Abstract

The invention relates to an integrated touch function display screen and a manufacture method thereof. The integrated touch function display screen is characterized by comprising a first substrate, a thin film transistor, a first alignment layer, a liquid crystal molecular layer, a second alignment layer, a plurality of isolation columns, a colorful optical filter layer and a second substrate. The display screen can be manufactured by adopting traditional processes and also can be manufactured by adopting 3D technology, and a touch and display function can be realized if the integrated touch function display screen is provided with a driving and processing assembly. The isolation columns of the invention realizes an isolating and supporting function, and meanwhile, a lead on the second substrate can be connected to the first substrate; and a touch unit is arranged below the display screen to effectively increase a display opening rate. Meanwhile, parts of the processes adopt a 3D printing technology, and the manufacture method is greatly simplified when the manufacture method is compared with a traditional method, multiple complex processes, such as exposure, development, etching and the like, in the traditional processes can be omitted, and production raw materials and the manufacture cost are saved and lowered.

Description

technical field

[0001] The invention relates to a manufacturing method of a touch screen, in particular to an integrated touch function display screen and a manufacturing method thereof, which are applied to display and touch devices. Background technique

[0002] Touch screen operation is a new type of operation, and it tends to replace traditional buttons, mice and keyboards. For the convenience of operation, people use touch screens to replace other input devices as a new operation mode for electronic products. First touch the touch screen installed on the front of the display screen with a finger or other objects, and then the control center analyzes the coordinates of the contact point through the signal of the touch screen and performs control.

[0003] The integrated touch display screen, also known as IN-CELL touch screen, is to set the touch function inside the display panel, which can make the touch screen thinner and has a broad market prospect. Companies such a...
