Problems solved by technology

However, usually the color filter substrate of the liquid crystal panel does not have enough space for the pressing head to press
In addition, even if the color filter substrate of the liquid crystal panel has enough space for the pressure head to press and use the method of using a smaller indenter, it still needs to increase the bonding structure on the color filter substrate of the liquid crystal panel, making the cost of the entire device improve, but also complicate the manufacturing process of the whole device

Embodiment 1

[0048] Please refer to figure 1 , figure 1 It is a schematic top view of the color filter substrate and the array substrate according to the first embodiment of the present invention. Among them, the color filter substrate 1 is located figure 1 On the left, array substrate 2 is located figure 1 Right. The color filter substrate 1 includes a transparent insulating substrate 11, and the transparent insulating substrate 11 may be a glass substrate or a resin substrate or the like. The transparent insulating substrate 11 (also called the color filter substrate 1 ) has a glue-sealed area 111 . The glue-sealed area 111 is an annular area formed around the periphery of the color filter substrate 1 . The glue-sealing area 111 is used for subsequent coating of frame glue, and the frame glue is used for glue-sealing the color filter substrate 1 and the array substrate 2 together to form a liquid crystal panel.

[0049] In this embodiment, the color filter substrate 1 includes a plu...

Embodiment 2

[0070] Please refer to image 3 , image 3 It is a schematic top view of the color filter substrate and the array substrate according to the second embodiment of the present invention. From image 3 It can be seen from the figure that in this embodiment, most of the structures of the color filter substrate 1 are the same as those of the first embodiment. However, the difference between the color filter substrate 1 of this embodiment and the first embodiment is that the first conductive pad 12 of this embodiment is disposed inside the glue-sealed area 111 located at the upper right corner of the color filter substrate 1 . Similarly, for image 3 The difference between the array substrate 2 in the first embodiment and the array substrate in the first embodiment is that the position of the second conductive pad 22 is changed. In this embodiment, the second conductive pad 22 also falls inside the glue sealing area 211 of the array substrate 2 . Moreover, since the position of...

Embodiment 3

[0075] Please refer to Figure 5 , Figure 5 It is a schematic top view of the color filter substrate and the array substrate according to the third embodiment of the present invention. From Figure 5 It can be seen from the figure that in this embodiment, most of the structure of the color filter substrate 1 is the same as that in the second embodiment, the difference is that in this embodiment the first conductive pad 12 is located in a region other than the glue-sealed region 111 . Specifically, the first conductive pad 12 is located at the upper right corner of the color filter substrate 1 . Likewise, in this embodiment, the second conductive pad 22 on the array substrate 2 is correspondingly located at the upper left corner of the array substrate 2 . In this embodiment, the second signal line 23 on the array substrate 2 is correspondingly arranged in the area other than the glue sealing area 211 , and the area where the second conductive pad 22 is located is the common...

Abstract

The invention discloses an embedded liquid crystal touch control panel, which comprises a color film base plate provided with touch control units, an array base plate opposite to the color film base plate; a liquid crystal layer sealed between the color film base plate and the array base plate, a plurality of first conductive pads located on the inner side of the color film base plate, a plurality of second conductive pads located on the inner side of the array base plate, and a conductive substance, wherein each of the first conductive pads is electrically connected to a first signal line used for transmission of a touch control signal; each of the second conductive pads is electrically connected to a second signal line for transmission of the touch control signal; the conductive substance is located between the first conductive pad and the second conductive pad, the conductive substance enables each of the first conductive pads to be electrically connected with each second conductive pad, and meanwhile enables the first conductive pads to be insulated with each other. The embedded liquid crystal touch panel improves the device integration level.

Description

technical field [0001] The invention relates to the field of touch display, in particular to an embedded liquid crystal touch panel. Background technique [0002] Liquid crystal display (LCD) technology is the first flat panel display technology to enter large-scale industrialization, and is currently a hot technology in the display industry. Since Austrian scientists first discovered the liquid crystal phenomenon in 1888, the epoch-making liquid crystal display came out in 1968. In the following decades, liquid crystal display technology continued to develop. After entering the 21st century, liquid crystal display technology has been further developed, and the development at this stage is mainly reflected in improving display quality, realizing energy saving and environmental protection, and integrating other functions. [0003] Since the world's first resistive touch screen appeared in 1974, touch technology has developed rapidly, and the industry has produced various typ...
