Abstract

A liquid crystal panel ( 2 ) includes scanning signal lines ( 31 ) for supplying scanning signals to gate electrodes ( 20 ) of TFTs ( 14 ), and data signal lines ( 32 ) for supplying data signals to data electrodes ( 24 ) of TFTs. The liquid crystal panel further includes auxiliary capacitive electrode pads ( 27 a) for use in forming auxiliary capacitance and an auxiliary capacitive lines ( 33 ) so as not to generate a capacitive bond with the scanning signal lines. The liquid crystal panel is driven at a rewriting frequency of a screen of not more than 30 Hz. As a result, the liquid crystal panel can be driven at a low consumption power while maintaining a desirable display quality of the liquid crystal panel.

Description

[0001] This application is a divisional application of the invention patent application filed by the applicant on April 24, 2001 with the application number "01812023.7" and the invention title "display device, display device driving method and electronic equipment equipped with display device" . Technical field [0002] The present invention relates to low power consumption of display devices. Background technique [0003] In recent years, the application of liquid crystal display devices in word processors, laptop personal computers, pocket TVs, etc. has been rapidly developed. Especially in the liquid crystal display device, the reflective liquid crystal display device that performs display by reflecting external incident light does not require a backlight, consumes less power, is thin, and can be reduced in weight, which is eye-catching. [0004] Existing reflective liquid crystal display devices can be roughly divided into: pen-segment display methods that can only display si...

Problems solved by technology

Therefore, there is a disadvantage of increasing the cost due to the increase in the size of the peripheral circuit

[0023] In the method disclosed in Japanese Patent Application Laid-Open No. 6-342148, since the ferroelectric liquid crystal is basically a value (black and white) display, color tone display cannot be performed, and natural images cannot be displayed. Requires advanced plate making technology, so it is difficult to realize, and has not been put into practical use so far

[0024] In this way, the existing driving methods for matrix liquid crystal display devices cannot easily achieve sub-low power consumption while satisfying basic display qualities such as brightness, contrast, response speed, and gray scale.

Moreover, the above-mentioned existing matrix-type liquid crystal display device activation method cannot take into account sufficient low power consumption and flicker-free high display quality.
