Claim Text:
1. A liquid crystal (LC) cell, comprising: a first LC cell and a second LC cell arranged opposite to the first LC cell, wherein the first LC cell is a normally white cell, and the second LC cell is a normally black cell; and wherein the LC cell comprises a plurality of pixels arranged in a matrix form, each of the pixels being configured with a first transistor and a second transistor, and each of the pixels is driven by two gate lines and two data lines, a first gate line turns on a gate of the first transistor and a first data line provides data voltage to the pixels by a source of the first transistor when the display brightness of the LC cell transforms from white to black, and a second gate line turns on a gate of the second transistor and a second data line provides the data voltage to the pixel by a source of the second transistor when the display brightness of the LC cell transforms from black to white; and wherein a time period for the diving voltage of the first LC cell is the same with that of the second LC cell, the driving voltage of the first LC cell remains at a high level for a first high time period and remains at a low level for a first low time period, the driving voltage of the second LC cell remains at the high level for a second high time period and remains at the low level for a second low time period, when the first high time period equals the first low time period, the second high time period equals to a sum of the second low time period and a response time for which the display brightness of the second LC cell transforms from white to black.
