Description

Technical Field

[0001] This invention relates to the field of liquid crystal display color gamut display testing technology, specifically to an automated testing device for high-performance fusion liquid crystal displays used in aviation. Background Technology

[0002] In the field of automated testing of airborne LCD displays, most existing testing devices employ fixed-size fixture structures with non-adjustable clamping distances. This limits their applicability to displays of a single specification or a very small range of sizes. However, airborne displays vary in shape, size, and thickness depending on the aircraft model, making it impossible for fixed fixtures to achieve universal clamping. This is particularly problematic during positioning, where misalignment or uneven force can easily occur, affecting subsequent testing accuracy. Furthermore, the display testing components of traditional testing devices are typically fixed in one position, requiring manual adjustment of the display or testing head before testing. This cumbersome operation makes it difficult to ensure the perpendicular alignment of the testing surface with the display screen, resulting in significant deviations in the optical path acquisition angle during color gamut testing and poor data repeatability.

[0003] Industry attempts have explored combining adjustable clamps with independent power modules, but these solutions often separate the clamping and adjustment mechanisms from the power connection mechanism, resulting in a bulky overall structure. During adjustment, it's difficult to synchronize the clamping force with the interface position, especially when the monitor size changes, as the height and horizontal position of the power interface cannot be adjusted accordingly, still requiring manual intervention for alignment. More critically, existing devices' detection components, when performing color gamut testing, cannot automatically avoid the top space of the monitor after positioning, causing positional interference between the detection components and the clamping mechanism. This forces operators to perform positioning, power-on, and testing steps separately, severely restricting the testing cycle time. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an automated testing device for high-performance fusion liquid crystal displays on aircraft, which has advantages such as easy positioning and clamping of liquid crystal displays of different sizes and alignment for power supply, thus solving the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a positioning component, which is provided with a driving component; and a telescopic component that extends and retracts relative to the positioning component, wherein the driving component and the telescopic component cooperate to position the liquid crystal display. The rotating block, the first shaft, and the sixth plate are positioned on top of the drive assembly and rotate relative to the drive assembly.

The angle between the first detection module and its adjacent second detection module, and between two adjacent second detection modules, is adjustable from 0 to 180 degrees, so that the first detection module and the second detection modules can cover any position of the liquid crystal display.

[0006] By adjusting the angle between the first and second detection modules, and between adjacent second detection modules, the detection module group can be made into a long strip shape to detect whether there is a color gamut display deviation in a large-sized LCD display. By adjusting the first and second detection modules, the detection module group can be made into a wave shape to cover a large area in the middle of the display to detect whether there is a color gamut display deviation. When the detection module group is adjusted to an L-shape, it can cover the edge of the LCD display to detect whether there is a color gamut display deviation at the edge of the display. According to different detection needs, the detection module group can be adjusted to cover different positions of the display, making the detection results more accurate and applicable to different detection needs.

[0013] Furthermore, the connection between two adjacent second detection modules and between the first and second detection modules is via a connecting plate and a third shaft. The second shaft is connected to the sixth and seventh plates via bearings.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes an automated testing device for high-performance fusion liquid crystal displays for airborne applications.

[0020] Please see Figures 1-8 The positioning component 100 is provided with a driving component 110; and a telescopic component 120 that extends and retracts relative to the positioning component 100, wherein the driving component 110 and the telescopic component 120 cooperate to position the liquid crystal display. The rotating block 310, the first shaft 320, and the sixth plate 330 are positioned on top of the drive assembly 110 and rotate relative to the drive assembly 110. The detection module group 350 is provided with a first detection module 351 that rotates relative to the sixth plate 330. The first surface of the first detection module 351 is provided with a plurality of second detection modules 353 that are rotatably connected end to end. The angle between the first detection module 351 and its adjacent second detection module 353, and between two adjacent second detection modules 353, is adjustable from 0 to 180 degrees, so that the first detection module 351 and the second detection modules 353 can cover any position of the liquid crystal display. The first surface of the first detection module 351 is the back side away from the sixth plate 330.

[0021] Because of the above-mentioned features of this invention, by adjusting the angle between the first detection module 351 and the second detection module 353, and between two adjacent second detection modules 353, the detection module group 350 can be elongated to detect whether there is a color gamut display deviation in a larger-sized liquid crystal display. By adjusting the first detection module 351 and the second detection module 353, the detection module group 350 can be wavy to cover a large area of ​​the central part of the display to detect whether there is a color gamut display deviation. When the detection module group 350 is adjusted to be L-shaped, it can cover the edge of the liquid crystal display to detect whether there is a color gamut display deviation at the edge of the display. According to different detection requirements, the detection module group 350 can be adjusted to cover different positions of the display, making the detection results more accurate and applicable to different detection needs.

[0022] The following describes in detail the specific implementation methods for achieving the above-mentioned technical features and the effects that can be further produced.

[0023] In one specific implementation, the detection module group 350 includes a first detection module 351. The top and bottom of the first detection module 351 near the rotating block 310 are fixedly connected to a second shaft 352. The back of the first detection module 351 is rotatably connected to a second detection module 353. Three second detection modules 353 are sequentially connected to the back of the second detection module 353. In one specific embodiment, the connection between two adjacent second detection modules 353 and between the first detection module 351 and the second detection module 353 is connected and positioned to the third shaft 355 via a connecting plate 354. The second shaft 352 is connected to the sixth plate 330 and the seventh plate 340 via bearings. The first detection module 351 has a rounded corner on the side near the rotating block 310, and the axis of the rounded corner of the first detection module 351 is on the same straight line as the axis of the second shaft 352.

[0024] By connecting the first detection module 351 and rotating the second detection module 353 relative to the third axis 355, the second detection module 353 and the connecting plate 354 rotate relative to the third axis 355 connected to the first detection module 351. The rotation of the second detection module 353 relative to the connecting plate 354 causes the first detection module 351 to rotate. The included angle between two adjacent second detection modules 353 can be adjusted from zero to 180 degrees. Then, the first detection module 351 and the second detection module 353 can form a straight line to perform color gamut display detection on the liquid crystal display. They can also be bent to cover any position on the liquid crystal display. Users can adjust the shape of the detection module group 350 according to the actual needs of the detection. During the detection, multiple angles can be adjusted to detect the color gamut display of the liquid crystal display, thereby ensuring the accuracy of the detection results.

[0025] The positioning component 100 includes a drive component 110, a telescopic component 120 is threadedly connected to one side of the drive component 110, and an electrical connection component 130 is slidably connected to the inner side of the drive component 110.

[0026] The drive assembly 110 includes a first plate 111, a drive unit 112 is fixedly connected to the other side of the first plate 111, a screw 115 is fixedly connected to the output shaft of the drive unit 112, two second plates 113 are fixedly connected to the bottom of one side of the first plate 111, a chamber 116 is opened on one side of the second plate 113, and a slide rail 114 is fixedly connected to the side of the second plate 113 near the electrical connection assembly 130.

[0027] The telescopic assembly 120 includes a third plate 121, a fourth plate 122 fixedly connected to the other side of the third plate 121, and a fifth plate 123 fixedly connected to the other side of the fourth plate 122.

[0028] During the implementation of the above technical solution, some problems exist. During the testing process, the sizes of the LCD monitors being tested are different, and the location of their power interfaces is also different. Currently, most monitors are connected to the power interface via wires. Therefore, existing equipment cannot supply power to the monitor and cannot determine whether the color gamut display deviation is related to voltage.

[0029] The electrical connection assembly 130 includes a first slider 131, with a horizontally extending groove 132 on both its front and back sides. A block 133 is slidably connected to the top of the first slider 131, and a second slider 134 is fixedly connected to both its front and back sides. A charging interface 135 is fixedly connected to one side of the block 133. The dimensions of the groove 132 and the cross-sectional dimensions of the slide rail 144 are matched, allowing the electrical connection assembly 130 to slide relative to the slide rail 114 through the cooperation of the groove 132 and the slide rail 114. This invention allows for the adjustment of the distance between the telescopic component 120 and the driving component 110 to clamp and position the liquid crystal display by telescopically extending the telescopic component 120 relative to the driving component 110. After the liquid crystal display is positioned, the display detection component 300 is rotated relative to the driving component 110 so that the display detection component 300 is located at the top of the liquid crystal display. The power interface of the display is slidably connected through the electrical connection component 130 to power on the display. The display detection component 300 also detects whether the display color gamut of the display is normal, enabling it to position and connect power to displays of different sizes. Furthermore, it can monitor the stability of the voltage when there is a deviation in the color gamut to prevent voltage from affecting the color gamut.

[0030] The display detection component 300 includes a rotating block 310, a first shaft 320 fixedly connected to the front and back of the rotating block 310, a sixth plate 330 fixedly connected to the top of one side of the rotating block 310, a seventh plate 340 fixedly connected to the bottom of one side of the rotating block 310, and a detection module group 350 rotatably connected to the inner side of the rotating block 310 and the seventh plate 340.

[0031] During the implementation of the above solution, some problems exist, specifically as follows: When the existing equipment is used to locate LCD displays of different sizes, the detection range of its detection components is limited to the edge portion. When detecting larger LCD displays, the smaller edge portion makes it difficult to reflect whether the overall color gamut of the LCD display is displayed normally.

[0032] The second detection module 353 has diagonal notches on its front and back sides. The inner side of the notches in the second detection module 353 is connected to the third shaft 355 through a bearing. The notches in the second detection module 353 are rounded. The axis of the rounded corners of the second detection module 353 is on the same straight line as the axis of the third shaft 355, which makes it easy to adjust the angle between the first detection module 351 and the second detection module 353 and adjust the detection position of the LCD.

[0033] The connecting plate 354 has rounded corners on both the front and back. The axis of the rounded corners of the connecting plate 354 is on the same straight line as the axis of the third shaft 355, which facilitates the rotation of the connecting plate 354 relative to the first detection module 351 and the second detection module 353.

[0034] The bottom of the positioning component 100 is fixedly connected to a support component 200. The support component 200 includes a first frame 210, a first rod 220 fixedly connected to one side of the first frame 210, a second rod 230 telescopically connected to one side of the first rod 220, a second frame 240 fixedly connected to one side of the second rod 230, and a wheel 250 rotatably connected to the bottom of the second frame 240. The first rod 220 telescopically extends relative to the second rod 230. When the telescopic component 120 extends relative to the drive component 110, the second frame 240 moves with the third plate 121, effectively supporting the extension of the positioning component 100, and the wheel 250 facilitates the movement of the second frame 240.

[0035] Working principle: By extending and retracting the telescopic component 120 relative to the driving component 110, the distance between the telescopic component 120 and the driving component 110 can be adjusted to clamp and position the liquid crystal display, enabling the liquid crystal display to be clamped and positioned. After the liquid crystal display is positioned, the display detection component 300 rotates relative to the driving component 110, so that the display detection component 300 is located on top of the liquid crystal display. The power interface of the display is slidably connected through the electrical connection component 130 to power on the display and display. The display detection component 300 detects whether the display color gamut of the display is normal, enabling it to position and connect the power supply to displays of different sizes. By connecting the first detection module 351 and rotating the second detection module 353 relative to the third axis 355, the second detection module 353 and the connecting plate 354 rotate relative to the third axis 355 connected to the first detection module 351. The rotation of the second detection module 353 relative to the connecting plate 354 causes the first detection module 351 to rotate. The included angle between two adjacent second detection modules 353 can be adjusted from zero to 180 degrees. Then, the first detection module 351 and the second detection module 353 can form a straight line to perform color gamut display detection on the liquid crystal display. They can also be bent to cover any position on the liquid crystal display. Users can adjust the shape of the detection module group 350 according to the actual needs of the detection. During the detection, multiple angles can be adjusted to detect the color gamut display of the liquid crystal display, thereby ensuring the accuracy of the detection results.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
