Problems solved by technology

from figure 1 It can be seen that with the increase in the number of resistive touch screen lines, the number of conductive strips will increase, and the difficulty of forming the strip-shaped sensing electrodes will also increase. It can be seen that not only the manufacturing cost of the existing resistive touch screen is high, And the production process is more difficult
[0005] In addition, the existing resistive touch screen can only realize single-touch technology, which is not in line with the future development trend

Embodiment Construction

[0032] The basic idea of ​​the present invention is to realize contact positioning through two conductive strips arranged on a single-layer transparent substrate and a strip-shaped sensing electrode arranged obliquely between the two conductive strips, and to set a grounding electrode on the upper layer of the single-layer transparent substrate. transparent conductive layer; wherein, the two conductive strips are composed of a plurality of disconnected small conductive strips.

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] figure 2 It is a sectional view of the resistive touch screen of the present invention, as figure 2 As shown, it includes: a first substrate 1 , a second substrate 5 and a grounded transparent conductive layer 6 . Wherein, the second substrate 5 is the single-layer transparent substrate described above, and the second substrate 5 can be made of the ...

Abstract

The invention discloses a resistance type touch screen which comprises a first substrate and further comprises a second substrate and a transparent electric conduction layer which is grounded. Electric conduction strips are arranged on the two opposite sides of the second substrate respectively, and each electric conduction strip is composed of multiple small electric conduction strips which are disconnected. Strip-shaped induction electrodes are obliquely arranged between the two electric conduction strips. The invention further discloses a touch point positioning method of the resistance type touch screen and a touch display device. By the utilization of the resistance type touch screen, the touch point positioning method of the resistance type touch screen and the touch display device, cost for the resistance type touch screen can be reduced, the manufacturing technology can be simplified, and multi-point touch can be achieved.

Description

technical field [0001] The invention relates to a contact positioning technology in a liquid crystal display, in particular to a resistive touch screen, a contact positioning method thereof, and a touch display device. Background technique [0002] With the development of display technology, touch screens have gradually become popular. The so-called touch screen refers to the touch with a finger or a special pen tip on the display panel to complete the point. If it is classified, the finger touch belongs to the finger touch type, and the pen tip touch belongs to the pen tip touch type. Among them, the pen-tip touch screen is mainly used for pictures or handwritten characters that require high precision; while the finger touch screen is used for occasions that do not require high stroke precision. The finger-touch touch screen does not need a special pen, but only needs to directly touch the display panel with a finger to complete operations such as input, which virtually sh...
