Title:
VIDEO SIGNAL LINE DRIVE CIRCUIT, DISPLAY DEVICE INCLUDING SAME, AND VIDEO SIGNAL LINE DRIVE METHOD
Document Type and Number:
WIPO Patent Application WO/2017/208954
Kind Code:
A1
Abstract:
Provided is a source driver (video signal line drive circuit) that uses a charge sharing system and achieves reduction in power consumption as compared to conventional technologies. In a short-circuiting circuit of the present invention, when it is assumed that consecutive source bus lines in a number of K (K is an even number not smaller than 4) are defined as one group and that numbers from 1 to K are assigned to the respective source bus lines in the number of K, the source bus lines are short-circuited such that, in each group, all pairs each composed of two source bus lines are equal in the sum of the numbers assigned to each of the pairs. For example, in the short-circuiting circuit, four consecutive source bus lines are defined as one group, and, in each group, the first source bus line and the fourth source bus line are short-circuited, and the second source bus line and the third source bus line are short-circuited.
