Abstract

The present invention provides a touch liquid crystal display panel, a CF substrate and a touch display device. The touch liquid crystal display panel includes a TFT substrate, a CF substrate and a liquid crystal layer, the TFT substrate includes multiple rows of grid scanning lines, and the CF substrate includes a Multi-row grid scan lines correspond to multi-row RGB color layers. The display and touch of the touch LCD panel adopts a time-sharing drive scanning method. In the time period, n rows of gate scanning lines are scanned; in the second time period of the cycle, touch detection scanning is performed alternately until one frame of screen display is completed, and gate scanning lines are performed k times in one cycle Scanning, the thickness of the RGB color layer corresponding to the gate scanning line of the (k-1)n+1th row is smaller than the thickness of the RGB color layer of other rows, k≥2, n≥1. Through the above methods, the present invention can avoid dark lines and improve display quality.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to a touch liquid crystal display panel, a CF substrate and a touch display device. Background technique [0002] With the increasingly fierce competition in the smart phone market, the structural design of small and medium-sized electronic products such as mobile phones has become one of the focuses of current mobile phone manufacturers, and an important solution to realize the thinner and lighter display screens of mobile phones is It is to use the In-Cell TP LCD structure to replace the original external TP LCD structure. [0003] Small and medium-sized LTPS (Low Temperature Polysilicon) LCDs with In-Cell architecture mostly use time-sharing drive scanning methods for display and touch (such as figure 1 Shown): That is, every time the gate line (gate) scans N lines, it stops to perform a part of the touch detection scan, and then the gate line scans N lines again, ...
