Problems solved by technology

[0003] However, currently there are TDDI products for mobile phone products, but for TDDI products, there are currently situations where the surrounding capacitance is relatively high and the surface content value uniformity is poor, which makes it difficult to control the capacitance Spec well in the capacitance inspection process. Lead to yield loss, what's more, lead to Touch failure

Embodiment Construction

[0028] During the use of the touch display panel, since peripheral circuits are arranged around the touch circuit (pixel area), capacitance will be generated between the peripheral circuit and the touch circuit, which will cause the capacitance value around the touch circuit to increase, resulting in touch The capacitance around the control circuit is difficult to control, resulting in loss of yield and even failure of touch control. Therefore, the present invention provides a touch display panel 100 .

Abstract

The invention discloses a touch display panel. A touch circuit and a peripheral circuit are arranged on the touch display panel; the peripheral circuit is arranged at the periphery of the touch circuit; a conductive layer suitable to be matched with at least one part of the peripheral circuit to form a capacitor is arranged on the touch display panel; and the conductive layer is electrically insulated from the touch circuit and the peripheral circuit. According to the touch display panel, the conductive layer is arranged on the touch display panel, is set to be suitable to be matched with the peripheral circuit to form the capacitor and is electrically insulated from the touch circuit and the peripheral circuit, so that the peripheral capacitance of the touch circuit can be reduced and the influence of the peripheral circuit in a pixel region on a peripheral capacitance value in the pixel region is reduced.

Description

technical field [0001] The present invention relates to the field of touch technology, and more specifically, to a touch display panel. Background technique [0002] With the development of touch technology, more and more products adopt Touch technology. At present, the most popular touch technology is capacitive touch sensing technology, and capacitive touch technology is divided into self-capacitance and mutual capacitance. technology. Mutual capacitive touch technology is to coat a layer of ITO conductive layer on the glass surface. When the human hand touches the glass surface, the surface capacitance of the Panel changes; the self-capacitive touch technology uses the internal circuit of the Panel to transmit signals and receive signals at the same time. When touched, the capacitance of itself changes, which is tested. [0003] However, currently there are TDDI products for mobile phone products, but for TDDI products, there are currently situations where the surroundi...
