Patent ID: 7616182

Claim:
A display device comprising: M rows and N columns (M and N are natural numbers respectively) of pixels; M gate lines; N source lines; a circuit for storing a data signal of an (m−1)-th row (2≦m≦M, m is a natural number); N circuits, wherein an n-th circuit (1≦n≦N, n is a natural number) of the N circuits is configured to compare a data signal of an m-th row with the data signal of the (m−1)-th row before the data signal of the m-th row is input to an n-th source line of the N source lines; N first switches electrically connected to each other and electrically connected to a power source circuit, wherein an n-th first switch of the N first switches is electrically connected to the n-th source line; and N second switches electrically connected to each other, wherein an n-th second switch of the N second switches is electrically connected to the n-th source line.
