Abstract:
1. A display device comprising: a display panel having: a first dummy shift register set; a second dummy shift register set; a third dummy shift register sets; a fourth dummy shift register set, wherein each dummy shift register sets includes m dummy shift registers; a first bi-directional shift register set coupled between the first dummy shift register set and the second dummy shift register set and including L bi-directional shift registers configured to drive the M main gate lines, wherein a first bi-directional shift register in the first bi-directional shift register set is coupled to the first dummy shift register set, an L a second bi-directional shift register set coupled between the third dummy shift register set and the fourth dummy shift register set and including L bi-directional shift registers configured to drive the M sub gate lines, wherein a first bi-directional shift register in the second bi-directional shift register set is coupled to the third dummy shift register set, an L a first directional start pulse signal generator coupled to the first bi-directional shift register in the first bi-directional shift register set and configured to enable a (1+m)th main gate line by outputting a first start pulse signal, and coupled to the (1+m−c)th dummy shift register in the third dummy shift register set and configured to enable (1+m−c)th sub gate line by outputting the first start pulse signal.
