Embodiment Construction

[0020] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0021] As mentioned in the background technology, in the existing AMOLED panels, the light-emitting devices in the always-on display area are in the working state for a long time, resulting in a rapid decline in life, so when the full-screen image is displayed, the brightness of the image in the always-on display area is lower than that of the co...

Abstract

The invention provides a driving method and driving device of an AMOLED (Active Matrix Organic Light Emitting Diode) display device, relates to the technical field of display and is used for solving the problem of poor display since the decay of the service life of a light emitting device of a normally-on display region is faster than that of the other display regions. The driving method comprisesthe following steps of according to a display image signal, performing analysis to obtain coordinates of all pixels in the normally-on display region; dividing all pixels of the normally-on display region into N groups, wherein the N is greater than or equal to 2; when the normally-on display region needs to perform normally-on display, sequentially driving N groups of pixels in the normally-on display region according to the pixels coordinate obtained through analysis; periodically performing driving by using the period as one driving period, wherein the driving period is smaller than or equal to the maximum unit time of the response of human eyes on the brightness information. The driving method is applied to the AMOLED image display driving process.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a driving method and a driving device of an AMOLED display device, and an AMOLED display device. Background technique [0002] Compared with traditional LCD panels, AMOLED (Active Matrix Organic Light Emitting Diode, Active Matrix Organic Light Emitting Diode) panels have the characteristics of faster response, higher contrast, and wider viewing angles, so AMOLED panel industry has attracted widespread attention. As a new generation of display devices, AMOLED panels must meet various display requirements within their working life, and the overall picture quality must meet user needs. [0003] According to the application requirements of display devices, terminal manufacturers now require that some display areas of AMOLED panels be always on during the display process, and the display content is fixed, such as displaying brand logo (logo), time, notification reminders and...
