Abstract
Description
Technical Field
[0001] The utility model relates to an integrated device for quickly testing the color coordinates of a diffusion plate. Background Art
[0002] The quantum dots in the quantum dot diffuser plate generate red and green light when stimulated by a blue LED. These light, mixed with some of the blue light transmitted through the plate, creates white light, enhancing the color gamut of LCD displays to over 110% NTSC. Currently, reliability testing of the red and green quantum dots in the quantum dot diffuser plate involves placing a test plate between the miniLED module and the brightness enhancement film. Color coordinates are then measured manually using a handheld color analyzer probe, and their changing trends are analyzed over time. Due to manual operation, inconsistencies in test position, force, and distance are inevitable during both placement of the test plate on the module and testing with the handheld probe. This can lead to errors in color coordinates even when performing simultaneous and consistent testing. This necessitates multiple measurements to obtain an average, which increases time and cost. Prolonged testing can also be harmful to the human body. Summary of the Invention

[0012] Figure 2 It is a schematic diagram of the outer side structure of the utility model. DETAILED DESCRIPTION
[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0014] As shown in the figure, an integrated device for rapid color coordinate testing of a diffusion plate comprises a trough-shaped body 1, two plug-in slots 2, a bracket 3, and a detection probe 4. The trough-shaped body is rectangular with the slot opening facing upward. The plug-in slot 2 is vertically arranged on one longitudinal side of the trough-shaped body 1. Slide slots 5 are provided on each of the longitudinal side walls of the trough-shaped body. The bracket can be slid longitudinally in the slide slots. The detection probe is clamped in the middle of the bracket. When the bracket slides longitudinally, the detection probe on the bracket moves closer to or further away from the plug-in slot. An LED backlight panel 6 is fixedly mounted on the side of the plug-in slot away from the bracket. A brightness enhancement panel 7 and a sample panel 8 to be tested are sequentially connected to the two plug-in slots. The actual number of plug-in slots can be increased or decreased according to actual needs.
[0015] The middle part of the bracket 3 is provided with an elastic clamp 33 for clamping the detection probe. The elastic clamp is in an upwardly open arc shape. The detection probe can be easily installed in the elastic clamp and can also be removed for calibration and maintenance.
[0016] The bracket 3 includes a cross bar 31 and two vertical bars 32 fixedly connected to the two sections of the cross bar. The upper and lower parts of the longitudinal side walls of the trough-shaped body 1 are respectively provided with slide rails 11, and the upper and lower ends of the two vertical bars slide in the corresponding slide rails respectively; the two sections of the cross bar pass through the middle of the vertical bar and slide in the slide groove to form a sliding end, and the sliding end is threadedly connected with a fastening bolt 12 located on the outside of the slide groove.
[0017] The outer side of the longitudinal side wall of the groove-shaped body is provided with a displacement scale 7 located on one side of the sliding groove, which is used to determine the longitudinal position of the bracket.
[0018] The example application operation is as follows:
[0019] Step 1: Connect the LED backlight panel to the power supply and wait for 5 minutes until the blue light stabilizes;
[0020] Step 2: Turn on the color analyzer and calibrate the detection probe;
[0021] Step 3: Fix the detection probe on the bracket;
[0022] Step 4: Loosen the fastening bolts, move the guide rail bracket to the corresponding scale, and tighten the fastening bolts. At this time, the distance between the front end of the probe and the brightness enhancement board should be kept within 0~5mm;
[0023] Step 5: Insert the sample plate from the slot to the bottom, observe the coordinates on the color analyzer, and record the data.
[0024] This design features a housing that effectively blocks blue light from harming testers. This new device ensures a consistent test environment: test distance, test points, and sample placement, thus avoiding human error. The operating steps are simplified compared to previous devices, saving time and increasing accuracy.
