Touch-type liquid crystal display and relevant touch panel thereof

Abstract

The invention relates to a touch-type liquid crystal display and a relevant touch panel thereof. The touch-type liquid crystal display comprises a liquid crystal display panel and a touch panel, wherein the liquid crystal display comprises a first substrate, a second substrate and a liquid crystal layer, the liquid crystal layer is arranged between the first substrate and the second substrate; and the touch panel is arranged at one side of the second substrate far away from the liquid crystal layer, the touch panel comprises a plurality of mutually parallel first electrodes, a second electrode with a plate like structure, and a plurality of spacers, the second electrode is opposite to the first electrodes, and the spacers are arranged between the first electrodes and the second electrode for spacing the first electrodes and the second electrode. The invention can realize multi-point touch.

Description

technical field [0001] The invention relates to a touch-sensitive liquid crystal display and a touch panel used therein, in particular to a liquid crystal display capable of realizing multi-touch and a corresponding touch panel. Background technique [0002] With the development of electronic technology, touch panels, as input devices of flat display devices, have been more and more widely used in various flat display devices, such as liquid crystal displays. At present, touch panels can be mainly divided into three types: resistive, capacitive and sensor. The resistive touch panel is widely used in liquid crystal displays due to its advantages of simple manufacture and low cost. [0003] Currently, a touch panel in a commonly used liquid crystal display usually includes two conductive substrates, an upper and a lower one, and a spacer disposed between the two conductive substrates. The upper and lower conductive substrates can be respectively composed of a substrate and a...

AI Technical Summary

Problems solved by technology

If the user presses two or more touch locations on the touchpad at the same time, the touchpad cannot accurately identify these touch locations

In other words, the current resistive touch panels cannot perform multi-touch, which greatly limits the application of touch displays

[0004] It can be seen that the above-mentioned existing resistive touch panel obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and the general products do not have a suitable structure to solve the above-mentioned problems. This is obviously related. The problem that the industry is eager to solve
