With the development of touch screen technology, many cameras use touch screen. The touch screen of digital camera has capacitive screen and resistive screen like mobile phone. Older cameras have resistive screens. One of the biggest differences between a digital camera and a traditional one is the fact that it has a screen that allows you to view images in real time. This is called a digital camera Display and is usually called a Liquid Crystal Display (LCD) . Commonly used digital camera LCD is TFT type, what is TFT in the end? Firstly, it includes polarizing plate, glass substrate, thin mode transistor, alignment film, liquid crystal material, guide plate, color filter plate, fluorescent tube and so on. In the case of liquid crystal display, the backlight comes from fluorescent tubes that pass through a polarizer and then through a liquid crystal, where the molecules are arranged in such a way that the angle at which the light passes through the crystal changes. When using LCD, we find that different colors and contrasts can be seen from different angles. This is because most of the light coming off the screen is vertical. If we look at an all-white image from a very oblique angle, we may see black or color distortion.
