Embodiment Construction

[0012] A number of implementations of the present invention will be disclosed below with the accompanying drawings. For the sake of clarity, many practical details will be described together in the following description. It should be understood, however, that these practical details should not be used to limit the invention. That is, in some embodiments of the present invention, these practical details are unnecessary. In addition, for the sake of simplifying the drawings, some well-known and commonly used structures and elements will be shown in a simple and schematic manner in the drawings.

[0013] Herein, when an element is referred to as "connected" or "coupled", it may mean "electrically connected" or "electrically coupled". "Connected" or "coupled" may also be used to mean that two or more elements operate or interact with each other. In addition, although terms such as "first", "second", etc. are used herein to describe different elements, these terms are only used t...

Abstract

A display device and a drive method thereof are disclosed. The display device includes a display, a driver, a memory, and a controller. The display includes a display panel and a backlight unit with aplurality of light-emitting elements to display an image. The driver is electrically connected to the display to transmit a backlight control signal to the backlight unit. The memory stores a plurality of adjustment instructions, and each adjustment instruction includes a drive frequency and a control parameter. The controller is electrically connected to the display, the driver, and the memory.The controller is configured to determine a drive frequency and a control parameter corresponding to the drive frequency in the memory according to a frequency adjustment signal, and then adjust the backlight control signal according to the control parameter, to change a duty cycle of the backlight control signal, so that a refresh rate of the backlight unit meets a requirement of a user.

Description

technical field [0001] The invention relates to a display device and a driving method thereof. Background technique [0002] Liquid Crystal Displays (LCDs) are widely used in various consumer electronic products and become the mainstream of displays due to their advantages of high image quality, small size, light weight, low driving voltage and low power consumption. [0003] Since the liquid crystal is a non-spontaneous optically active element, the liquid crystal display needs to provide light through the backlight unit, and change the twist angle of the liquid crystal by controlling the voltage to adjust the passing rate of the light to form a display screen. Therefore, the backlight unit The driving method has a significant impact on the display quality of the liquid crystal display. [0004] In all kinds of display devices nowadays, the refresh rate of the backlight unit is fixed, and the user cannot adjust it arbitrarily. For example, animation designers cannot easily...
