Embodiment Construction

[0033] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] When conventional PCB automatic detection equipment adjusts the flickering picture of the test display panel, refer to figure 1 , usually the flicker value adjuster 200 is correspondingly arranged on the upper corner of the side of the stage 100 ( figure 1 is the upper right corner), but the measurement of the flicker value adjuster 200 needs to measure the center point of the display panel 900, and the verification of the measurement is also based on the center of the panel. Therefore, in the actual detection operation of the conventional PCB automatic detection equipment, If the flicker value adjuster 200 detection panel is to be stretched out from the upper side of the stage, the central point of the panel must be measured, so the length of the stretching mechanism carrying the flicker value adjuster 200 mus...

Abstract

The invention provides an automatic detection system and a detection method of a frame flicker of a display panel. The system comprises a first carrier, wherein one side in a first direction of a plane where the first carrier is located is opposite to a first lighting mechanism; the first lighting mechanism is used for testing a printed circuit board of the display panel; one end in a second direction of the plane where the first carrier is located is opposite to a first panel positioning mechanism; the first carrier corresponds to a feed arm in a vertical direction; a flicker value adjustor is arranged at a center point of a feed end of the feed arm; the center point of the feed end of the feed arm is aligned to the panel center of the display panel fixed on the first carrier; the flicker value adjustor is used for adjusting common electrode voltage of the display panel to eliminate a frame flicker phenomenon of the display panel; and the detection system can adjust and test a flicker frame directly from the panel center of the display panel from the beginning, so that the adjustment time is shortened.

Description

technical field [0001] The invention relates to the field of liquid crystal panel display, in particular to an automatic detection system and detection method for screen flicker of a display panel. Background technique [0002] The V of the LCD panel com Voltage (common electrode voltage) is the reference voltage for liquid crystal AC drive, V com It must be adjustable in circuit design, because in module engineering, it generally needs to be fine-tuned according to the flickering state of the display. In the module project if V com If the voltage value is outside the specified voltage, the flicker phenomenon (picture flicker phenomenon) will appear on the display panel, and after high temperature aging, there will even be afterimage problems. At this time, the PCB substrate (Printed Circuit Board, printed circuit board) of the display panel must be replaced. ). [0003] Conventional display panel PCB (Printed Circuit Board, printed circuit board) testing equipment is ma...
