Problems solved by technology
[0004] However, the inventor found that in the prior art, each pixel unit needs to be provided with a thin film transistor T3 that controls whether the OELD in the pixel unit can emit light, which leads to an excessive number of TFTs in the OLED display device and a complicated product structure. The density increases, thereby reducing the aperture ratio of the pixel unit, increasing power consumption, and increasing product defects during manufacturing; since the thin film transistor T3 is located in the pixel unit, it is not maintainable when the thin film transistor T3 is damaged
