In the present embodiment, this assorted news shielding layer 11 can be made up of electrically conducting transparent materials such as tin indium oxides (ITO). The mode ground connection that this assorted news shielding layer 11 is overlapped by the framework (Frame) of the mode and touch control display apparatus 100 of pasting conductive material (such as conductive aluminum foil etc.), it is possible to by putting elargol between the TFT on colored filter 22 and TFT substrate or paste the mode ground connection of small pieces conductive material. It is understood that in other embodiments, this assorted news shielding layer 11 is also by other feasible mode ground connection in institute.
As shown in Figure 2, this touch control display apparatus 100 also comprises at least two conduction bands, such as the first conduction bands 30 and the 2nd conduction bands 31. These at least two conduction bands are arranged on display panels 20 and are connected with described assorted news shielding layer 11 respectively in different positions place, and every bar conduction bands comprise the protuberance outside protruding from this display panels 20 from this display panels 20 side, for measuring described assorted news shielding layer 11, whether ground connection is good. Preferably, every bar conduction bands are made by transparent conductive material, such as, be made up of the material identical with this assorted news shielding layer 11.
Preferably, as shown in Figure 2, these at least two conduction bands are arranged in the TFT substrate 24 of display panels 20, and the protuberance of every bar conduction bands is outstanding from the side of TFT substrate 24, and then outside protruding from whole display panels 20, to measure described assorted news shielding layer 11, whether ground connection is good.
In the present embodiment, only comprise the first conduction bands 30 for touch control display apparatus 100 and the 2nd conduction bands 31 are described.
As shown in Figure 2, these first conduction bands 30 and the 2nd conduction bands 31 lay respectively at the different sides of TFT substrate 24, such as, lay respectively at the side (source side) of side (gate side) and the input data signal producing sweep signal for TFT substrate 24. These first conduction bands 30 and the 2nd conduction bands 31 are covered in the top of TFT substrate 24 and overlap by the modes such as an elargol or subsides conductive material and described assorted news shielding layer 11. These first conduction bands 30 comprise the first protuberance 301, and this first protuberance 301 protrudes from outside this TFT substrate 24 in the gate side of TFT substrate 24. 2nd conduction bands 31 comprise outside the 2nd protuberance the 311, two protuberance 311 protrudes from this TFT substrate 24 from another side that this TFT substrate 24 is relative with gate side.
