Abstract

The invention provides a display device which comprises a display panel and a driving control circuit. The display panel includes a plurality of pixels. The driving control circuit is coupled to the display panel. In the first mode, the drive control circuit drives a plurality of pixels separately in a first frame period. In the second mode, the drive control circuit drives the first part of pixels in the plurality of pixels separately in a second frame period. The first frame period is greater than the second frame period. The number of pixels of the first portion is less than the number of pixels of the display panel. In the second mode, the plurality of pixels are divided into a plurality of first blocks, and the pixels of the first part comprise at least one pixel in each first block.

Description

technical field

[0001] The present invention relates to a display device, especially a display device capable of adjusting frame rate. Background technique

[0002] As users use the display panel in more and more diverse situations, users have more and more flexibility in choosing the resolution and frame rate of the display panel. Generally speaking, however, the pixel clock frequency of the display panel is fixed, so the frame rate of the display panel is also limited and difficult to increase. In addition, as the resolution of the display panel is getting higher and higher, if the designer wants to increase the frame rate of the display panel, he needs to use a circuit with stronger functions and higher power consumption, resulting in an increase in cost, which cannot meet the needs of the user. the elastic demand of consumers. Contents of the invention

[0003] The purpose of the present invention is to provide a display device whose frame rate can be adjusted. [0...

Embodiment Construction

[0025] In order to have a further understanding of the purpose, structure, features and functions of the present invention, the detailed description is as follows in conjunction with the embodiments.

[0026] figure 1 is a schematic diagram of a display device 100 according to an embodiment of the present invention. The display device 100 includes a display panel 110 and a driving control circuit 120 . The display panel 110 may include a plurality of pixels P(1,1) to P(M,N). The driving control circuit 120 can be coupled to the display panel 110 .

[0027] In some embodiments, the pixels P(1,1) to P(M,N) may include a plurality of light emitting diodes (Light Emitting Diode, LED), a plurality of organic light emitting diodes (Organic Light Emitting Diode, OLED), a plurality of micro A light emitting diode (Micro Light Emitting Diode) or a plurality of sub-millimeter light emitting diodes (Mini Light Emitting Diode), and the drive control circuit 120 can individually drive t...
