Abstract

The invention discloses an embedded touch screen and a liquid crystal display apparatus comprising the same. The embedded touch screen is especially suitable for an ultrathin display with an array substrate located on the front surface (the upper surface) and a color film substrate located on the back surface (the lower surface), and can achieve the effects of reducing metal reflection and enhancing image display. The liquid crystal display apparatus comprises the array substrate and the color film substrate arranged oppositely, and a liquid crystal layer located between the array substrate and the color film substrate; in the array substrate, a conductive light shield layer and an interlayer insulation layer are prepared in sequence before a scanning line metal layer is prepared; the conductive light shield layer consists of a plurality of mesh electrodes; the touch screen takes scanning lines or data lines as driving electrodes and takes the mesh electrodes as induction electrodes; the mesh electrodes and the driving electrodes are crossly arranged; and a touch function is realized through driving of a touch driving IC.

Description

technical field [0001] The invention relates to an embedded touch screen and a liquid crystal display device including the embedded touch screen, belonging to the technical field of touch display. Background technique [0002] As an input medium, a touch panel forms a touch display screen together with a display screen, and the touch display screen has gradually become a mainstream in the display field. Currently, the most widely used touch screens are an add-on touch screen (Add on Touch Panel) which is hung outside the display screen and an in-cell touch screen (In cell Touch Panel) which is embedded in the display screen. The external touch screen display is produced separately from the touch screen, and then bonded together to form a touch display with touch and display functions. With the continuous improvement of optical and electrical characteristics required by flat panel displays, and consumer demand for thinner flat panel displays, high performance, low cost, ultr...
