Light-Emitting Diode Displays - A simplified explanation of the abstract

This abstract first appeared for US patent application 18513132 titled 'Light-Emitting Diode Displays

Simplified Explanation

The patent application describes a display system with pixels that each contain seven transistors, a capacitor, and a light-emitting diode. The display driver circuitry supplies data and control signals to the pixels, with each pixel having first and second emission enable transistors coupled in series with a drive transistor and the light-emitting diode. The gate driver circuits provide different gate line signals to different rows of pixels, with varying strengths and supplemental gate line loading structures.

• Each pixel in the display system contains seven transistors, a capacitor, and a light-emitting diode.

Original Abstract Submitted

A display may have an array of pixels. Display driver circuitry may supply data and control signals to the pixels. Each pixel may have seven transistors, a capacitor, and a light-emitting diode such as an organic light-emitting diode. The seven transistors may receive control signals using horizontal control lines. Each pixel may have first and second emission enable transistors that are coupled in series with a drive transistor and the light-emitting diode of that pixel. The first and second emission enable transistors may be coupled to a common control line or may be separately controlled so that on-bias stress can be effectively applied to the drive transistor. The display driver circuitry may have gate driver circuits that provide different gate line signals to different rows of pixels within the display. Different rows may also have different gate driver strengths and different supplemental gate line loading structures.
