Abstract:
A display apparatus for displaying an image by turning on pixels of a display section, comprising:an intermediate gradation processing circuit for ensuring pseudo-expression of an intermediate gradation by controlling a minimum gradation level of said display section; and a resolution limiting circuit for limiting display resolution information of a selected gradation level excluding said minimum gradation level, thereby shortening a time of selecting a pixel of said gradation level to be turned on, wherein said intermediate gradation processing circuit and said resolution limiting circuit convert data of a low order sub field, exclusive of a least significant sub field, in a manner to produce a specific sub field having identical data by processing a signal of plural lines and both of said circuits include a control-bit smoothing and error diffusion circuit which control said least significant sub field in dot-by-dot and forbid a carry to spread to a high order sub field,. whereby said pixels of said display section are driven based on outputs of said intermediate gradation processing circuit and said resolution limiting circuit.
