Abstract
In a liquid crystal display device where each unit pixel p arranged on a liquid crystal panel 101A is constituted by a plurality of pixels p1, p2, and p3, the pixels p1, p2, and p3 are divided into sub-pixels p11 and p12, sub-pixels p21, and p22, and sub-pixels p31 and p32, respectively. The liquid crystal display device is provided with driver ICs 201 and 202 for driving the sub-pixels p11, p21, and p31, and the sub-pixels p12, p22, and p32 constituting the pixels so that different gradation-brightness value characteristics may be given. Due to this, multi-gradation display can be performed.
Claims16
A liquid crystal display device comprising:
- a liquid crystal panel having substrates sandwiching a liquid crystal layer therebetween;
- a unit pixel disposed on one of said substrates, wherein the unit pixel includes:
- a plurality of sub-pixels;
- and
- a driving device configured to receive a gradation voltage setting input and produce an output voltage that drives each of said plurality of sub-pixels to include a different gradation-brightness value characteristic and the unit pixel to include a linear gradation-brightness value characteristic.
A liquid crystal display device comprising:
- a pair of substrates;
- a liquid crystal layer disposed between said pair of substrates;
- a plurality of gate lines disposed on one of said pair of substrates;
- a plurality of drain lines disposed on one of said pair of substrates and intersecting said plurality of gate lines;
- and
- a plurality of unit pixels disposed in a matrix shape defined by said plurality of gate lines and said plurality of drain lines;
- wherein said unit pixels include a plurality of sub-pixels;
- and
- wherein said driving device includes a plurality of drivers configured to receive a gradation voltage setting input and produce an output voltage that drives each of said plurality of sub-pixels connected to a same one of the plurality of gate lines and different, adjacent drain lines to include a different gradation-brightness value characteristic, and the plurality of unit pixels to include a linear gradation-brightness value characteristic.
