What is In-Cell?

In-Cell is the core technology of this type of screen, which means embedding the touch sensing layer directly into the interior of the liquid crystal panel.

Compared with traditional screens, it has the following main advantages:

Ultra-thin design: Without the need for an independent touch panel, the total thickness of the module can be controlled at around 3.16mm.

Optical performance is superior: It reduces light refraction, has a higher light transmittance, makes the picture more transparent, and eliminates parallax.

More sensitive touch: The touch response is quick and precise, and it supports smooth multi-touch functionality.

More reliable structure: Integrated design, internal components are less likely to loosen or get dusty. It is more stable in environments with strong vibrations and significant temperature differences.

Product Features

1. High‑Resolution Circular Display – a Cut Above the Rest

Hongjia's 2.1 inch round LCD Screen with 540*540 incell delivers a pixel density far exceeding common 320×320 or 400×400 round panels. Text appears crisp and icons are razor‑sharp, making it ideal for smartwatches, wearables, handheld devices, and other products that demand fine visual detail.

2. Multiple Interface Options for Cost‑Effective MCU Integration

This 2.1 inch round LCD Screen supports QSPI, SPI, MCU, and RGB interfaces, allowing direct connection to low‑cost microcontrollers without requiring expensive main processors. This flexibility significantly reduces overall system cost for budget‑sensitive designs.
