P‐43: Finely Programmable Pulse Width Shift Register for Luminance Control of AMOLED Displays

Abstract

In this paper, we propose a programmable shift register circuit at a low temperature poly‐silicon (LTPS) backplane suitable for high‐resolution and high‐speed displays. The proposed circuit can control the pulse width at a line‐time unit by a start signal, where two additional clock signals were in use compared to the conventional circuit. Smartspice simulation was conducted to verify the feasibility, proving the pulse width controllability at a line‐time unit. The estimated power consumption is lower than the conventional circuit.
