Exhibition, comprehensive screen technology is even more industry mainstream among these.Comprehensive screen technology can not only increase the effective area of mobile phone, but also be promoted
The face value of mobile phone, allows mobile phone to seem more there is technology sense, and in addition the positive area of same fuselage can accommodate bigger screen,
Visual experience is obviously improved.In order to meet the diversified demand of people, shown using the touch-control of comprehensive screen technology
Panel usually requires to cut edge, and such as earpiece, camera, face can be embedded in by, which digging out in touch-control display panel, knows
The notch section of the functional modules such as individual sensor.
Existing touch-control display panel generally includes two kinds of touch control electrode arranged in a crossed manner, as shown in Figure 1, wherein
Multiple touch control electrodes 11 of one type successively arrange in the horizontal direction and form horizontal touch channel, referred to herein as the first touching
Electrode 11 is controlled, multiple touch control electrodes 12 of another type successively arrange along the vertical direction and form vertical touch-control channel, here
Referred to as second touch control electrode 12.Hereafter be touch-driven electrode with the first touch control electrode 11, second touch control electrode 12 is touch-control
For induction electrode, certain first touch control electrode 11 or touch-control sensing electrode, second touch control electrode 12 are touch-control driving
Electrode.It will form mutual capacitance, finger etc. at the crossover location of the first touch-driven electrode 11 and the second touch-control sensing electrode 12
The external capacitive that contact is formed will change the mutual capacitance, to can be detected out the specific location of touch point.
When the touch-control display panel is dug out the notch section 13 for being embedded in the functional modules such as earpiece, camera, lead to
It often will lead to the partial electrode missing of the first touch control electrode 11 and/or second touch control electrode 12 here, such as shown in Fig. 1, edge
The partial electrode for the first touch control electrode 11 that horizontal direction is successively arranged lacks, i.e. the partial electrode missing of horizontal touch electrode,
The touch-control channel of horizontal direction is caused to disconnect, the resistance value that undoubtedly will lead to first touch control electrode 11 at this time increases.And first
The touching signals that the resistance value increase of touch control electrode 11 will lead to first touch control electrode 11 weaken, and then influence touch-control display surface
The touch-control sensitivity of plate.

This conduction to guarantee the touch-control channel of horizontal direction, as shown in Figure 1, the notch section 13 is provided with the first touch-control cabling
14, which is located at the non-display area of touch-control display panel and connect with the first touch control electrode 11.But in order to
The narrow frame of screen technology comprehensively and Rimless requirement are adapted to, the touch-control display panel is relatively narrow in the frame of notch section 13, also
It is to say, smaller in the cabling space that non-display area is reserved, this undoubtedly will lead to the first touch-control cabling 14 very carefully, still suffer from
Biggish resistance value so that the touching signals that still will lead to the first touch control electrode 11 weaken, and then influences touch-control display panel
Touch-control sensitivity.
