Problems solved by technology

[0004] 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 greatly increase, making it difficult to apply to electronic products that require lightness and thinness

[0083] see Figure 16Shown is the sixth embodiment of the organic light emitting diode touch display device of the present invention, which includes the same components as the fourth embodiment, and its difference from the fourth embodiment lies in: the touch sensing of the packaging component 30 The layer 33 , the transparent insulating plate 36 , the quarter wave plate 31 , the polarizer 32 and the glass 34 are sequentially stacked from bottom to top. As far as the manufacturing process is concerned, the touch-sensing layer 33 is first formed on the lower surface of the transparent insulating plate 36, and the quarter-wave plate 31 made of liquid crystal material is formed on the upper surface of the transparent insulating plate 36. A polarizing plate 32 is disposed on the wave plate 31 , and the upper surface of the polarizing plate 32 is covered with glass 34 . Wherein, if the polarizer 32 is made of surface-treated (hardened) material, the glass 34 can be omitted, so as ...

Abstract

An organic light-emitting diode touch display device comprises an organic light-emitting component and a packaging component. The packaging component covers the organic light-emitting component and comprises a quarter-wave plate, a polarizing plate and a touch sensing layer, the quarter-wave plate is made of a liquid crystal layer, and the touch sensing layer is of a single-layer electrode structure. Thus, the organic light-emitting diode touch display device has display, optical antireflection and touch functions at the same time, and the thickness and the weight of the organic light-emitting diode touch display device are reduced effectively.

Description

technical field [0001] 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 [0002] see figure 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 arranged on the substrate 10, and a transparent cover plate 12 covering the top of the organic light emitting module 11, such as glass or transparent 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 ambien...
