Embodiment 1

[0026] Embodiment 1 provides a touch-sensitive liquid crystal display device, such as image 3 As shown, the liquid crystal display device 100 mainly includes a backlight module 10 and a liquid crystal panel 20 disposed opposite to each other. The backlight module 10 is used to provide backlight to the liquid crystal panel 20 so that the liquid crystal panel 20 displays images.

[0027] Wherein, the liquid crystal panel 20 includes a first glass substrate 21, a second glass substrate 22 and a liquid crystal layer 23 arranged between the first glass substrate 21 and the second glass substrate 22, and the first glass substrate 21 faces the One side of the liquid crystal layer 23 is provided with a thin film transistor array 24, and the side of the second glass substrate 22 facing the liquid crystal layer 23 is provided with a color filter 25, and the second glass substrate 22 is also stacked with Cover glass (CoverLens)30. The liquid crystal panel 20 in this embodiment is a sur...

Embodiment 2

[0031] The difference between this embodiment and Embodiment 1 is that the liquid crystal panel in this embodiment is an in-cell (In-Cell) touch display panel. Specifically, as Figure 4 As shown, the touch electrode structure 40 in the liquid crystal panel 20 is disposed on the first glass substrate 21 and located between the liquid crystal layer 23 and the thin film transistor array 24 . Further, in this embodiment, the first polarizing film 50 is the same as that in Embodiment 1, and the second polarizing film 60 is bonded to the second glass substrate 22 away from the liquid crystal layer 23 through a coating process. side. Of course, the second polarizing film 60 can also be coated and bonded on the cover glass 30 .

Embodiment 3

[0033] The difference between this embodiment and embodiment 2 is that, as Figure 5 As shown, the touch electrode structure 40 in the liquid crystal panel 20 is disposed on the second glass substrate 22 and located between the second glass substrate 22 and the color filter 25 . Further, in this embodiment, the first polarizing film 50 is the same as that in Embodiment 2, and the second polarizing film 60 is combined on the cover glass 30 through a coating process. Certainly, the second polarizing film 60 may also be coated and bonded on the second glass substrate 22 .

Abstract

The invention discloses a touch liquid crystal display device which comprises a backlight module and a liquid crystal panel which are oppositely arranged. The liquid crystal panel comprises a first glass substrate, a second glass substrate and a liquid crystal layer arranged between the first glass substrate and the second glass substrate; the side, facing the liquid crystal layer, of the first glass substrate is provided with a thin film transistor array, the side, facing the liquid crystal layer, of the second glass substrate is provided with a color filter, and the second glass substrate is provided with cover plate glass; a touch electrode structure is arranged in the liquid crystal panel. The touch liquid crystal display device is characterized in that the side, far away from the liquid crystal layer, of the first glass substrate is combined with a first polarizing film through film coating, and the side, far away from the liquid crystal layer, of the second glass substrate or the side, facing the second glass substrate, of the cover plate glass is combined with a second polarizing film through film coating. The invention further discloses electronic equipment with the touch liquid crystal display device.

Description

technical field [0001] The present invention relates to the field of liquid crystal display technology, in particular to a touch-sensitive liquid crystal display device and electronic equipment including the touch-sensitive liquid crystal display device. Background technique [0002] With the rapid development of display technology, touch screen panels (TouchScreenPanel) have gradually spread throughout people's lives. According to the composition structure, the touch screen can be divided into: an add-on touch screen (AddonModepanel), a surface touch screen (On-CellTouchPanel) and an in-cell touchscreen (In-CellTouchPanel). Among them, the plug-in touch screen is produced separately from the touch screen and the liquid crystal display, and then bonded together to form a liquid crystal display with touch function; The built-in touch screen is to embed the touch electrodes of the touch screen inside the liquid crystal display (the touch electrodes are prepared in the array s...
