Do you know what we usually call in-cell, on-cell and OGS? What are their characteristics? the following is a brief explanation for you.
The LCD displays can be divided into three parts according to the structure, from top to bottom, They are protective glass, touch part and screen part. What we call in-cell, on-cell and OGS is just technology in the full paste of these three parts. Generally speaking, for an LCD display, especially an LCD touchscreen, two laminations are required, one lamination is between the protective glass and the touch screen, and one lamination is between the screen and the touch part. According to the way of bonding, it can be divided into two types: full paste and frame paste.
- Different Touchscreen With Their Pros And Cons
- Which Is Better: Resistive Touchscreen Or Capacitive Touchscreen?
Full paste means that the display panel and the touchscreen are glued seamlessly with water glue or optical glue. With the full paste technology, there is no air between the display panel and the touchscreen, which can effectively reduce glass reflection and effectively protect the screen from impurities, reduce moisture damage, and increase the working life of the LCD display.
In-Cell simply speaking, it puts the touch sensor (Sensor) in Cell, that is mean embedding the touch sensor function inside the LCD, putting the IoT film under the glass substrate of the display panel, and fusing it with the liquid crystal. Of course, at the same time, the In-Cell screen must be embedded with a supporting touch IC, otherwise, it is easy to cause wrong touch sensing signals or excessive noise.
On-cell refers to the scheme of embedding the touchscreen between the color filter substrate and the polarizer of the screen, that is, a touch sensor is equipped on the liquid crystal panel.
OGS (one glass solution) is also known as TOL technology, which is currently the main application solution on full-paste LCD capacitive touch screens. OGS is a technology that directly implements the touch sensor on the glass cover. It integrates the touch layer and the protective glass and coats the conductive layer of ITO (indium tin oxide) on the inner side of the protective glass to directly coat the protective glass. This saves a piece of glass and one paste work, so makes the LCD touchscreen thinner and lowers the cost. However, since the OGS protective glass and the touch screen are integrated together, it usually needs to be strengthened first, then coated, etched, and finally cut.
