DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18528761 titled 'DISPLAY DEVICE
Simplified Explanation
The patent application describes a display device that includes various lines and drivers to control the emission of light from a subpixel. The device utilizes PWM and PAM signals to control the emission of light from the light-emitting element.
- The display device includes a scan write line, a PWM emission line, a PAM emission line, a sweep signal line, a first data line, a second data line, and a subpixel connected thereto.
- The device includes a light-emitting element, a first pixel driver to supply a control current to a node based on the first data voltage and the PWM emission signal, a second pixel driver to generate a driving current based on the second data voltage and the PWM emission signal, and a third pixel driver to supply 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.
