Problems solved by technology

However, when the difference between the sensing signal of the illuminated state and the sensing signal of the non-illuminated state is not large, the touch device may make a misjudgment, causing the user to cover the touch panel while the touch device generates a touch judgment, or the touch device uses a light pen but no touch response

Abstract

A light-sensitive touch device and method. The light-sensitive touch device used in a touch panel includes a plurality of light-sensitive circuits, a plurality of control reading switches and an output unit. The light sensing circuit is used to output light sensing signals respectively; the control reading switch is electrically connected to one of the light sensing circuits respectively, and receives the control reading signal respectively, wherein the control reading switch sequentially controls the reading signal according to It is turned on at the opening time to receive and output the light sensing signal from the light sensing circuit, and the opening times of at least two control reading switches overlap; the output unit is electrically connected to the control reading switch to receive the light sensing signal and output the reading Send out a signal.

Description

technical field [0001] The present invention relates to a touch device, in particular to a light-sensing touch device applied to a touch panel. Background technique [0002] In recent years, tactile man-machine communication interfaces (such as touch panels) have been widely used. With the gradual diversification of touch panel sizes, the touch sensing technology of large-size touch panels is becoming more and more important. However, the signal generated by the touch action in the large-size touch panel will become smaller during the transmission process, making it difficult for the touch device to determine the occurrence of the touch action. [0003] Generally speaking, the sensing signals of the traditional light-sensing touch device are different in the illuminated state and the non-illuminated state, and the touch device judges whether a touch action occurs based on the signal difference. However, when the difference between the sensing signal of the illuminated state...
