With reference to the sectional view that figure 2, Fig. 2 is the display panel 110 according to Fig. 1.As shown in Figure 2, display panel 110 also comprises liquid crystal layer 113, first substrate 114 and second substrate 115.Public electrode 111 is formed on first substrate 114, and pel array 112 is formed on second substrate 115.Liquid crystal layer 113 is arranged between public electrode 111 and pel array 112.Touch-control sensing module 120 is embedded between liquid crystal layer 113 and pel array 112.It is noted that the setting position of touch-control sensing module 120 in the present embodiment only exemplarily, the present embodiment is not as limit.Furthermore, touch-control sensing module 120 can be embedded in other position in display panel 110 according to the demand of reality, this part is described in embodiment afterwards.
As shown in Figure 1, driver module 130 is coupled to pel array 112 by sweep trace GL_1 ~ GL_n and data line DL_1 ~ DL_n, and is coupled to public electrode 111.Driver module 130, in order to provide common voltage signal to public electrode 111, makes public electrode 111 have a reference voltage level relative to pel array 112.In addition, driver module 130 also provides data voltage signal to pel array 112 by data line DL_1 ~ DL_n.
Specifically, pel array 112 comprises multiple pixel cell 200.Each pixel cell 200 is arranged at the confluce of sweep trace GL_1 ~ GL_n and data line DL_1 ~ DL_n.Each pixel cell 200 is in order to produce pixel value according to common voltage signal and corresponding data voltage signal.
It is the schematic diagram of a pixel cell 200 of pel array 112 according to Fig. 1 with reference to figure 3, Fig. 3.As shown in Figure 3, pixel cell 200 comprises pixel transistor 210, liquid crystal capacitance 220 and storage capacitors 230.The control end of pixel transistor 210 is coupled to sweep trace (such as: sweep trace GL_n-1), the first end of pixel transistor 210 is coupled to data line (such as: data line DL_n-1), and the second end of pixel transistor 210 is coupled to public electrode 111 by storage capacitors 230.In an operation, when pixel transistor 210 receives drive singal when opening by sweep trace GL_n-1, pixel transistor 210 receives data voltage signal by data line DL_n-1, and data voltage signal is stored in liquid crystal capacitance 220 and storage capacitors 230, to produce the pixel value of respective pixel unit 200.
In addition, touch-control sensing module 120 can comprise multiple first sensing electrode and multiple second sensing electrode (not being shown in figure).Each first sensing electrode arranges along first direction (such as: horizontal direction).Each second sensing electrode arranges along second direction (such as: vertical direction).Each first sensing electrode and the arrangement interlaced with each other of each second sensing electrode, and form sense capacitance in staggered place.By the change detecting sense capacitance, touch-control sensing module 120 has judged whether that touch-control occurs.
But when touch-control sensing module 120 is embedded in display panel 110, the element in display panel 110 with conductive material can form stray capacitance with the first sensing electrode in touch-control sensing module 120 and the second sensing electrode.For example, stray capacitance can be formed between the first sensing electrode in the public electrode 111 of display panel 110 and touch-control sensing module 120 and the second sensing electrode.In addition, also stray capacitance can be formed between the first sensing electrode in the metallic signal lines (such as: data line DL_1 ~ DL_n) of display panel 110 and touch-control sensing module 120 and the second sensing electrode.These stray capacitances can cause the discharge and recharge time (RC loading) of sense capacitance to increase, that is the sensitivity making touch-control sensing module 120 detect the change of sense capacitance declines.
Furthermore, when touch-control sensing module 120 is embedded in (as Fig. 2) in display panel 110, display panel 110 is in picture frame (frame) period, and some time is used to display frame, and remaining time is then used to detect touch-control.In order to avoid touch-control display panel 100 is when detecting, the sensitivity of its detecting of effect of parasitic capacitance that touch-control sensing module 120 produces because of public electrode 111 and data line DL_1 ~ DL_n, in the present embodiment, when touch-control display panel 100 carries out sensing touch-control by touch-control sensing module 120, driver module 130 is the state being in disconnection with the line of public electrode 111 and the line of driver module 130 and data line DL_1 ~ DL_n.
Furthermore, when touch-control sensing module 120 senses, the voltage quasi position of public electrode 111 and data line DL_1 ~ DL_n is positioned at suspension joint (floating) state.In other words, public electrode 111 and data line DL_1 ~ DL_n are in the state of open circuit.In the ordinary course of things, because public electrode 111 receives common voltage signal (as: ground voltage signal), therefore there is stray capacitance between public electrode 111 and touch-control sensing module 120.On the contrary, when the voltage quasi position of public electrode 111 and data line DL_1 ~ DL_n is positioned at floating, the stray capacitance that public electrode 111 and data line DL_1 ~ DL_n produce for touch-control sensing module 120 can reduce effectively, that is the stray capacitance between public electrode 111 and touch-control sensing module 120 just can reduce because of the voltage quasi position of public electrode 111 tool floating effectively, and then effectively improve the sensitivity that touch-control display panel 100 senses touch-control, that is reduce the discharge and recharge time of sense capacitance.
