Assignee: JAPAN DISPLAY INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 8:
9. The liquid crystal display device according to claim 8, wherein
the detection circuit calculates, when the first period is shorter than the second period, a liquid crystal capacitance value CgSre(r) of each of the pixels at the detection timing using Expression (3) and Expression (4)

CgSre(r)=(1−α)CgS-1(r)+αCgS(r)  (3)

α=PL(n)/PST(r)  (4)

where CgS-1(r) is a liquid crystal capacitance value corresponding to the gradation value of the pixel immediately before the selection timing, CgS(r) is a liquid crystal capacitance value corresponding to the gradation value of the pixel immediately after the selection timing, PL(n) is the first period, and PST(r) is the second period.
