Optical display with touch induction structure

Abstract

The invention relates to an optical display with a touch induction structure. The display comprises a thin film transistor array substrate, an opposite electrode substrate arranged above the thin film transistor array substrate, an electrode plate arranged between the thin film transistor array substrate and the opposite electrode substrate, a plurality of spacers arranged between the opposite electrode substrate and a second conducting surface of the electrode plate, and a display layer arranged between the thin film transistor array substrate and the first conducting surface of the electrode plate. Due to external force applied on the opposite electrode substrate, at least one first electrode in the opposite electrode substrate contacts the second conducting surface of the electrode plate, and the voltage is changed, so that the touch induction function is achieved.

Description

technical field [0001] The invention relates to an optical display, in particular to an optical display with a touch sensing structure. Background technique [0002] figure 1 It is a common liquid crystal display structure with touch function, which includes a display panel 10 and a touch panel 12, wherein the display panel 10 has upper and lower glass substrates 10a, 10b, and electrode structures are provided on the inner surfaces of each substrate as The control drives the liquid crystal to twist and use. The touch panel 12 is stacked on the outside of the upper glass substrate 10a, and the components include upper and lower glass substrates 12a, 12b. The touch panel 12 is also provided with electrode structures on the inner surface of the substrate. , used as a touch sensor. Due to the use of a plurality of glass substrates, the aforementioned structure not only increases the cost, but also makes the overall thickness of the liquid crystal display appear thicker, and th...

Problems solved by technology

The aforementioned structure uses multiple glass substrates, which not only increases the cost, but also makes the overall thickness of the liquid crystal display appear thicker, and the weight is slightly heavier, which is contrary to the trend of the development of the display towards the direction of thinner and shorter.

[0003] Also, if figure 2 As shown, when the touch panel 12 is used in combination with the electronic paper 14, although it has the function of touch operation, because the upper and lower glass substrates 12a, 12b of the touch panel 12 are rigid structures, it is difficult to match it with the electronic paper 14. When in use, the electronic paper 14 will lose its flexibility
