HOTDISPLAY's 2.1-inch 540×540 In-Cell round TFT, for example, integrates display and touch using an AXS15260D controller and supports 24-bit RGB display plus I2C touch communication.
| Feature | Conventional Touch | In-Cell TFT |
|---|---|---|
| Touch structure | Separate layer | Integrated |
| Module thickness | Higher | Lower potential |
| Optical layers | More | Fewer |
| Parallax | More noticeable | Reduced |
| Integration | Conventional | Highly integrated |
| Design flexibility | High | Application-dependent |
Useful when internal product space is limited.
Fewer optical layers can improve transmission and reduce visual parallax.
Display and touch functionality are closely integrated.
An integrated architecture can simplify the overall display assembly.
