Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, but these embodiments should not be construed as limiting the present invention.

[0030] Such as figure 1 As shown, the present invention proposes a liquid crystal module chromaticity value acquisition system, including several self-calibration colorimeters 1 arranged in the display assembly line working area A and a spectrometer 2 arranged in the display sample monitoring area B, the spectrometer 2 and Each self-calibration colorimeter 1 is connected to PC3 through a communication data bus.

[0031] The self-calibration colorimeter 1 is used for self-calibration of the chromaticity value according to the spectral radiation curve and correction parameters transmitted by the PC3. After the self-calibration is completed, the spectral data corresponding to the display a on the assembly line station is collected and transmitted to the PC3. The spe...

Abstract

The invention discloses a liquid crystal module chromaticity value acquisition system and method. The system includes several self-calibration colorimeters arranged in the working area of ​​the display assembly line and a spectrometer arranged in the sample monitoring area of ​​the display; the self-calibration colorimeter The chromaticity meter is used for self-calibration of the chromaticity value according to the spectral radiation curve and correction parameters transmitted by the PC. After the self-calibration is completed, the spectral data of the corresponding display on the assembly line station is collected and transmitted to the PC; the spectrometer is used to collect display samples from the monitor in the monitoring area. The spectral radiation curve; the PC is used to calculate the correction parameters of each self-calibration colorimeter, and then receive the spectral data of the corresponding display on the assembly line station collected by the self-calibration colorimeter after the self-calibration is completed. The invention improves the large-scale array application of the colorimeter in a low-cost manner, meets the requirements of the assembly line on speed, precision and cost, and is very suitable for large-scale factory production.

Description

technical field [0001] The invention relates to the technical field of liquid crystal module chromaticity correction, in particular to a liquid crystal module chromaticity value acquisition system and method. Background technique [0002] Liquid crystal module manufacturers use spectrometers or colorimeters to correct the chromaticity value of the display module. Spectrometer colorimeters generally have the advantages of slow speed but high precision. Tri-stimulus value colorimeters have the advantages of fast speed and low cost. But its accuracy is worse than spectrometer. Due to the process differences among filters, tristimulus value colorimeters generally have individual differences in accuracy. In actual use, it is necessary to perform corrections for different screens and generate correction parameters corresponding to each type of screen. For example, ca310 contains 99 channels, and each channel can store the parameters of a type of screen. On the display assembly l...
