Problems solved by technology

[0003] However, in the touch display panel, the reset potential received by the touch sensing circuit will be different due to the effect of RC loading in the panel, thus giving way to the reset potential at the end of the signal transmission path It is different from the potential of the reset potential at the front end of the signal transmission path, so that when the reset potential is applied to the touch sensing circuit and the subsequent output voltage is generated, the output voltage at the front end of the signal transmission path will be greater than that at the end of the signal transmission path Output voltage, causing misjudgment of touch operation

Abstract

An induction circuit includes an energy storage unit, a light sensing unit and a charging unit. The light sensing unit is electrically coupled to the energy storage unit for sensing a first color light, and presents a corresponding conduction state according to the intensity of the sensed first color light to control the discharge of the energy storage unit, and is used for The energy storage unit is reset according to the conduction of the control signal. The charging unit is electrically coupled to the energy storage unit, and charges the energy storage unit during the reset process of the energy storage unit. A touch sensitive panel is also disclosed herein.

Description

technical field [0001] The disclosure relates to a touch-sensitive panel, and in particular to a sensing circuit in the touch-sensitive panel. Background technique [0002] Generally speaking, for a light-sensitive touch display, it mainly uses the light sensor to generate corresponding induced currents according to different light intensities, and uses the difference in the magnitude of the different induced currents as the light intensity perceived by the light sensor. basis, and then make a touch judgment. For example, when the light sensor is touched by a finger, illuminated by ambient light and touched by a light pen, it will generate different induced currents respectively, and when the light intensity received by the light sensor is high, the induced current will also be increases, and the different induced currents can be converted into output voltages through the integrator circuit, so as to judge whether there is a touch operation. [0003] However, in the touch ...
