In the process of daily use of the car, we need to always understand the state of the car, to avoid damage to the important parts of the car, but also to eliminate potential dangers. Often, the information displayed on the dashboard is a way to know the state of the vehicle. https://www.findhorizon.com/

LCD displays are a bit more energy-efficient than OLEDs. Energy consumption in OLED displays depends on the screen brightness. Less brightness used means lower power consumption, but this may not be ideal because the contrast ratio will suffer when brightness is reduced. This is not ideal if, for instance, you’re using an OLED smartphone under bright sunlight. https://www.findhorizon.com/

However, the clarity of images and videos can’t match that of OLEDs when viewed from extreme side angles. This is because LCDs inherently block light due to their filtering layers, and that creates added depth which makes LCD viewing angles limited. tft display https://www.findhorizon.com/
