DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240112626 titled 'DISPLAY DEVICE
Simplified Explanation
The patent application describes a display device that includes various components to control the emission of light from a subpixel. The device utilizes pulse-width modulation (PWM) and pulse-amplitude modulation (PAM) signals to control the current supplied to the light emitting element.
- Scan write line, PWM emission line, PAM emission line, sweep signal line, first data line, and second data line are connected to the subpixel.
- The display device includes a light emitting element and three pixel drivers - first, second, and third.
- The first pixel driver supplies a control current to a node based on the first data voltage and the PWM emission signal.
- The second pixel driver generates a driving current based on the second data voltage and the PWM emission signal.
- The third pixel driver supplies the driving current to the light emitting element based on the PAM emission signal and the voltage of the node.
- The PWM emission signal consists of multiple PWM pulses, while the PAM emission signal consists of multiple PAM pulses, with the number of PWM pulses being greater than the number of PAM pulses.
