Abstract

The invention provides a compound liquid crystal display device, comprising a first basal plate, a second basal plate arranged opposite to the first basal plate, and a liquid crystal layer located between the first basal plate and the second basal plate; the inner side of the first basal plate is provided with a first polaroid, a color-resisting layer, black matrixes and a viewpoint control electrode, the outer side or the inner side of the first basal plate is provided with a touch control circuit layer, the position of the first polaroid is located between the touch control circuit layer and the viewpoint control electrode, and the first polaroid is made of a metal material. The compound liquid crystal display device is additionally provided with a touch control function and a viewpoint switching function, box thickness does not need to be increased additionally, furthermore, interference of a viewpoint switching signal to touch control is reduced, so that the touch control is more sensitive.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a composite liquid crystal display device. Background technique [0002] Liquid crystal display (liquid crystal display, LCD) has the advantages of good image quality, small size, light weight, low driving voltage, low power consumption, no radiation and relatively low manufacturing cost, and occupies a dominant position in the field of flat panel display. The liquid crystal display device includes a color filter substrate and a thin film transistor array substrate oppositely arranged, and a liquid crystal layer sandwiched between them. [0003] Currently, liquid crystal display devices are gradually developing toward wide viewing angles. For example, liquid crystal display devices using in-plane switching (IPS) or fringe field switching (FFS) modes can achieve wider viewing angles. However, in today's society, people pay more and more attention to protecting thei...
