Problems solved by technology

In this situation, although the input device 12 does not perform touch input, the difference ΔV between the first light-sensing signal V1 and the second light-sensing signal V2 generated by the light-sensing element 10 at different time points may already be greater than a predetermined value. , so the known method will judge that there is a touch input signal, resulting in misjudgment

Abstract

The invention provides a touch-control display panel and a light-induced touch-control unit thereof. The light-induced touch-control unit comprises a first light-induced touch-control element located in a first element zone, and a second light-induced touch-control element located in a second element zone. Both the first light-induced touch-control element and the second light-induced touch-control element are at least partially exposed to environmental light, and the touch-control input judgement of the light-induced touch-control unit is based on the absolute value of the difference value between a first light-induced signal of the the first light-induced touch-control element and a second light-induced signal of the second light-induced touch-control element.

Description

technical field [0001] The present invention relates to a light-sensing touch unit and a touch display panel, in particular to a light-sensing touch unit comprising a first light-sensing touch element and a second light-sensing touch element and a light-sensing touch the touch display panel of the control unit. The touch input judgment of the light-sensing touch unit is based on the absolute value of the difference between the first light-sensing signal of the first light-sensing touch element and the second light-sensing signal of the second light-sensing touch element. Background technique [0002] In today's various types of consumer electronic products, portable electronic products such as tablet computers, personal digital assistants (PDAs), mobile phones (mobile phones), satellite navigation systems (GPS) and audio-visual players have been widely used such as resistive, capacitive Different forms of touch panels, such as touch panel and light-sensitive touch panel, ar...
