[0028] 1. The first embodiment

[0029] 1. Structure

[0030] figure 1 A schematic structure of the display 1 of the embodiment of the present invention is shown. The display 1 includes a display panel 10 and a peripheral circuit 20 for driving the display panel 10 .

[0031] display panel 10

[0032] The display panel 10 includes a plurality of scan lines WSL extending in the row direction, a plurality of data lines DTL extending in the column direction, and a plurality of data lines respectively arranged at positions corresponding to intersections of the scan lines WSL and the data lines DTL. Pixel 11. The pixels 11 in the display panel 10 are two-dimensionally arranged in the row direction and the column direction over the entire pixel region 10A of the display panel 10 . Each pixel 11 corresponds to a dot which is the smallest unit constituting a screen on the display panel 10 . When the...

Abstract

There is provided a driving circuit driving pixels in a display, the pixels each including a liquid crystal cell and a memory. The driving circuit includes: a dividing section dividing one frame period into subfields, the subfields corresponding to respective bits of gray-scale data and having period lengths commensurate with weights of the corresponding bits; a correction section correcting, when bit sequences of two sets of gray-scale data corresponding to two pixels adjacent to each other differ from each other, gray-scale data having a higher gray-scale level out of the two set of gray-scale data, to further increase the gray-scale level thereof; and an ON-OFF period control section controlling a ratio of an ON period or an OFF period to one frame period by bringing the liquid crystal cell of the pixel into an on state or an off state according to a corresponding bit in each of the subfields.

Description

[0001] Cross References to Related Applications [0002] This application contains subject matter related to that disclosed in Japanese Priority Patent Application JP2011-189926 filed in Japan Patent Office on Aug. 31, 2011, the entire content of which is hereby incorporated by reference. technical field [0003] The present invention relates to a driving circuit for performing gray-scale display (gray-scale display) through pulse-width modulation (Pulse-width modulation; PWM) and a display including the driving circuit. In addition, the present invention also relates to a method for driving the above display. Background technique [0004] In a digital display that performs grayscale display by PWM, in a typical case of 5 bits (32 grayscales) such as Figure 8 The grayscale display method shown in . Specifically, as Figure 8 As shown in , for example, with one bit (1bit) data of several ms width as a unit, five pieces of data with a period length ratio of 1:2:4:8:16 are pr...
