Problems solved by technology

This method can be finely positioned, but the calculation of the control circuit is large. When the ambient temperature and humidity change, the environmental electric field will cause drift, resulting in inaccurate positioning; the analog capacitive touch screen with double-layer sensing electrodes It is composed of two layers of electrodes with multiple parallel electrodes on each layer. The two layers of electrodes are orthogonal to each other. When a person's finger touches the touch screen, the finger and some electrodes on the touch screen form a coupling capacitance, an...

Embodiment Construction

[0035] One of the embodiments of the present invention is shown in FIG. 3 : a touch-sensitive liquid crystal display 300 connected from a display terminal to detect touch leakage current of display screen electrodes. The liquid crystal display 300 is composed of a liquid crystal display 310 , single pole double throw analog switch groups 320 and 330 , display driving circuits 340 and 350 , touch signal circuits 360 and 370 , and a control system 380 . The N rows of ITO electrodes 311 of the liquid crystal display 310 are connected to the fixed ends of the N-bit single-pole double-throw analog switch group 320, and the display drive circuit 340 and the touch signal circuit 360 are respectively connected to the two switching ends of the analog switch group 320. The column ITO electrodes 312 are connected to the fixed ends of the M-bit SPDT analog switch group 330 , and the display driving circuit 350 and the touch signal circuit 370 are respectively connected to the two switching...

Abstract

This invention discloses one touch control plane display device, which connect display screen electrode and touch control signal circuit through analogue switch, wherein, the analogue switch set makes the display screen electrode and display drive circuit switching between display drive circuit and touch control signal circuit to connect them to multiplex display screen electrode by time division method and to integrate touch control screen and display screen from time dimension with touch control function.

Description

technical field [0001] The invention relates to a touch screen and a flat panel display, in particular to a touch type flat panel display. Background technique [0002] At present, flat-panel displays with touch functions are composed of display screens, display drivers, touch screens, touch signal detectors, backlights and other components. Touch screens include resistive, capacitive, electromagnetic, Ultrasonic type and photoelectric type, etc., the display screens include TN / STN liquid crystal display, TFT liquid crystal display, OLED display, PDP display, carbon nanotube display, etc. A flat panel display with a touch screen laminates a separate touch screen and a display screen, detects the plane position of a touch point through the display screen, and then makes the cursor on the display screen follow the touch point. The layering of the touch screen and the display screen makes the touch panel display thicker and heavier and increases the cost; when the touch screen...
