GAP-type low-temperature polycrystalline silicon thin film transistors for light sensing photo-transistor application

Conference Dates

May 15-18, 2023


Recently, ultra-high resolution with biometric recognitions such as fingerprint sensing has been a major trend throughout the whole display industry. In order to meet the needs of high screen ratio, high sensitivity to read out, low temperature polycrystalline silicon (LTPS) thin film transistor (TFT) is considered one of the candidates for sensing application. Unlike photodiode, LTPS photo-transistor structured as transistor makes it possible to sensing under different region (off-state or on state) with relatively small sensing area.
