Title: Liquid crystal display device and its driving method
Inventor: OCHI YUTAKA
IPC: G02F1/133
Filed: 2002-09-26
Abstract: <P>PROBLEM TO BE SOLVED: To solve the problems that rising interval to achieve a steady state condition having prescribed luminance is too long and brightness is not sufficient because pixels are driven in the order of the rows while intermittently controlling incident light beams to improve a blurred picture, in a conventional projection type liquid crystal display device.  <P>SOLUTION: When image signals indicated in (B) are applied to liquid crystals, a large effective voltage value is given to the liquid crystals because the pulse width is longer in the front half interval of one field, the rising speed becomes faster and brightness of the reflected light beams from liquid crystal display elements achieves a steady state condition in a relatively short period of time. In the back half interval of the one field, the pulse width is shorter, a small effective voltage value is given to the liquid crystals and the falling speed becomes faster. Thus, making the image signals to be the pulse width modulated signals as indicated in (B), timewise transition of the brightness of reflected light beams becomes closer to an impulse response. Moreover, improvement in the brightness and a blurred picture is attained by outputting driving pulses to pixels with a screen collective timing for every subframe.  <P>COPYRIGHT: (C)2004,JPO
