Description

Polarized light plate structure

Technical field

The present invention has about a kind of Polarizer, is espespecially a kind ofly relatively arranged on the polarized light plate structure that liquid crystal display can reduce manufacturing cost and improve overall yield.

Background technology

Existing personal digital assistant (Personal Digital Assistant, PDA), the electronic product such as palmtop computer (Palm-Sized PC) and information household electrical appliances (Information Appliance), on its display screens mostly all take contact panel as setting party to; This display screens can pass through this Trackpad Presentation Function indicating image and word; User can utilize the conductive bodies such as finger or pointer, and the image and the word that show according to this Trackpad surface click, to input and to operate, so that its operation is humanized; And touch-control screen has been played the part of key player especially in the operation of hommization.

So, now in the development and Design of contact panel, major part is all to adopt embedded type touch control technology to design, all can on display screens, can directly carry out touch-control effect be object.And the current main developing direction of embedded type touch control technology is mainly divided into On-Cell and two kinds of technology of In-Cell, wherein On-Cell technology is that (S e n s o r) is produced on panel color optical filter (Color Filter together with Y-axis induction electrode by the X-axis induction electrode of projected capacitive touch technology, CF) the back side, and then be integrated into the structure of colored filter.

In-Cell technology is that X-axis induction electrode and Y-axis induction electrode are inserted to the structure of LCD Cell, in other words, be exactly In Cell Touch technology be that touch-control sensing electrode member is integrated in the glass substrate of display panel, make display panel itself just possess touch controllable function, therefore do not need to carry out in addition and single contact panel laminating or the processing procedure of assembling.

But, no matter it all arranges plural induction electrode (being X-axis induction electrode and Y-axis induction electrode) in top glass substrate or the lower glass substrate of LCD display panel In Cell Touch technology or On Cell Touch technology, this not only increases cost, and in manufacture process because of between X-axis induction electrode and Y-axis induction electrode must build bridge, make to need multiple tracks processing procedure light shield, increase processing procedure program so that cause, and then also easily cause process rate to reduce and the raising of processing procedure cost, therefore the space that, known touch control display apparatus is still improved.

The above, known technology has following shortcoming:

1. process rate reduces;

2. processing procedure cost improves.

Therefore, how to solve above-mentioned public problem and disappearance, the inventor who is this case desires most ardently to the relevant manufacturer that is engaged in the industry the direction place that research improves.

Summary of the invention

For this reason, for solving the shortcoming of above-mentioned known technology, fundamental purpose of the present invention is to provide a kind of polarized light plate structure that reduces manufacturing cost and improve overall yield.

For reaching above-mentioned purpose, the invention provides a kind of polarized light plate structure, comprise a transparency carrier, one induction electrode, one Polarizer and one first insulation glue-line, described transparency carrier has the second side of one first side and contrary this first side, and this induction electrode is coated in the second side of this transparency carrier, and this Polarizer has one the 3rd side and one the 4th side, the described induction electrode of the corresponding laminating of described the 3rd side, and this first insulation glue-line is arranged between this induction electrode layer and Polarizer, by this, when described polarized light plate structure is relatively arranged on a liquid crystal display, this liquid crystal display possesses touch-control input and functipnal capability, and can reach effect person who reduces manufacturing cost and improve overall yield.
