Problems solved by technology

[0006] However, after the current touch panel is attached to the liquid crystal display module, due to the design limitation of the frame (Bezel) or frame tape (Bezel tape) pressing the glass of the liquid crystal panel in the prior art, the appearance of the known touch display device is likely to be random. The white bright line caused by the reflection of the residual glue on the edge of the upper polarizer (that is, the optically transparent glue 26 located in the gap between the upper polarizer and the frame) seen by the user's eyes

Embodiment Construction

[0065] In order to make the above-mentioned objects, features, and advantages of the present invention more apparent, a detailed description will be given below in conjunction with the accompanying drawings.

[0066] Please refer to Figure 3a and Figure 3b , which shows the structure of the polarizer 160 of the first embodiment of the present invention. The polarizer 160 includes a release film 162 , an adhesive layer 164 and a polarizing substrate layer 166 . For example, the polarizing substrate layer may include a polyvinyl alcohol (PVA) body layer, a triacetyl cellulose (TAC) support film and a protective film.

[0067] The adhesive layer 164 is disposed on a surface 166a of the polarizing substrate layer 166, and includes a middle region 182 and a peripheral region 184, the middle region 182 is separated from the peripheral region 184, wherein the middle region 182 of the glue layer 164 is an optical The adhesive layer 164 of the peripheral area 184 can be optically ...

Abstract

The invention discloses a polaroid, a display module, a touch control type display device, and a manufacturing method thereof. The touch control type display device includes a touch control panel; a liquid crystal display module including a liquid crystal panel; an upper polaroid and a lower polaroid which are configured on the first and second surfaces of the liquid crystal panel, wherein the upper Polaroid includes a polarized substrate layer; an adhesive layer which is configured on one surface of the polarized substrate layer and includes a middle area and a periphery area, wherein the middle area and the periphery area are separated from each other, the middle area of the adhesive layer is made of a first optical transparent glue, and the middle area is attached to the liquid crystal panel; a circular frame glue formed between the periphery area of the upper polaroid of the liquid crystal display module and the touch control panel; and a second optical transparent glue fully filled in the circular frame glue. The touch control type display device provided can prevent white bright lines caused by the reflection of the edge residue glue of the upper polaroid, thereby preventing visual difference.

Description

technical field [0001] The present invention relates to a polarizer, in particular to a touch-sensitive display device and a manufacturing method thereof. The polarizer adhesive layer of the touch-sensitive display device includes a middle area and a peripheral area. Background technique [0002] Due to the vigorous development of the high-tech electronic information industry, consumer electronics products have become a necessity in people's daily life, and many consumer electronics products have moved towards the trend of thinner and smaller, especially touch-sensitive devices that combine display and input technologies. The display device has the functions of liquid crystal display and touch input at the same time, and can greatly improve the practical performance of various consumer electronic products. [0003] Generally speaking, in the touch display device, the liquid crystal display module is coated with optical glue, and then the touch control panel is bonded. Thro...
