ABSTRACT:
The present invention relates to a liquid crystal display for a vehicle and, particularly, to a liquid crystal display which adjusts liquid crystal drive voltage based on the temperature of a liquid crystal display panel so that the contrast of the liquid crystal display panel is optimum. The display includes a liquid crystal display panel, a circuit board for mounting circuit elements including a liquid crystal driver, a temperature sensor mounted on the circuit board, and a control circuit for controlling liquid crystal drive voltage based on temperature detected by the temperature sensor. The liquid crystal display panel and the circuit board are arranged parallel to each other in a meter housing with a predetermined space therebetween. The display also includes an exposed heat collection panel arranged to surround the screen of the liquid crystal display panel. This configuration provide a liquid crystal display for a vehicle capable of controlling liquid crystal drive voltage accurately without mounting a temperature sensor on the liquid crystal display panel.
