Abstract

The invention discloses an organic light emitting diode display device, which comprises a gate driver, a source driver, a plurality of pixel units and a plurality of infrared units, wherein the gate driver is used for generating a scanning signal; the source driver is used for generating a data signal; each pixel unit comprises a first transistor, a drive circuit and an organic light emitting diode; each infrared unit comprises an infrared light emitting area and an infrared light sensing area; the first transistor is used for conducting the data signal when receiving the scanning signal; the drive circuit is used for generating drive current according to a voltage difference between a power signal and the data signal; the organic light emitting diode is used for generating light rays according to the drive current; the infrared light emitting area is used for emitting infrared rays; and the infrared light sensing area is used for sensing the infrared rays reflected by a reflector.

Description

technical field [0001] The invention relates to an organic light emitting diode display device, in particular to a touch-sensitive organic light emitting diode display device. Background technique [0002] Displays with advanced functions have gradually become an important feature of today's consumer electronics products. Among them, organic light-emitting diode display devices have gradually become a part of various electronic devices such as televisions, mobile phones, personal digital assistants (PDAs), digital cameras, computer screens or notebook computer screens. Displays with high-resolution color screens are widely used. [0003] Different from the common OLED display devices on the market, which utilize the voltage applied to the liquid crystal pixels to determine the pixel brightness, the organic light emitting diode display (Organic Light Emitting Display, OLED) luminous intensity is determined by the forward bias current of the LED to determine the pixel brightne...
