Abstract

The invention discloses an LCD (liquid crystal display) panel and a manufacturing method therefor. The method comprises: S1, SMT (surface mount technology) populating is performed on the LCD panel; S2, a dot screen test is performed on the LCD panel, and data information is burnt into a chip during the process of the dot screen test; S3, an ATE (automatic test equipment) electrical performance test is performed on the LCD panel. According to the invention, chip burning is performed at the stage of the dot screen test, and a burning step is completed after a populating step, so that an improvement on the burn technology, as well as an improvement on confirming conditions after burning, can be realized, burning apparatus and jigs are reduced, and both of time and cost are reduced.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to an LCD display panel and a manufacturing method thereof. Background technique [0002] ginseng figure 1 As shown, the basic process of the manufacturing method of the LCD display panel in the current technology is as follows. First, use the burning fixture to burn the NVM (non-volatile memory) inside the chip (such as PWM IC and P-Gamma IC), and the chip The internal required voltage and setting data are burned into the chip, and then SMT packaging, ATE electrical performance test and point screen test are performed. [0003] In the prior art, it is necessary to use programming instruments and fixtures to program the P-Gamma IC and PWM IC twice before SMT packaging, which will cause a waste of labor and time, resulting in increased costs, and cannot Check in time whether the programming is OK, and also need to control multiple versions of the burning data.
