Embodiment Construction

[0056] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0057] A method for automatically adjusting Gamma of an OLED CELL panel proposed by the present invention comprises the following steps:

[0058] Step 1, perform routine configuration, calibration and basic function test on the optical tester 4 . This device adopts optical tester 4 as Admesy Hera equipment.

[0059] Step 2, configure white screen and red, green and blue screen adjustment parameters.

[0060] Step 3: Perform waveform conversion and Data voltage binding according to the CELL panel waveform file and pixel lighting principle; the purpose of waveform conversion is to keep the red, green, and blue Data voltages independent of each other for Gamma adjustment. The lighting device 3 used in this device is PG600A.

[0061]Perform waveform conversion and Data voltage binding for each binding point of CELL panel 5, and perform...

Abstract

The invention discloses a Gamma automatic calibration method and system of OLED CELL panels. The method comprises the following steps of: configuring device parameters, a white picture and a red-green-blue picture adjusting parameter; performing wave-type conversion and binding Data voltage according to the CELL panel wave file and the pixel lighting principle; adjusting the Data voltage corresponding to the red, green and blue pictures to adjust the chroma and performing loop execution until the target chromaticity value and the corresponding data voltage value are searched, and performing white picture Gamma adjustment until the current brightness value is within the target brightness value error range; reading back the state brightness and the chroma of each binding point of the CELL panel, and recording and storing the Data voltage value corresponding to each state; inputting the saved Data voltage value to the CELL panel for screen detection. The system comprises a PC, a TEMS, a lighting device, an optical tester and a CELL panel. The Gamma automatic calibration method has the advantages of simple operation, high chroma and high brightness passing rate and high test efficiency, and is convenient for large-scale use in the factory.

Description

technical field [0001] The invention relates to the field of display and testing of liquid crystal CELL panels, in particular to an OLED CELL panel Gamma automatic adjustment method and system. Background technique [0002] In the production process of OLED CELL panels, the intelligent equipment inspection system detects common defects encountered in production based on optical principles. This new type of testing technology has developed rapidly, and many manufacturers have introduced corresponding testing equipment. During automatic detection, the machine automatically scans through the camera, collects images, compares the tested points with the qualified parameters in the database, checks out the defects through image processing, and displays / marks the defects through the display or automatic signs, and repair. [0003] The conventional detection indicators of the intelligent equipment Gamma station are: [0004] (1) The adjustment range includes white, red, green and...
