Abrégé
(EN) The invention discloses a display method of a display panel, the display panel and a display device. Aiming at received each frame of initial image data, the initial image data is converted to N frames of new image data according to a preset first mapping relation, wherein pixel points whose initial gray scale values are smaller than a preset value in the initial image data have a first gray scalevalue in K frames and have a second gray scale value in N-K frames among the generated N frames of new image data; the gray scale values of pixel points whose initial gray scale values are greater than or equal to the preset value in the initial image data are kept unchanged in the generated N frames of new image data; and displaying of each frame of new image data is performed at a preset refresh frequency. Therefore, more fine-sorted luminance levels are formed through combination by utilizing vision pause phenomenon of human eyes, so that luminance uniformity in images with comparatively low luminance is improved and true image information is restored accurately.
(ZH) 本发明公开了一种显示面板的显示方法、显示面板及显示装置,针对接收的每一帧初始图像数据,根据预先建立的第一映射关系将初始图像数据转换生成N帧新的图像数据;其中初始图像数据中初始灰阶值为小于预设值的像素点在生成的N帧新的图像数据中,有K帧为第一灰阶值,有N‑K帧为第二灰阶值;初始图像数据中初始灰阶值为大于或等于预设值的像素点,在生成的N帧新的图像数据中灰阶值保持不变;根据生成的每一帧新的图像数据以预设刷新频率进行显示。从而利用人眼的视觉暂停现象,组合出更为细分的亮度等级,进而可以在较低亮度画面下提高亮度均匀性,准确的还原真实画面信息。
