Problems solved by technology

[0006] However, if Figure 4 As shown, since a single frame is displayed in the manner of simultaneously displaying two sub-frames, one bright and one dark, the naked eye will easily perceive the difference in brightness of the picture, which means the so-called flicker phenomenon (Flicker)
In this way, although the smear phenomenon is eliminated, the quality of the display image will still be reduced due to the introduction of flicker
Furthermore, the average brightness of a single frame displayed is also reduced due to the insertion of black subframes

[0021] see Figure 5 with Image 6 . Figure 5 It is a schematic diagram of outputting frames F(n) and F(n+1) respectively divided into two groups of subframes Fn_1, Fn_2 and Fn+1_1, Fn+1_2 in the present invention. Image 6 It is a schematic diagram of cutting the gamma curve f(g) representing the average brightness into a first gamma curve f1(g) and a second gamma curve f2(g) according to a predetermined grayscale value x in the present invention. in, Figure 5 The shown frames F(n) and F(n+1) use the gamma curve f(g) as the basis for their display brightness, Figure 5 The sub-frames Fn_1 and Fn+1_1 shown use the gamma curve f1(g) as the basis for their display brightness, and Figure 5 The sub-frames Fn_2 and Fn+1_2 shown use the gamma curve f2(g) as the basis for their display brightness. Please note that the gamma curve is a function of the relationship between the brightness and the grayscale value used by a display pixel, that is, a motion picture response functio...

Abstract

The invention relates to a method for relieving image smearing and image track phenomena, which comprises: when a plurality of frames are displayed on the screen, cutting each gamma curve which controls the brightness of the frames into two gamma curves according to a preset grey-scale value for displaying two corresponding sub-frames which are different in brightness; and correcting the grey-scale value curves of a single frame and a frame received previously for eliminating the image smearing and image track phenomena at the same time when two frames with a large grey-scale value differenceare output continuously. The invention also provides a displayer for relieving the image smearing and image track phenomena.

Description

technical field [0001] The invention relates to a method for improving the smear phenomenon and tracking phenomenon of a display and a related display. Background technique [0002] Common display panels include liquid crystal panels and organic light emitting diode (Organic Light Emitting Diode, OLED) panels, and when the dynamic image quality of the liquid crystal display panel is poor, the main reason is insufficient response speed. However, in fact, the steady-state (Hold-type) driving method used by the general display panel will also produce a motion blur phenomenon, which will reduce the dynamic image quality of the display panel. see figure 1 , which is a graph showing the relationship between time and luminance when a general display panel operates using a steady-state driving method. The solid line is the curve when the general display panel emits light in a steady state, and the dotted line represents the display displayed by the human naked eye in a steady state...
