The impact on stray capacitance that causes in order to reduce the liquid crystal molecule upset, the inventor is by repeatedly adopting 2D simulation softward (Dimos optical simulation software) to seek solution.Its model of setting up of simulation as shown in Figure 5, it comprises touch structure 221 and liquid crystal display structure between the first substrate 100 that is oppositely arranged and second substrate 200, and touches the organic dielectric layer 227 between structure 221 and the liquid crystal display structure.Wherein, the touch structure 221 of skim signal comprises the touch structure of the protective seam 210 that is positioned among Fig. 1 on the second substrate 200, metal level 220, indium tin metal oxide skin(coating) 230, organic film 240, metal bridge layer 250 among Fig. 5, and the organic dielectric layer 227 of skim signal comprises second medium layer 260 and the planarization layer 270 among Fig. 1 among Fig. 5.Wherein, protective seam is black-matrix layer; be used for blocking the parts such as metal level, TFT, cabling, reach the purpose that prevents light leak, the second medium layer is color film; planarization layer is organic film; also have the both alignment layers (not shown) between planarization layer and the liquid crystal layer, the material of both alignment layers is the polyester type organic, and specific inductive capacity is 3.5; the polyamides ethamine that concrete available liquid crystal manufacturing field is commonly used, specific inductive capacity is 3.5.Also comprise liquid crystal layer 150 among Fig. 5.Liquid crystal layer is for 150 times public electrode 140, and public electrode 140 following first medium layers 130 for insulation are pixel electrode layer 120 below first medium layer 130, then are second medium layer 110.Described first medium layer 130 and second medium layer 110 are the insulation organic film.In this model, distance touch structure 221 nearer be public electrode 140, the stray capacitance that namely needs to measure is the capacitor C between touch structure 221 and the public electrode 140.The inventor carries out analog simulation by the structure to above-mentioned embedded touch display device, finds that the live width ratio of public electrode has key influencing factor, and in the scope of some live width ratio, the upset of liquid crystal molecule has less impact for the impact of electric capacity.Design parameter arranges as follows:
Because the variation of stray capacitance Ct, Cr all is consistent under same driving voltage, then is referred to as C, the variable quantity under certain driving voltage is △ C.The voltage of public electrode is set as 0v, pixel electrode voltage selects black attitude voltage and white attitude voltage to simulate, wherein, black attitude voltage is low-voltage, get 0.1v, white attitude voltage is high voltage, because maximum brightness voltage (white attitude voltage) is slightly inconsistent under the design of different public electrodes, generally speaking between 4.5-5.5v.The gross thickness of organic dielectric layer 227 is a value less than or equal to 11 μ m, and liquid crystal layer 150 thickness are set to 3.5 μ m.Recently carry out repeatedly simulation in the capacitance variations of different distance according to the live width of different public electrodes, the summation pitch(=W+L of the width W of each public electrode and spacing L wherein) size is from 6um to 9um, simulation has obtained a series of W/L(live width ratios) penetrance T and the situation of change of △ C, and obtained the relation curve of W/L and penetrance T and △ C, as shown in Figure 6 and Figure 7.Wherein Fig. 6 be live width than the size of W/L and the relation of penetrance T, horizontal ordinate is that live width is big or small than W/L, ordinate is penetrance T; Fig. 7 be live width than the size of W/L and the relation of rate of change of capacitance △ C, horizontal ordinate is that live width is big or small than W/L, ordinate is rate of change of capacitance △ C.
For the penetrance of liquid crystal layer, require it greater than 151, as can be seen from Fig. 6, its ratio that needs live width and line-spacing is less than 2.5; For rate of change of capacitance, require it less than 1.51, as can be seen from Fig. 7, the ratio of live width and line-spacing have to be less than 0.5.Comprehensive above two conclusions, the ratio of live width and line-spacing is between 0.5 to 2.5.
