Problems solved by technology
[0004] However, there is an obvious defect in the existing liquid crystal instrument display device. Because the highest brightness that the liquid crystal screen can display is limited, when strong light (such as strong sunlight) shines on the surface of the liquid crystal screen, it will be difficult for the driver to distinguish the light on the liquid crystal screen. Display information, thereby affecting driving safety

The invention discloses a liquid-crystal dashboard display device used for a vehicle. The liquid-crystal dashboard display device comprises a liquid-crystal screen, a black edge area, brightness sensors and LED displays, wherein the black edge area is positioned around the liquid-crystal screen; the brightness sensors are integrated in the black edge area and used for detecting the brightness of external light; and the LED displays are integrated in the black edge area. When the brightness of the external light detected by the brightness sensors exceeds a set threshold, the LED displays operate to display information related to the driving safety of the vehicle. When the brightness of the external light detected by the brightness sensors does not exceed the threshold, the LED displays stopoperating. In the liquid-crystal dashboard display device used for the vehicle, when the brightness of the external light exceeds the set threshold, the LED displays display the information related to the driving safety of the vehicle with high brightness, so that a driver can obtain the information related to the driving safety of the vehicle even in the case of exposure to intense light so as to ensure the driving safety.
Description
technical field [0001] The invention relates to the field of automobiles, in particular to a liquid crystal instrument display device for vehicles. Background technique [0002] With the maturity of technology and the decline of cost, more and more new vehicles begin to adopt liquid crystal instrument display devices. The liquid crystal instrument display device has a more technological sense, and can more flexibly define display themes through software. [0003] figure 1 The liquid crystal instrument display device in the prior art is shown in . The liquid crystal meter display device includes a central liquid crystal screen 1 and a black edge area 2 around the liquid crystal screen 1 . When not working, there is no color difference between the liquid crystal screen 1 and the black edge area 2 . When working, the LCD screen 1 is lit to display information. [0004] However, there is an obvious defect in the existing liquid crystal instrument display device. Because the...
