Abstract
A display unit comprises a substrate, a plurality of first signal lines, a plurality of second signal lines and a plurality of first signal internal switching lines. The first and second lines are arranged in the display zone of the substrate in the manner of interlacement. The first signal internal switching lines are arranged in the display zone of the substrate, wherein each first signal internal switching line is electrically connected to a corresponding first signal line and arranged between the adjacent second signal lines. Each first signal internal switching line is intersected with a first signal line and has the same cross point with the first signal line. The invention causes all the signal lines to have the same loading effect by changing the configuration of signal lines or regulating the RC delay of partial signal lines, thus, the display unit will not have the bad effect on the display quality due to the non-uniform loading effect. The narrow-frame display unit can be achieved by setting the internal switching line by the display unit.
