Liquid crystal display and method of manufacturing the same
First Claim
1. A liquid crystal display comprising:
- a liquid crystal display panel having a two substrates provided opposite to each other and a liquid crystal sealed between the two substrates; and
a light source device having a planar light guide plate for guiding light incident thereupon and a plurality of linear light sources that are provided at an edge of the planer light guide plate and that are turned on for a predetermined turn-on time within a frame period at predetermined blinking frequency and at different timing.

Abstract
There is provided a liquid crystal display having good display characteristics and a method of driving the same. Pixel data is written in plural pixels on one gate bus line at a top end of a display area at a first point in time on a line sequential basis. At a second point in time, the writing of pixel data in pixels in an upper part of the screen is completed, and writing of pixel data in pixels in a lower part of the screen is started. At a third point in time, the writing of pixel data in the pixels in the lower part of the screen is completed. A fluorescent tube on the upper side of the screen is turned on for a period between a third point in time after the writing of pixel data in the upper part of the screen and a fourth point in time before writing of pixel data for the next frame is started and is turned off in other periods. A fluorescent tube on the lower side of the screen is turned on for a period between a fifth point in time after the writing of pixel data in the lower part of the screen in the preceding frame and a sixth point in time before writing of pixel data in the lower part of the screen is started and is turned off in other periods.

15. A method of driving a liquid crystal display, comprising the steps of:
-
calculating luminance data for each pixel based on the tone of the pixel in a predetermined period;
calculating a duty ratio that is the ratio of a turn-on time to the predetermined period based on at least any of a maximum value, a minimum value, and an average value of the luminance data; and
blinking a planar light source based on the duty ratio. - View Dependent Claims (16, 17, 18, 19)
