The hollow area 210 of touch-control display panel of the embodiment of the present invention 200 is located in a first touch control electrode unit 231.
A first touch control electrode unit 231 where hollow area 210 is incomplete first touching of local setting small area structure
Control electrode 240 and second touch control electrode 250.Knot is arranged in multiple touch control electrode units 230 except first touch control electrode unit 231
Complete first touch control electrode 240 of structure and second touch control electrode 250, and have normal touch-control performance.Where hollow area 210
A first touch control electrode unit 231 be minimum number, multiple touch control electrode lists except the first touch control electrode unit 231
Member 230 occupies maximum quantity, and the small area of the first touch control electrode 240 contained by the former and second touch control electrode 250 is for the latter
The vast area of contained first touch control electrode 240 and second touch control electrode 250 can be ignored.200 base of touch-control display panel
Touch-control is realized using the touch control electrode unit 230 except the first touch control electrode unit 231 in sheet.First touch control electrode unit 231
Except touch control electrode unit 230 have normal touch-control performance, the touch-control performance of touch-control display panel 200 is substantially uniform.
Fig. 5 is the floor map of another embodiment of the present invention touch-control display panel 200.
As shown in figure 5, the size of hollow area 210 is greater than the side length of the first touch control electrode unit 231；Hollow area 210 is from
One touch control electrode unit 231 extends to second touch control electrode unit 232；Hollow area 210 is in single second touch control electrode unit 232
In occupy the first area, the area ratio of the first area and single second touch control electrode unit 232 is less than 2%.
The hollow area 210 of another embodiment of the present invention touch-control display panel 200 is extended to from the first touch control electrode unit 231
Second touch control electrode unit 232, hollow area 210 occupy the first area, the first area in single second touch control electrode unit 232
Area ratio with single second touch control electrode unit 232 is less than 2%.Hollow area 210 is in single second touch control electrode unit 232
In the first area for occupying the area of single second touch control electrode unit 232 can be ignored.Exclude the first area
Approximate first touch control electrode 240 and second touch control electrode 250 with structural integrity of second touch control electrode unit 232, approximation tool
There is normal touch-control performance.Therefore, hollow area 210 occupies the first area substantially not shadow in second touch control electrode unit 232
Ring the touch-control performance of touch-control display panel 200.In addition, hollow area 210 extends to the second touch-control from the first touch control electrode unit 231
Electrode unit 232 rather than only be set in the first touch control electrode unit 231, can expand area therein and accommodate it is bigger
Camera or sensor.
As shown in figure 4, touch control electrode unit 230 includes two adjacent third touch control electrode units 233, hollow area 210
Center be located at the boundary line midpoints of two adjacent third touch control electrode units 233；Touch control electrode unit 230 further includes multiple
Four touch control electrode units 234, the 4th touch control electrode unit 234 is close to third touch control electrode unit 233.
In another embodiment of the present invention touch-control display panel 200, hollow area 210 is centrally disposed in two adjacent thirds
The boundary line midpoint of touch control electrode unit 233, rather than it is set to the other positions such as the corner of third touch control electrode unit 233.In
The boundary line midpoint for being centrally disposed in two adjacent third touch control electrode units 233 of dead zone 210, the outside of hollow area 210 is still
It can entirely fall in two adjacent third touch control electrode units 233, entire hollow area 210 can be set in two adjacent third touchings
It controls in electrode unit 233.The other positions such as the corner for being centrally disposed in third touch control electrode unit 233 of hollow area 210, it is hollow
Necessarily some falls into the 4th touch control electrode unit 234 of surrounding outside area 210, and entire hollow area 210 is not settable
In in two adjacent third touch control electrode units 233.Therefore, hollow area 210 is centrally disposed in two adjacent third touch-controls electricity
The boundary line midpoint of pole unit 233 helps entire hollow area 210 and is set in two adjacent third touch control electrode units 233.This
