Embodiment Construction

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0041] As mentioned in the background technology, because of the convenience of HUD and the ability to improve driving safety, land vehicles such as cars have also tried to follow up the installation. Among them, the HUD projects the driving information of the car on the front windshield, and the driver looks at the windshield. When the windshield is turned on, the outside scene can be integrated with the car driving information displayed on the HUD, so that dr...

Abstract

The invention discloses a liquid crystal display module, its control method and a liquid crystal display device. The liquid crystal display module includes a liquid crystal display panel and a backlight for providing backlight for the liquid crystal display panel. There are a plurality of backlight structure areas, and each backlight structure area is provided with a light source for the sub-pixels connected to the corresponding data line group. Wherein, when the liquid crystal display module is driven, when all the data lines in the monitoring data line group do not transmit signals, the corresponding backlight structure area of ​​the data line group is driven to be in an extinguished state, and no voltage is applied to the backlight structure area. Wait for the driving signal to reduce the power consumption of the LCD module. By reducing the redundant power consumption in the working process of the LCD module, the problem of excessive heat generation of the LCD module can be improved, and the service life and performance of the LCD module can be guaranteed. good.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, and more specifically, relates to a liquid crystal display module, a control method thereof, and a liquid crystal display device. Background technique [0002] Head Up Display (HUD) first appeared on military aircraft. Head Up means that the pilot can see the important information he needs without looking down. HUD uses the principle of optical reflection to project important flight-related information on a piece of glass. This piece of glass is located at the front of the cockpit, and its height is roughly at the level of the pilot's eyes. The projected text and images are adjusted to an infinite focal distance. When the pilot looks in the direction of the glass, he can easily compare the external scene with the data displayed on the HUD mix together. [0003] Because of the convenience of HUD and the ability to improve driving safety, land vehicles such as cars have als...
