[0027] As described in the background technology, the structure of the VA segment code screen for color display is relatively complex, and the preparation process is cumbersome. It needs to be precisely attached during assembly, which has high technical requirements, resulting in low processing efficiency and increased cost expenditure. With the development of LOCAL DIMMING technology, the partitioned lighting area can be made smaller and smaller, thereby enabling application in more fields.

[0028] In order to solve this technical problem, the utility model provides an imitation segment code screen structure, which is applied to the field of display modules.

[0029] Specifically, please refer to Figure 1-6 The imitation segment code screen structure specifically includes a backlight source 1, a backlight glue frame 2 and a panel 3. One side of the backlight glue frame 2 is bonded to the panel 3, and the backlight source 1 is arranged on the other side of the backlight glue frame 2. A pattern display area is provided on the panel 3. The backlight glue frame 2 is used to make a corresponding light source irradiation area 203 according to the pattern display area, and the light from different light source irradiation areas 203 does not interfere with each other. The backlight source 1 irradiates the panel 3 after being partitioned by the backlight glue frame 2 to light up the pattern display area.

[0030] The imitation segment code screen structure provided by the utility model divides the light irradiated by the backlight source 1 into a plurality of light source irradiation areas 203 through the backlight glue frame 2. After the light is irradiated onto the panel 3, the pattern display area on the panel 3 is illuminated, and the unlit area of ​​the panel 3 is a black area. By independently controlling the backlight source 1 of each light source irradiation area 203, the dark part can be made deeper while keeping the pattern display area bright, thereby improving the contrast, providing better picture quality performance, and better presenting light and dark details. The brightness of each area can be adjusted according to the needs of the display content, which is more energy-efficient than the global backlight, has a simple overall structure, is easy to assemble, has high efficiency, and has low cost. It can achieve the effect of a segment code screen and is better than the segment code screen effect, thereby improving the competitiveness of the product.

[0031] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0032] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0033] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0034] Please refer to Figure 1-6 , provides an imitation segment code screen structure, which includes a backlight source 1, a backlight glue frame 2 and a panel 3, the backlight source 1 is arranged on the bottom surface of the backlight glue frame 2, the upper surface of the backlight glue frame 2 is in contact with the panel 3, and a pattern display area is provided on a side of the panel 3 close to the backlight glue frame 2, the backlight glue frame 2 is partitioned, specifically divided into a plurality of light source irradiation areas 203, the light source irradiation areas 203 are arranged corresponding to the pattern display areas, after the light source on the backlight source 1 irradiates, the light from different light source irradiation areas 203 does not interfere, and after the light irradiates the panel 3, the pattern display area is lit up, thereby achieving the purpose of lighting up the icon.

[0035] Specifically, a layer of black ink 301 is screen-printed on a surface of the panel 3 close to the backlight glue frame 2, and the black ink 301 avoids the pattern display area. The pattern display area is provided with a number of scattered hidden patterns 302, which are also screen-printed on the panel 3 using the screen printing technology. All hidden patterns 302 form a simulated segment code screen pattern. Each hidden pattern 302 can also be divided into multiple code segments, and each code segment corresponds to a light source irradiation area 203. For example, the hidden pattern 302 of the number is divided into seven horizontal and vertical code segments to form an "8" shape. The backlight source 1 is controlled to light up different code segments, thereby lighting up any number from 0 to 9. For other hidden patterns 302, such as lines and independently displayed logo patterns, the light source irradiation area 203 can be directly controlled to light up the hidden pattern 302.

[0036] A liquid crystal display with a local dimming function is used to divide the backlight source 1 into multiple independent areas. The brightness of each area can be controlled individually to form an imitation segment code screen structure, so that the liquid crystal display can achieve the display effect of a segment code screen. With local dimming, when displaying a dark scene, the backlight of the corresponding area will be dimmed or turned off, while the backlight of the bright scene area will maintain or increase the brightness, which can significantly improve the depth of black and the overall contrast, making the image look more vivid and realistic, and facilitating pattern recognition.

[0037] The imitation segment code screen structure provided in Example 1 is further optimized, specifically, as follows Figure 2-4As shown, a positioning groove 201 is provided on the backlight adhesive frame 2, and the backlight source 1 is arranged in the positioning groove 201 and fixed to the backlight adhesive frame 2. The backlight source 1 includes a PCB board 101 and an LED lamp 102, the LED lamp 102 is electrically mounted on the PCB board 101, and the LED lamp 102 is arranged corresponding to the pattern display area, the PCB board 101 is placed in the positioning groove 201, and the PCB board 101 is bonded and fixed to the backlight adhesive frame 2 by adhesive, and a plurality of LED lamps 102 are provided, and according to display requirements, the color of the LED lamp 102 is one or more, and when the color of the LED lamp 102 is one, a bright color is used, such as dark blue. When applied to the dashboard of a car or electric vehicle, the LED lamp 102 uses multiple colors, and red, blue and yellow can be selected. The red LED lamp 102 is an over-standard warning, the yellow LED lamp 102 is a fault, and the blue LED lamp 102 is a normal display, thereby achieving different display effects, and the driving operation status can be intuitively seen.

[0038] For some hidden patterns 302 that do not need to display multiple colors, an LED light 102 of one color can be corresponding to the pattern display area. The LED light 102 corresponding to each hidden pattern 302 can be the same color or different colors. For some hidden patterns 302 that need to display different states, LED lights 102 of multiple colors are set in the pattern display area. Different LED lights 102 illuminate light of different colors to display different effects of the hidden pattern 302, so that the driving status can be intuitively observed.

[0039] The imitation segment code screen structure provided in Example 2 is further optimized. Specifically, Figure 2-4 As shown, a plurality of baffles 202 are arranged on the backlight glue frame 2, and the baffles 202 divide the backlight glue frame 2 into a plurality of light source irradiation areas 203, and the baffles 202 are fitted with the panel 3 to achieve a sealing effect, and the baffles 202 are used to block the light to avoid mutual interference of light from different light source irradiation areas 203, and each light source irradiation area 203 corresponds to a hidden pattern 302, and the side surfaces of the baffles 202 are all opaque surfaces, which can be black surfaces or a layer of reflective paint can be applied on the side walls of the baffles 202 to form a reflective layer, and the baffles 202 can be set separately from the backlight glue frame 2, or can be designed as an integrated structure, and in terms of material, in order to achieve the shading effect, the baffles 202 and the backlight glue frame 2 are both made of opaque materials.

[0040] The working principle of the imitation segment code screen structure provided by the utility model is as follows: a layer of black ink 301 is silk-screened on one surface of the panel 3, and an avoidance zone is set on the black ink 301, the avoidance zone forms a pattern display zone similar to the simulation segment code screen pattern, a hidden pattern 302 is silk-screened in the pattern display zone, and an icon pattern is formed after being irradiated with light. The number and position of the retaining wall 202 are set according to the position and size of the hidden pattern 302, and the number of partitions of the backlight glue frame 2 is designed to form a plurality of light source irradiation zones 203, and the light source irradiation zones 203 are set corresponding to the hidden pattern 302. After the light is irradiated onto the panel 3, the pattern display area on the panel 3 is lit, and the unlit area of ​​the panel 3 is a black area.
