Abstract

The invention discloses an OLED module test system and test method. The test system comprises a program controlled signal source, a program controlled power supply, an upper computer and an AC-DC power supply, wherein an input end of the program controlled signal source is connected with the upper computer, an output end of the program controlled signal source is connected with an input end of the program controlled power supply and an OLED module to be tested, a multi-output end of the program controlled power supply is connected with the OLED module to be tested, and an output end of the AC-DC power supply is connected with the program controlled signal source and the program controlled power supply. According to the OLED module test system and test method, interface signals of four types, namely, LVDS, RGB, MIPI and DP are compatible at the same time, and test requirements for different sizes of LED modules can be met; multiple-power-output can be provided, each power output can be regulated through an independent switch, and the limit to testing the OLED module through a traditional liquid crystal module test system is broken through.

Description

technical field [0001] The invention relates to the field of liquid crystal module testing, in particular to an OLED module testing system and testing method capable of providing multiple power sources and various interface signals. Background technique [0002] OLED (Organic Laser Display) has many advantages such as light and thin, no viewing angle problem, high definition, high brightness, fast response, low energy consumption, etc. At present, OLED is rapidly replacing traditional LCD (liquid crystal display) to become the mainstream technology in the display industry. Liquid crystal display technology developed earlier, and its module display quality detection technology is relatively mature. OLED module production lines generally use traditional liquid crystal module test systems to test the display quality of OLED modules. There is a big difference between the light emitting mechanism and the liquid crystal module. OLED modules have more types of power sources and hig...
