Embodiment 1

[0027] As mentioned in the background art, if the two operations of initializing and turning on the backlight are performed at the same time, it will cause the problem of flickering or blurred screen when the display device is turned on. The inventors of the present invention have found through research that one of the reasons for this problem is One is:

[0028] First, two operating modes of the control chip in the display device are introduced. According to whether a random access memory is provided, the control chip is divided into a control chip without a random access memory and a control chip with a random access memory. For the control chip without random access memory, its operating mode is video mode. The so-called "video mode" means that the control chip directly and real-time transmits picture information to the display screen. This mode can satisfy the internal timing of the display screen. higher requirement. For the control chip with random access memory, its o...

Embodiment 2

[0052] This embodiment provides a control method for a display module, such as image 3 As shown, the control method includes the following steps: power on the display module, then transmit preset pictures to the display screen of the display module, initialize the display screen at the same time, and lighten the backlight of the display module at the same time. That is to say, after the display module is powered on, the three operations of transmitting the preset image, initializing and turning on the backlight are performed simultaneously. The operation of transmitting the preset picture can be realized through the control device of the display module provided in the first embodiment.

[0053] It can be obtained from the above control method that after the display module is powered on, the preset picture is sent to the display immediately, so that the display immediately displays the preset picture. Although the initialization may not be completed at this time and the backli...

Embodiment 3

[0058]Based on Embodiment 1, this embodiment provides a display device, which includes a display module, a control chip, and a control device. Wherein, the display module includes a display screen and a backlight superimposed together; the control chip is connected to the display module; the control device is the control device of the display module described in Embodiment 1, and the control device is also connected to the display module .

[0059] The control device of the display module included in the above-mentioned display device can ensure a short start-up time when the display device is turned on, and avoid problems of flickering and blurred screens, thereby optimizing the performance of the display device.

[0060] In the display device provided by this embodiment, the control device can preferably be integrated on the control chip, so as to improve the integration degree of the internal structure of the display device.

[0061] It should be noted that the display dev...

Abstract

The invention provides a display module controller, a control method and a display device, relating to the display technical field, and solves the problems of splash screen and flower screen at start-up under the condition of not prolonging start-up time. The display module controller comprises a determination module and a storage module; the determination module is in connection with a voltage reference signal terminal; the determination module is in connection with the electrifying voltage signal terminal of a control chip; the determination module is used for determining whether a display module is powered on according to a voltage reference signal and an electrifying voltage signal; the storage module is in connection with the determination module, and is in connection with the display screen of the display module; the storage module is internally provided with preset pictures, and is used for transmitting the preset pictures to the display when the display module is powered on so as to allow the display screen to display the preset pictures. The display module controller is used for controlling the display module to immediately display the preset pictures once power is on.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a control device and control method of a display module, and a display device. Background technique [0002] Usually, the display device includes a display module and an external control chip connected to the display module, wherein the display module includes a display screen and a backlight source stacked together. When the display device is turned on, the display screen needs to be initialized and the backlight is turned on after power-on. In order to shorten the booting time, the two operations of initializing and turning on the backlight are usually performed at the same time, but this booting method often leads to problems of flickering or blurred screens when the display device is turned on. However, if you initialize the device before turning on the backlight, although it can eliminate the problems of flickering and blurred screens, it will undoubtedly prolong t...
