Member 210 and a plurality of touch line 220.Wherein, pixel unit makes this aobvious under the cooperation of data line, scan line and driving chip 230
Show that substrate 200 has display function, touch unit 210 makes the display base plate in the case where touching the cooperation of line 220 and driving chip 230
200 have touch function.
In the present embodiment, multiple data lines and multi-strip scanning line intersect to form multiple pixel regions, multiple pixel regions
Form viewing area.It is provided with above-mentioned pixel unit, touch unit 210 in the viewing area and touches line 220.Wherein, multiple pictures
Plain unit and multiple touch units 210 are arranged in viewing area in a manner of array arrangement.
In above-mentioned multiple touch units 210, at least one described touch unit 210 and at least two 220 electricity of touch line
Property connection.The driving chip 230 includes multiple pins, and it is logical to touch the touch unit 210 that line 220 is electrically connected at least two
It crosses this at least two touch lines 220 to be electrically connected at least two pins of the driving chip 230 respectively, at least two pin
In, the first end of each pin is electrically connected by corresponding touch line 220 with the touch unit 210, one of pin
Second end and the second end of other pins are electrically connected.As a result, at least one touch unit 210 by a plurality of touchs line 220 and
Driving chip 230 is electrically connected, and is equivalent to a plurality of 220 parallel connection of touch line, is reduced the load of the touch unit 210, in turn
The signal transmission delay between the touch unit 210 and driving chip 230 is shortened, while not influencing the display base plate 200
Pixel transmitance.
In the prior art, only have partial touch line in a plurality of touch line and touch unit is electrically connected, remaining touch line
It is then hanging to be not used.And in the present embodiment, it is electrically connected by making remaining touch line 220 and touch unit 210, then should
