First, classify from the effect of electro-optical (thermo-optical)
1. Commodity classification
In the practical process, sometimes it is not necessary to follow the principle. The structure is to distinguish its category, and more is to distinguish it from some angles of the product, the display method and the performance of the display. This kind of LCD classification is more practical in application.
1. Commodity form
(1) Liquid crystal display devices: some liquid crystal display devices including the front and rear polarizers, referred to as LCD.
(2) Liquid crystal display module: Commodities including already assembled circuit boards, IC driving control circuits and other accessories are referred to as LCM for short.
2. The way of display
(1) The display of the positive image: a product with dark content displayed on a light background.
(2) Negative image display: a product that displays light-colored display content on a dark background.
(3) Transmissive display: a product that the back-illuminated light source passes through the device, so that the observer who observes from the front can see it.
(4) Reflective display: a product in which the observer and the external light source are on the device side.
(5) Semi-transmissive display: The back light reflective film of this type of product is equipped with meshed pores, which can completely transmit 30% of the backlight light, so it can be used as a reflective display during the day and at night. Can be used as a transmissive display.
(6) Monochrome display: black and white display
(7) Color display: It can be divided into single-color display and multi-color display, and in the multi-color display, it can be divided into pseudo-color display, that is, only 8 to 32 colors can be displayed. The true color display, that is, it can display 256 colors to hundreds of thousands of colors.
3. Display performance mode
(1) Normal temperature display: 0°C~50°℃ is its working temperature, -20°C~60°℃ is the storage temperature—a type of product.
(2) Wide temperature display: that is: -20C~70℃ is its working temperature, -30°℃~80°℃ is the storage temperature-a kind of product.
(3) The integer display is a product that relies on long strip pixels to display, and can only display numbers and some individual characters.
(4) Dot matrix LCD display: a product that relies on rectangular pixels for display, which can display any characters, numbers and graphics.
(5) Character display: a dot matrix product that can only display divided characters.
(6) The number of graphic display dot matrixes is relatively large, and the pixel pitch is equal, which can display various graphic dot matrix products.
(7) Image display: One of the graphic display products, because of its fast response speed, it is possible to display image products with video speed activities.
