Document Type and Number:
Japanese Patent JP4110772
Kind Code:
B2
Abstract:
A method of sub-field drive can display with a mode of placing emphasis on responsiveness and display with a mode of placing emphasis on gray-scale reproductiveness. A field is divided into plural sub-fields on a time axis, and each of such sub-fields is a control unit of driving a pixel. A code storing ROM stores a code that controls sub-fields to collecting on-voltage intensively in a former part of a field based on display data. Another code storing ROM stores a code that controls sub-fields to increase levels of gray scale based on display data. A data encoder determines whether each pixel of display data is an edge part of a moving image or not, selects a code that enables superior display in responsiveness at the edge part of a moving and selects a code that enables superior display in gray scale reproductiveness in other parts from the ROMs. Therefore, superior sight recognition of a moving image can be attained and reproduction of multi-levels gray scale in a still image can be available simultaneously.
