Touch screen module with 7 inch capacitive touch panel introduction:
TFT
LCD display 7.0 inch is a color touch screen module which is made with 800RGBx480 resolution, it is RGB interface, and can be also custom make interface to MCU interface, that can be easily controlled via the MCU PIC, AVR, ARM,STM32 system and as the embeded systems as well. its application including Automotive, medical devices, industrial devices, home control system, security devices, POS machines which requires display in high quality and colorful image.
This touchscreen module is 7.0" in diagonal, packed with RGB pixels,
for making very small high-density displays. The 7 inch capacitive touch panel is I2C interface, it is multi touch capacitive touch panel, it can be optiacal bonding or frame bonding on the tft lcd screen.
The
7 inch capacitive touch screen module MLT070W50-CT22 is composed of a TFT-LCD panel, driver IC,
FPC, a backlight unit and 7 inch capacitive touch panel. 6 o’clock
viewing angel display, and built in with controller IC, it supports RGB
interface.

Touch screen module means the touch panel on the lcd screen module or oled screen, we call it tft touchscreen module or oled touch screen. the touch screen have resistive touch panel and capacitive touch panel. the touch panel is stacked on the lcd or oled screen. the conection way have the frame bonding or optical bonding way. the resistive touch panel is one point touch panel, its touch function is via the touch force on the touch panel. capacitive touch screen is multi-point touch panel, such as 5 points touch, 10 points touch or 1 point touch+gesture, the touch panel points is related to the IC controller of capacitive touch panel.
Can i make touch screen module for my screen?
Yes, Maclight could support to add the touch screen for most of our the tft lcd or OLED touch screen in frame bonding or optical bonding connection. we could also custom make the touch screen for difference sizes of tft lcd or OLED touch screen.
