Abstract

The present invention reduces moving image blurring in a hold-response-type display device. 1 frame is divided into 3 fields. Assuming the gradation-brightness characteristic of a first field as 1 g, the gradation-brightness characteristic of a second field as 2 g, and the gradation-brightness characteristic of a third field as 3 g, the third field is set at an initial stage or at a final stage of the frame. Due to such setting, the moving image blurring can be effectively reduced up to the relatively high brightness.

Description

technical field

[0001] The present invention relates to a hold-type display device such as a liquid crystal display device and an organic EL display, and particularly to a display device suitable for displaying moving images. Background technique

[0002] When classifying display devices particularly from the viewpoint of moving image display, they are roughly classified into impulse-response displays and hold-response displays. An impulse-response display is a type in which the luminance response decreases immediately after scanning, as in the light-emitting characteristics of a picture tube, and a hold-response display is a type that maintains the brightness based on display data until the next scan, like a liquid crystal display. .

[0003] As a feature of a display that remains responsive, good display quality without flicker can be obtained for still images, but there is a problem that the surroundings of moving objects appear blurred for moving images, that is, moving...
