Abstract

The invention discloses a touch display device and a manufacturing method of the touch display device. The touch display device comprises a first substrate, a second substrate, a liquid crystal layer, separated receiving electrodes and first separated transparent electrodes, the first substrate and the second substrate are oppositely arranged, the liquid crystal layer is arranged between the first substrate and the second substrate, the separated receiving electrodes are formed on the first substrate, the first separated transparent electrodes are formed below the receiving electrodes, in the projection direction of the first substrate, on the first substrate and along a display electrode on the second substrate, the first transparent electrodes and the receiving electrodes are separated by insulation layers, and the first transparent electrodes are connected to fixed potentials. When the receiving electrodes and emission electrodes are arranged on the same layer, coupling capacitors between the receiving electrodes and the electrodes on an array substrate and between emission layers and the thelectrodes on the array substrate are shielded. When the emission electrodes are arranged on the array substrate side, coupling capacitors between the receiving electrodes and a common electrode of the array substrate side and coupling capacitors formed between the emission electrodes and the receiving electrodes through the liquid crystal layer are shielded. When liquid crystals deflect, detection signals are not influenced basically, noise caused by frame switching is shielded, and the quality of the touch display device is improved obviously.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a touch display device and a manufacturing method thereof. Background technique [0002] As an input medium, a touch screen provides users with better convenience than a keyboard and a mouse. According to different implementation principles, touch screens can be classified into resistive, capacitive, surface acoustic wave, infrared, etc., and resistive and capacitive touch screen technologies are widely used at present. [0003] Mutual capacitive touch screen, with its high sensitivity and advantages of multi-touch, is becoming more and more popular. The basic principle of mutual capacitive touch screen is: apply voltage on the drive line side, and detect signal changes on the detection line side , the driving line determines the X-direction coordinates, and the detection line determines the Y-direction coordinates. During detection, the X-direction driving lines are sca...
