Abstract

The embodiment of the invention provides a signal output circuit, a driving IC, a display device and a driving method thereof, relates to the technical field of display, and can improve the display effect. The signal output circuit comprises a receiving unit and an initial signal output unit; the receiving unit is configured to receive an indication signal indicating an image refresh frequency, wherein the refresh frequency is one of at least two set refresh frequencies; the initial signal output unit is configured to output initial signals in one-to-one correspondence with the refresh frequencies for different refresh frequencies according to the indication signal, wherein the initial signals comprise a pulse in each repetition duration, and the repetition durations of the different initial signals are the same; for different starting signals, the duty ratios of other pulses except the first pulse in each frame of time are the same fixed value; the refresh frequency of the first pulsein each frame of time is inversely proportional to the duty ratio under the condition that the low level is effective, and the refresh frequency is directly proportional to the duty ratio under the condition that the high level is effective.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a signal output circuit, a driving IC, a display device and a driving method thereof. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) display device has thin, light, wide viewing angle, active light emission, continuously adjustable light color, low cost, fast response speed, low energy consumption, low driving voltage, low operating temperature With the advantages of wide range, simple production process, and high luminous efficiency, it is widely used in various terminal display products with high-resolution color screens. [0003] When the terminal display product is running a special application, such as when a mobile phone is running a game, it has higher requirements on the clarity and fluency of the image, requires a higher refresh rate, but also has the problem of high power consumption. When terminal display products are ...
