Touch display can be said to be the new favorite of consumer electronic products, it not only has portability, but also has a good touch experience. So, how is the tft lcd touch display made?
First of all, the backlight of the tft lcd touch display is a very important part. The backlight is usually a large white light bulb, or a strip of LED lights. These backlights shine light onto a mirror, which is then reflected back onto the LCD display.
Second is the LCD itself. The LCD principle is very complicated, but it can be roughly understood as passing light through some specific liquid molecules, and then through a specific layer of crystal plates to generate light of different colors. Finally, these different colors of light are irradiated on the display screen to form the image we see.
A tft lcd touch display is formed by adding a layer of film on the LCD display. The film is conductive and has some specific circuit patterns.
Therefore, the screen has many different surfaces. In some cases, there will be some degree of curvature between the surface and the panel. If you place an object in front of the display, the top of the display will bend. The interface also bends when an object is behind the display.
There are touch buttons on both sides of the display to control the display content. The left is the physical button (onboard) and the right is the touch switch (clamp switches). The function of the touch switch is similar to the function of the button, and it is mainly used to control the display content and adjust the menu items.
Above the touch screen, a small LCD panel can be installed. The LCD panel can display information such as text, pictures and videos. Currently, many companies are developing touch technology that allows users to manipulate the display with their fingers.
