In-cell VS on-cell: Which screen manufacturing process is better?

Both InCell and OnCell screens have a structure of protective glass layer + display panel layer, one less touch layer, thinner and lighter. Has the touch layer disappeared? InCell and OnCell screens integrate the touch layer and display panel, which is the key to distinguishing InCell and OnCell screens.

What is incell?

In-cell is composed of glass cover plate, front polarizer, touch layer + LCD, rear polarizer and backlight. In-cell places the ITO touch film under the upper glass substrate of the display panel, which is generally connected with the liquid crystal layer. Fusion together, the representative model is Apple’s iPhone5.

What is oncell?

Ordinary LCD technology is composed of protective glass, touch layer, air layer and display layer. On-Cell puts the ITO touch film on the upper glass substrate of the display panel, reducing the air layer and touch layer. Samsung Galaxy S2 That’s what it did, with a screen thickness of 8.49mm.

incell VS oncell

1. Visual EffectsIn theory,

in-cell makes the screen one less layer, and the screen picture is clearer than the on-cell screen.

 

2. Thickness

In-Cell is lighter and thinner than On-Cell.

3. Screen Strength

On-Cell is more resistant to falling than In-Cell. In-Cell fuses the touch layer with the liquid crystal layer. If there is a problem with the touch screen, the display panel must be replaced together.

4. Production difficulty

Early In-Cell is more difficult to control production than On-Cell. As the In-Cell manufacturing process matures, both In-Cell and On-Cell production control technologies tend to be stable.

5. Touch Sensitivity

The In-Cell screen directly fuses the touch layer and the liquid crystal layer together, and the sensing noise is large, and a special touch chip is required for filtering and correction processing.

6. Yield

The yields of In-Cell and On-Cell screens are already at the same level, and large-scale shipments are not a problem.

Summarize

On-Cell has an additional touch layer, the thickness will increase to a certain extent, and the display effect will be limited. In-Cell embeds a touch sensor in the pixel, and the area available for display will be reduced, which will lead to image quality degradation to a certain extent, but this is not a serious problem and can be compensated by using a touch chip. If it continues like this, whether it is G+G or G+F, or OGS will eventually be replaced by On-Cell, and On-Cell is just a transition of In-Cell, and only In-Cell will survive in the end.
