Title:
表示装置、その駆動方法及び表示装置用駆動装置
Document Type and Number:
Japanese Patent JP4908844
Kind Code:
B2
Abstract:
A display apparatus may include touch detection circuitry including a light sensing circuit and a physical parameter sensing circuit (e.g., a pressure sensing circuit). The display apparatus may further include processing circuitry implementing a power-saving mode and a normal mode, and configured to generate touch information. An display driver may include a photo sensing circuit and a pressure sensing circuit. An embodiment of the display driver may include: an amplifying unit amplifying a photo sensing signal and a pressure sensing signal; a parallel-to-serial converting unit converting the amplified photo sensing signal and the amplified pressure sensing signal into serial sensing signals; and an analog-to-digital converter converting the serial sensing signals into digital sensing signals, wherein the amplifying unit, the parallel-to-serial converting unit, and the analog-to-digital converter operate in one of a normal mode and a power saving mode according to the pressure sensing signal.
