Multi-touch liquid crystal capacitor screen

Abstract

The invention relates to a multi-touch liquid crystal capacitor screen. The multi-touch liquid crystal capacitor screen comprises a first transparent induction layer, a second transparent induction layer and a capacitor monitoring circuit, wherein the first transparent induction layer comprises a plurality of first electrode wires arranged along a first direction; each first electrode wire is formed by a plurality of diamond electrode units which are orderly connected end to end via angles; diagonal lines of the electrode units on each first electrode wire are collinear; the second transparent induction layer comprises a plurality of second electrode wires arranged along a second direction; each second electrode wire is formed by a plurality of diamond electrode units which are orderly connected end to end via the angles; the diagonal lines of the electrode units on each second electrode wire are collinear; the firs electrode wires and the second electrode wires are staggered and attached to one another; and the first electrode wires and the second electrode wires are respectively connected with the capacitor monitoring circuit. According to the multi-touch liquid crystal capacitor screen, the transparent induction layers in two directions are adopted for inducing and computing corresponding coordinates of a plurality of touch points. The multi-touch liquid crystal capacitor screen is simple in structure, and convenient to popularize; the difficulty of the fabrication technique is lowered, and the cost is also reduced.

Description

technical field [0001] The invention relates to the technical field of computer peripheral equipment, in particular to a multi-touch liquid crystal capacitive screen. Background technique [0002] With the development of science and technology, the technology of liquid crystal display is getting higher and higher, and the computer has changed from the previous CRT to the current liquid crystal display, and then from a simple liquid crystal display to a touch display; Apple's IPAD computer relies on its The multi-touch function makes the IPAD computer more convenient to use. The design of the current multi-touch screen is mostly based on Apple's technology. And the detection line, the intersection of the driving line of each row and the detection line of each column needs to be scanned and detected separately. The number of scans is the product of the number of rows and the number of columns. , requires very fine; thus requires a high degree of fine manufacturing process, w...

[0002] With the development of science and technology, the technology of liquid crystal display is getting higher and higher, and the computer has changed from the previous CRT to the current liquid crystal display, and then from a simple liquid crystal display to a touch display; Apple's IPAD computer relies on its The multi-touch function makes the IPAD computer more convenient to use. Most of the current multi-touch screen designs are based on Apple's technology. The capacitive touch screen device structure of its design adopts the interactive capacitive type. And the detection line, the intersection of the driving line of each row and the detection line of each column needs to be scanned and detected separately. The number of scans is the product of the number of rows and the number of columns. , requires very fine; thus requires a high degree of fine manufacturing process, which makes the cost very high
