Description

Organic Light Emitting Diode Touch Display Device

technical field

The present invention relates to a display device, in particular to an organic light emitting diode touch display device with a touch function.

Background technique

1, an existing organic light emitting diode (hereinafter referred to as OLED) display 1 mainly includes a substrate 10, an organic light emitting module 11 disposed on the substrate 10, and a transparent cover 12 covering the organic light emitting module 11, for example Glass or clear acrylic (PET) sheet. In addition, the substrate 10 and the periphery of the transparent cover 12 are bonded with a sealant layer 13 to seal the organic light-emitting module 11 between them so as not to be oxidized by moisture. And because the OLED display 1 is a self-illuminating display mode, it has the display characteristics of high contrast and high color saturation indoors or under low ambient light conditions, but if it is placed under a high-illuminance ambient light source, such as receiving an outdoor When the sun shines, since the brightness of the OLED itself is much lower than the ambient light, the external light reflected by the surface of the OLED display 1 will make the user not clearly see the image displayed on the OLED display 1 .

Therefore, in order to solve the above problems, the traditional method is to set an optical film group (not shown) composed of a quarter-wave plate and a polarizer on the transparent cover plate 12 of the OLED display 1, so that the absorption Incident light from the outside world. The quarter-wave plate is traditionally made of a polymer film surface (polyimide, referred to as PI) through uniaxial or biaxial stretching, and its thickness is about several hundred microns. The polarizing plate is traditionally composed of TAC (triacetyl cellulose) film (protective layer), PVA (polyvinyl alcohol) polarizing substrate and TAC film (protective layer) with a total thickness of three layers from tens of microns to hundreds of microns. .

In addition, if the OLED display 1 is to have a touch function at the same time, a ready-made touch sensing module (not shown) can be arranged on the optical film set of the OLED display 1. The volume, thickness and weight of functional OLED displays will be greatly increased, making it difficult to apply to electronic products that require lightness and thinness.
