Problems solved by technology

[0007] Since the cut-off time of the light-emitting signal in the second control signal is greater than the cut-off time of the light-emitting signal in the first control signal, the light-emitting time of the pixel driving circuit is shortened at low frequencies, which solves the flickering problem in the prior art when switching frequencies

Abstract

The invention provides a frequency conversion refreshing method, a pixel driving method, a frequency conversion refreshing device and electronic equipment. The frequency conversion refreshing method comprises the following steps of: when a picture refreshing frequency is changed from a first frequency to a second frequency, switching a control signal input into the pixel driving circuit from a first control signal corresponding to the first frequency to a second control signal corresponding to the second frequency; and enabling the pixel driving circuit to control a light emitting element to emit light according to the second control signal, wherein the first frequency is greater than the second frequency, the cut-off time of a light-emitting signal in the second control signal is longer than the cut-off time of a light-emitting signal in the first control signal, and a storage capacitor in the input pixel driving circuit is matched with the first frequency. Since the cut-off time of the light-emitting signal in the second control signal is longer than that of the light-emitting signal in the first control signal, the light-emitting time of the pixel driving circuit at a low frequency is shortened, and the splash screen problem during frequency switching in the prior art is solved.

Description

technical field [0001] The present invention relates to the technical field of OLED display, in particular to a frequency conversion refresh method, a pixel driving method, a device and electronic equipment. Background technique [0002] An organic light emitting diode (OLED Lighting Emitting Diode, OLED) display device has many advantages such as self-illumination, low driving voltage, high luminous efficiency, short response time, and wide temperature range. It is recognized as the display device with the most development potential. OLEDs are classified into passive organic electroluminescent diodes (Passive matrix OLED, PMOLED for short) and active matrix organic light emitting diodes (Active Matrix OLED, AMOLED for short) according to driving methods. The AMOLED display device has a plurality of pixels arranged in an array, and each pixel is driven to emit light by a pixel driving circuit. For dynamic pictures, the display quality can be improved by increasing the pict...
