Title: Liquid crystal display and method for inspecting pixels thereof
Inventor: IWASA TAKAYUKI
IPC: G09G3/36
Filed: 2012-10-17
Abstract: The present invention enables pixels to be made smaller than pixels that use two Static Random Access Memory (SRAM) modules in a pixel, and enables pixel inspections to be accurately performed. When a pixel inspection commences, a switch (13B) is switched on, a point c on a pixel (12B) is pre-charged to an intermediate voltage low level, and the voltage at a point d of the pixel (12B) is preset to a high level. In this state, if a high level test signal is written to a column data line (d 1 ) and the data at point a is set to a high level, the voltage at a point b will attempt to change to a low level. In this case, the voltage at point b and point d will change from VDD to a more intermediate potential than GND in a GND voltage range. Said intermediate potential is on a lower potential side than an inversion threshold voltage of an inverter; thus, the voltage at point b and point d is in a state that easily inverts to a low level side. When the switch (13B) is switched off, the voltage at point d is simultaneously set to a low level, and the potential of a column data line (d 2 ) and point c of the pixel (12B) change to a high level.
