2. Description of 480x480 Round touch display
ChengHao Display model CH210WV01A-CT is a color active matrix thin
film transistor (TFT) liquid crystal display (LCD) that uses
amorphous silicon TFT as a switching device. This model is composed
of a capacitive touch panel, a TFT LCD panel, a driving IC, a high
brightness back-light, a capacitive touch panel and FPC.
This TFT LCD has a 2.1 (Round screen) inch diagonally measured
active display area with 480*480 resolution.
This circular touch panel is capacitive (CTP), using CST830 as a
driver IC to communicate with other components via I2C interface.
Support multi-touch.
The driving IC is the ST7701S and can display 65K colors by 3line
SPI or R.G.B. signal input. The driver is mounted on the glass and
the interconnection via FPC including components to drive the
display module. Support RGB interface.
In addition, FPC can also be customized according to customer
requirements, such as modifying back-light and CTP structure,
interface definition, etc.
RoHS Compliance & Halogen Free.

6. FAQ
Q1: Do you accept customization displays and touch screens?
A: Sure, you can customization the FPC,Backlight and the touch
screen.
Q2: What type of interface is your display screen?
A: Small sized of displays generally support
SPI,MCU,RGB,MIPI.Medium sized displays generally support
LVDS,MIPI,EDP.Different specifications use different interfaces.
Q3: Do you used capacitive touch screen or resistive touch screen.
A: We have capacitive touch screen and resistive touch screen .
Q4: What is your sample policy?
A: If there is stock,you can sample at any time,if there is no
stock,it will take some time,and then wait for the materials to
come back to sample. But the customer needs to pay the sample fee
and express fee.
