Abstract

The invention discloses a narrow frame one-chip type capacitor inducting touch screen and a manufacturing method thereof. The narrow frame one-chip type capacitor inducting touch screen comprises a substrate, a plurality of touch control units, a color layer, a plurality of electrodes, a plurality of touch control unit wires, a plurality of electrode wires and a plurality of electric conductors, wherein an array of the touch control units is formed by the touch control units; the color layer is used for forming a non-visual area of the capacitor touch screen and is provided with a plurality of through holes; the electrode wires and the touch control unit wires are electrically connected in the corresponding through holes through the corresponding electric conductors. According to the narrow frame one-chip type capacitor inducting touch screen, the electric conductors can completely cover the through holes, and therefore the light leakage problem caused by the through holes can be avoided. The electric conductors and the electrode wires are arranged in a staggered mode, more electrode wires can be arranged in a frame with a certain width, and therefore the requirement for the narrow frame of the capacitor screen can be met.

Description

technical field [0001] The invention relates to the field of capacitive sensing touch screens, in particular to a narrow-frame single-chip capacitive sensing touch screen and a manufacturing method thereof. Background technique [0002] The structure of the monolithic capacitive sensing touch screen is mainly to coat a transparent film conductor layer on the glass screen, such as an ITO (indium tin oxide) layer, and an array of touch units is formed on the conductor layer. A plurality of electrodes connected to the touch pattern are formed on the side to connect with an external control circuit to apply and extract electrical signals to the array of touch units. When touching the screen, due to the electric field of the human body, a coupling capacitance will be formed between the finger and the touch unit. By calculating the ratio and strength of the current leaving each electrode, the position of the touch point can be accurately obtained. [0003] figure 1 and 2 Schema...
