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...
