Embodiment Construction

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0026] combine figure 1 and figure 2 It can be seen that the display module of the existing liquid crystal display panel includes an upper substrate 1 and a lower substrate 2, wherein a liquid crystal layer (not shown in the figure) is sealed between the upper substrate 1 and the lower substrate 2, and the upper substrate 1 and the lower substrate 2 respectively have a first conductive circuit layer (not shown in the figure) and a second conductive circuit layer (not shown in the figure). The conductive ci...

Abstract

The invention provides a liquid crystal display panel comprising a touch sensing module and a display module. The touch sensing module comprises a first conducting circuit layer, the display module comprises a second conducting circuit layer, the liquid crystal display panel further comprises a flexible printed circuit board, the first conducting circuit layer comprises a touch message connection port, the second conducting circuit layer comprises an image information connection port, the touch message connection port is connected to the second conducting circuit layer in a lead manner, the image information connection port is electrically connected with the flexible printed circuit board, and the touch message connection port and the image information connection port are jointly electrically connected to the flexible printed circuit board. Dual functions of touch and display can be realized by one-time FOG (FPC on glass) lamination on a lower substrate, manufacture procedures are simplified, production yield and mass productivity are improved, and poor display of the display panel due to twice FOG binding in adjacent areas of the lower substrate of the display panel is avoided.

Description

technical field [0001] The present invention relates to a liquid crystal display device, and more specifically, to a liquid crystal display panel and a preparation method thereof. Background technique [0002] The on-cell liquid crystal display panels that appear on the market now include touch sensing modules and display modules. On the surface, the touch sensor layer detects the change of capacitance after the finger touches through the conductive circuit (ITO circuit), and then completes the identification of the touch control position. In order to complete the sensing and display pattern at the same time, the liquid crystal display panel needs to be placed under the liquid crystal display panel first. A flexible circuit board for transmitting display pattern information is bound on the substrate, and then a flexible circuit board for transmitting sensing touch information is bound on the upper substrate. [0003] figure 1 Shows the structure of the liquid crystal displ...
