Light polarizing-filtering module and touch display screen using same

Abstract

A light polarizing-filtering module comprises a light filtering assembly and a light polarizing assembly. The light filtering assembly comprises a transparent substrate, a first conducting layer and a light filtering substrate. The light filtering substrate comprises light-tight matrixes and colorful light resistors. The first conducting layer comprises a plurality of first electric conduction units which extend in the first direction and are mutually insulated. The first electric conduction units comprise first electric conduction silk-covered wires, wherein the width of the first electric conduction silk-covered wires is 0.2-5microns. The light polarizing assembly comprises a light polarizing plate and a second conducting layer. The second conducting layer comprises a plurality of second electric conduction units which extend in the second direction and are mutually insulated. The second electric conduction units comprise second electric conduction silk-covered wires, wherein the width of the second electric conduction silk-covered wires is 0.2-5microns. The first direction is not parallel to the second direction. According to the light polarizing-filtering module, touch operation, a light polarizing function and a light filtering function can be achieved at the same time. When used in a display screen, the light polarizing-filtering module can directly enable the display screen to have the function of touch control. A touch screen is not needed to be assembled on the display screen. Therefore, reduction of the thickness of an electronic product is facilitated, and meanwhile material and assembly cost are greatly saved.

Description

technical field [0001] The invention relates to a touch screen, in particular to a polarizing-filtering module and a touch display screen using the polarizing-filtering module. Background technique [0002] Touch display devices endow information interaction with a new look, and are extremely attractive new information interaction devices. The development of touch display equipment technology has aroused widespread concern in the information media circles at home and abroad, and has become a rising high-tech industry in the optoelectronic industry. [0003] The traditional touch display device is mainly obtained by combining the touch sensing device and the display device through full bonding or frame bonding. Therefore, a process of laminating the touch sensing device and the display device is required during production, and the obtained touch display device is relatively thick. Contents of the invention [0004] Based on this, it is necessary to provide a polarizing-fil...
