Touch display device and touch display

Abstract

A touch display device and a touch display are provided. The touch display device includes a touch electrode and a backlight module disposed opposite to the touch electrode. The backlight module includes a backlight film and a backlight iron frame supporting the backlight film. The backlight film is disposed between the touch electrode and the backlight iron frame; and the touch electrode and the backlight iron frame are electrically connected to a touch signal terminal. The touch signal terminal is configured to transmit a touch signal to the touch electrode and the backlight iron frame. The touch electrode and the backlight iron frame receive a same touch signal, thereby eliminating the capacitance coupling effect between the touch electrode and the backlight iron frame, increasing touch sensitivity, and reducing vibration noise of the backlight film. The touch display includes the touch display device, and has advantages of the touch display device.
