Background technology
Relative to touch panel being arranged on original method that liquid crystal panel uses, research integrated with liquid crystal panel for touch panel is had a lot.There is the in-cell touch-control display technique of a kind of touch-control structure in liquid crystal cell at present, its conventional means are, pixel cell arranges two plate electrodes, what this two plate electrodes therebetween was held is liquid crystal layer, when staff touch display, the electric capacity that its two plate electrode is formed changes, thus determines position of touch.But the touch LCD display panel with this spline structure is when making, described two plate electrodes technics comparing trouble is set.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of touch LCD display panel making touch-control in simple box.
For achieving the above object, the invention provides a kind of touch LCD display panel, comprise array base palte and color membrane substrates, described array base palte comprises several pixel cells that gate line and data line limit, be filled with chock insulator matter in described array base palte and described color membrane substrates, described chock insulator matter is with electric charge; Described array base palte is also provided with ordered series of numbers first conductor wire, number row second conductor wire, described array base palte is divided into several grid by described first conductor wire and described second conductor wire, described pixel cell is arranged in described grid, described first conductor wire one end is connected with first electric capacity one end, and the other end is connected to the first data acquisition chip; Described second conductor wire one end is connected with second electric capacity one end, and the other end is connected to the second data acquisition chip; Described chock insulator matter is positioned at the infall of described grid, is connected respectively with described first conductor wire and the second conductor wire.
The described first electric capacity other end is connected to a constant voltage chip, and the other end of described second electric capacity is connected to a constant voltage chip.
Described chock insulator matter is tin indium oxide ITO at the junction material with described first conductor wire and the second conductor wire.
When staff is when touching touch LCD display panel of the present invention, CHARGE DISTRIBUTION on chock insulator matter changes, thus voltage fluctuation is produced on connected first conductor wire and the second conductor wire, described first data acquisition chip and the second data acquisition chip gather voltage signal, determine the position of touch-control according to the place on line of the voltage signal received.
Beneficial effect of the present invention:
1, described first conductor wire and described second conductor wire can deposit when deposition of transparent conductive film ITO layer and be formed, and do not need other technique;
2, when touch cause the electric capacity of liquid crystal layer to change time, the change of CHARGE DISTRIBUTION on chock insulator matter, can coating-forming voltage signal, is passed to first and second data acquisition chip, thus determines position of touch by first and second conductor wire;
3, when touch-control causes liquid crystal layer electric capacity to change, its image quality will be affected, such as occur the distortion of color, the charge variation on described chock insulator matter can produce the electric field that is suppressed above-mentioned liquid crystal layer capacitance variations, thus can reduce the situation probability of happening of image quality distortion.
