at the back of the housing 500, and a plurality of scattering particles 110 ( Figure 7 As shown), the LED light source 200 is disposed at the side of the housing 500, and the light sensor 400 is disposed in the housing 500 and connected to the main controller;

[0042] The liquid crystal display module comprises a light-transmitting LCD display screen 300, the LCD display screen 300 is arranged relative to the reflective sheet 100, and an organic polarized light-emitting film 310 ( Figure 8 The light sensor 400 is used to detect the brightness of light on the backlight module, and the main controller controls the LED light source 200 to turn on or off according to the brightness of light detected by the light sensor 400.

[0043] The working principle of the display adjustment device provided in this embodiment is as follows:

[0044] The light-transmitting LCD display screen 300 in this embodiment is provided with an organic polarized light-emitting film 310, so that the LCD display screen 300 can compensate for the lack of light and increase the transmittance of light, while also obtaining the required polarized light source and reducing the dependence on the LED light source; a plurality of scattering particles 110 are provided on the reflective sheet 100 for diffuse reflection of light and improving the utilization rate of light, and the LED light source 200 is arranged at the side position of the shell 500.

[0045] Combination Fig.10 When the backlight module light brightness is insufficient, the LED light source 200 is turned on to provide LED light combined with ambient light for the LCD display screen 300 to display images; Fig. 9 When the backlight module has sufficient brightness, the LED light source is not turned on. At this time, the ambient light passes through the LCD display screen 300 and is reflected to the LCD display screen 300 by the reflective sheet 100 for image display on the LCD display screen 300.

[0046] The light sensor 400 in this embodiment is a specific quantitative standard for measuring whether the brightness of the backlight module is sufficient or insufficient. For example, the target value of the brightness of the backlight module is set by the main controller, the actual value of the brightness of the backlight module is detected by the light sensor 400, and the target value of the brightness of the backlight module is compared with the actual value of the brightness of the backlight module. If the target value of the brightness of the backlight module is less than the actual value of the brightness of the backlight module, it is judged that the brightness of the LCD display screen 300 is sufficient. At this time, the LED light source 200 is controlled by the main controller to be in a closed state, that is, not turned on; if the target value of the brightness of the backlight module is greater than the actual value of the brightness of the backlight module, it is judged that the brightness of the backlight module is insufficient. At this time, the LED light source 200 is controlled by the main controller to be in an on state.

[0047] In this embodiment, the light sensor 400 is used to detect the brightness of the light on the backlight module, wherein the light on the backlight module includes LED light source light and non-LED light source light. LED light source light refers to light provided by the LED light source; non-LED light source light refers to light of a polarized light source generated after light from an external light source passes through the organic polarized light-emitting film 310 of the LCD display screen 300, such as light reaching the reflective sheet 100 after sunlight passes through the organic polarized light-emitting film 310 of the LCD display screen 300. In this embodiment, if the brightness of the non-LED light source light reaches the target value of the backlight module light brightness, the LED light source 200 is not required to provide light, that is, the LED light source 200 is not turned on; if the brightness of the non-LED light source light does not reach the target value of the backlight module light brightness, the LED light source 200 is required to provide light, that is, the LED light source 200 is turned on by the main controller.

[0048] The display adjustment device provided in this embodiment has at least the following beneficial effects:

[0049] The backlight assembly of the present embodiment is provided with a reflective sheet, and the LED light source is arranged at the side position of the shell. There is no need to set a light guide sheet and a light-enhancing film, which can reduce the thickness of the display. The light sensor is used to detect the brightness of the light on the backlight module. When the brightness of the light on the backlight module is insufficient or uneven, the main controller controls the LED light source to turn on. When the brightness of the light on the backlight module is sufficient and uniform, the LCD display screen is used to transmit light. After the non-LED light source light penetrates the LCD display screen, the light is reflected to the LCD display screen through the reflective sheet for displaying images. Therefore, the present embodiment can achieve ultra-thinness, energy saving and environmental protection, and novel design, low cost, suitable for mass production and wide application.

[0050] In one embodiment, if Figure 3 As shown, the light sensor 400 is located on the LCD display screen 300 or the reflective sheet 100 , and the light sensor 400 is arranged in plurality and evenly distributed.

[0051] In this embodiment, the light sensor 400 is used to detect the brightness of the light on the backlight module, and the brightness of the light on the backlight module is the key to controlling whether the LED light source is turned on or not. For example, when the LCD display screen 300 has sufficient sunlight 600, the LED light source 200 does not need to be turned on; when the LCD display screen 300 does not have sufficient sunlight 600, the LED light source 200 needs to be turned on. By combining sunlight 600 and the LED light source 200, light is provided for the LCD display screen 300 to display images. If the brightness of the light on the backlight module is not fully detected, the image display effect of the LCD display screen 300 will be affected. Therefore, the light sensor 400 is set to be multiple and evenly distributed on the LCD display screen 300 or the reflective sheet 100. The light sensor 400 detects the brightness of light at each location on the backlight module, which can provide a guarantee for a good image display effect.

[0052] Optional, such as Figure 5 As shown, the light sensor 400 is located on the reflective sheet 100. The light sensor 400 is electrically connected to the main controller. In order to facilitate the wiring layout of the light sensor 400, the light sensor 400 in this embodiment is disposed on the reflective sheet 100.

[0053] Optional, such as Figure 4 As shown, the light sensor 400 is located on the LCD display screen 300, such as the light sensor 400 is located on the inner wall of the LCD display screen 300. The light sensor 400 is electrically connected to the main controller. In order to quickly detect the brightness of light, the light sensor 400 in this embodiment is set on the LCD display screen 300.

[0054] In one embodiment, if Figure 8 As shown, the LCD display screen 300 includes an upper glass layer 321, a first micro-color film layer 341, a first transparent electrode layer 351, a first orientation film layer 361, a liquid crystal layer 370, a second orientation film layer 362, a second transparent electrode layer 352, a second micro-color film layer 342 and a lower glass layer 322 which are stacked in sequence, wherein a plurality of black film blocks 330 with equal spacing are arranged in the first micro-color film layer 341 and the second micro-color film layer 342. The organic polarized light-emitting film 310 is arranged on the surface of the upper glass layer 321 and the lower glass layer 322, respectively.

[0055] In this embodiment, the upper glass layer 321, the first micro-color film layer 341, the first transparent electrode layer 351, and the first orientation film layer 361 are symmetrically arranged with the lower glass layer 322, the second micro-color film layer 342, the second transparent electrode layer 352, and the second orientation film layer 362, that is, the upper glass layer 321, the first micro-color film layer 341, the first transparent electrode layer 351, and the first orientation film layer 361 are symmetrically arranged with the lower glass layer 322, the second micro-color film layer 342, the second transparent electrode layer 352, and the second orientation film layer 362 on the upper and lower sides of the liquid crystal layer 370. Optionally, the first transparent electrode layer 351 and the second transparent electrode layer 352 are both transparent electrode layers of the TFT pixel matrix. In this embodiment, by arranging organic polarized light-emitting films on the surfaces of the upper glass layer 321 and the lower glass layer 322 and symmetrically arranging them, it is possible to compensate for the lack of light, increase the transmittance of light, and also obtain the required polarized light source, reduce the dependence on LED light sources, and save energy and protect the environment.

[0056] In one embodiment, the LED light source 200 includes a first LED light source and a second LED light source, and the first LED light source and the second LED light source are respectively arranged on the left and right sides of the housing 500, or the first LED light source and the second LED light source are respectively arranged on the upper and lower sides of the housing 500. That is, in this embodiment, the LED light source 200 is arranged at the side of the housing, and there is no need to arrange a light guide sheet and a light enhancement film, which can greatly reduce the thickness of the display and facilitate the development of ultra-thin displays.

[0057] A display includes the display adjustment device as described in the above embodiment, thereby, the display can have all the structural features and beneficial effects of the above display adjustment device, which will not be repeated here.

[0058] A display adjustment method for a display, used to implement the display as described above, such as Figure 1-2 As shown, the following steps are included:

[0059] Setting the backlight module light brightness target value through the main controller;

[0060] Detect the actual brightness value of the backlight module through the light sensor;

[0061] The main controller obtains the actual brightness value of the backlight module light, and determines whether the actual brightness value of the backlight module light is less than the target brightness value of the backlight module light;

[0062] Combination Fig.10 , if the actual value of the backlight module light brightness is less than the target value of the backlight module light brightness, control the LED light source to turn on;

[0063] Combination Fig. 9If the actual brightness value of the backlight module light is greater than or equal to the target brightness value of the backlight module light, the LED light source is controlled not to be turned on. At this time, the light from the non-LED light source passes through the LCD display screen, and is then reflected onto the LCD display screen by the reflective sheet for image display on the LCD display screen.

[0064] In the present embodiment, whether the LED light source 200 is turned on or off is determined according to the brightness of the backlight module light. For example, if the external light source is daylight 600 or non-LED light source light 600, if the daylight 600 makes the actual brightness value of the backlight module light greater than or equal to the target brightness value of the backlight module light, the main controller controls the LED light source 200 not to be turned on. At this time, the daylight 600 light passes through the LCD display screen 300, and is then reflected onto the LCD display screen 300 by the reflective sheet 100 for image display on the LCD display screen 300. If the brightness of the daylight 600 cannot make the actual brightness value of the backlight module light greater than or equal to the target brightness value of the backlight module light, that is, the actual brightness value of the backlight module light is less than the target brightness value of the backlight module light, the main controller controls the LED light source 200 to be turned on. At this time, light is provided by both the LED light source 200 and the daylight 600 for image display on the LCD display screen 300.
