Title:
DISPLAY PANEL AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/032863
Kind Code:
A1
Abstract:
A display panel and a display device. The display panel comprises a plurality of light emitting devices (D1) and a pixel driving circuit for driving the light emitting devices (D1) to emit light. In the pixel driving circuit, a compensation transistor (T3), a first initialization transistor (T4), and a second initialization transistor (T7) are set as oxide transistors, other transistors are set as low-temperature polysilicon transistors, and the characteristic of low leakage current of the oxide transistors and the characteristic of high mobility of the low-temperature polysilicon transistors can be simultaneously used, so that the circuit is more stable.
