Liquid crystal display device and method for driving the same |
摘要 |
To increase the frequency of input of image signals in terms of design in a field-sequential liquid crystal display device. Image signals are concurrently supplied to pixels provided in a plurality of rows among pixels arranged in matrix in a pixel portion of the liquid crystal display device. Thus, the frequency of input of an image signal to each pixel can be increased without change in response speed of a transistor or the like included in the liquid crystal display device. |

1. A driving method of a liquid crystal display device in which each of a plurality of pixels comprises a first transistor, a second transistor, a third transistor, and a liquid crystal element, the driving method comprising the steps of:
turning on the first transistor in each of the plurality of pixels in first to n-th rows so that a first image signal is input to the liquid crystal element through the first transistor by sequentially inputting a first selection signal to a first scan line to an n-th scan line in a period, turning on the second transistor in each of the plurality of pixels in (n+1)th to 2n-th rows so that a second image signal is input to the liquid crystal element through the second transistor by sequentially inputting a second selection signal to a (n+1)th scan line to a 2n-th scan line in a period, turning on the third transistor in each of the plurality of pixels in (2n+1)th to 3n-th rows so that a third image signal is input to the liquid crystal element through the first transistor by sequentially inputting a third selection signal to a (2n+1)th scan line to a 3n-th scan line in a period, after finishing inputting the first to third selection signals respectively from the k-th scan line, from the (n+k)th scan line and from the (2n+k)th scan line, emitting light from a light source for the first to k-th rows, a light source for the (n+1)th to (n+k)th rows and a light source for the (2n+1)th to (2n+k)th rows, wherein n is a natural number of 3 or more, wherein k is a natural number of 2 or more and less than n, and wherein a color of the light emitted from the light source for the first to k-th rows, a color of the light emitted from the light source for the (n+1)th to (n+k)th rows, and a color of the light emitted from the light source for the (2n+1)th to (2n+k)th rows are different from one another. |
