Title:
液晶表示装置の駆動方法及び駆動装置
Document Type and Number:
Japanese Patent JP4272595
Kind Code:
B2
Abstract:
A driving method and apparatus for a liquid crystal display are disclosed that stabilizes the variation of the brightness of a back light in correspondence with data to be displayed. In the method, the data is converted into brightness components. The brightness components are divided into a plurality of brightness areas. The brightness components are arranged into a histogram for each frame and thereafter a control value of a most-frequent value or average value of the histogram is extracted. The extracted control value is stored along with other control values including the extracted control value of a frame prior to the control value of the current frame by at least two frames. The brightness of the back light is controlled using the extracted control value of the current frame and one or more of the other stored control values.
