7'' HDMI Display with Capacitive Touchscreen

Introduction

This is a 7" HDMI display with capacitive touchscreen. It comes with a 7" LCD screen with capacitive touch panel overlay on it. The touch panel supports up to 5 touch points. And it adopts DFRobot USB free-driver technology, no special requirement of drivers. You can use it as easy as keyboard or mouse. It can be directly plugged to PC for touching control. In combination with HDMI HD screen, it can turn a large PC to a tablet immediately.

The screen supports Windows, Linux and MAC OS. It can be used on Lattepanda, Raspberry Pi and other HDMI device. We also make some special hole to make it compatible with Arduino screw hole. You can mount them on the back of the display directly.

There is no need for external power supply for the screen, it can be powered by USB port and HDMI port. The display also supports back light adjustment. It is very convenient to adjust backlight by potentiometer on the back of the display.

Touchscreen with Raspberry Pi

You need to reset resolution to avoid touch differentiation caused by resolution difference between Raspberry Pi and the Touchscreen.

#### remove black borders
disable_overscan=1

#### set specific CVT mode
hdmi_cvt 1024 600 60 6 0 0 0

#### set CVT as default
hdmi_group=2
hdmi_mode=87

NOTE: Windows and MAC operating system can capture resolution automatically, so you don't need to modify any parameter.
