LIGHT EMITTING DISPLAY APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240257741 titled 'LIGHT EMITTING DISPLAY APPARATUS
Simplified Explanation: The patent application describes a light emitting display apparatus that includes a pixel driving circuit and a gate driver supplying gate signals to the pixel driving circuit. The pixel driving circuit consists of a switching transistor, a driving transistor, and a first light emitting transistor. These components control the current supplied to the light emitting device and the data voltage supplied to the device. The apparatus operates by dividing time into a refresh period and an anode reset period, with the switching transistor turned on only during the refresh period.
- The pixel driving circuit includes a switching transistor, a driving transistor, and a first light emitting transistor.
- The gate driver supplies gate signals to the pixel driving circuit.
- The first light emitting transistor controls the current supplied to the light emitting device.
- The switching transistor controls the supply of data voltage to the light emitting device.
- Time is divided into a refresh period and an anode reset period during operation.
