The concept of photoelectric parameters

LCM photoelectric devices include LCD PANEL (LCD PANEL, LCD screen, LCD glass, integrated LCD) and backlight. LCD is a kind of optical switch, which can control the performance of light through, partially through, and not through when it is powered on. In essence, it is a device that modulates light flux under the action of electricity. BL is a light emitting device that turns the light emitting diode into a surface light source, which is the main light source of LCM.

Basic structural parameters of LCM

AA area: effective display area VA area: Effective visual area, VA and AA area together determine whether the product can be matched to the customer panel window. Positioning hole distance: it is related to whether the product can be assembled with the positioning hole on the motherboard. Positioning hole size: it is related to whether the positioning hole diameter of the product can use the customer's screw. Position of VIEWable AREA: THE position of VIEWable AREA in XY direction is related to whether the product can be installed in the same position as the customer panel window. Interface size: It is related to whether it matches the connection method of the customer. Interface location: It is related to whether the customer can be used when the connection mode is hardwired. Dimensions above the PCB board: whether the product in the Z direction affects the installation. Iron shell shape. Product shape.

Characteristics of LCM

Flat panel display, small size, light weight. The working voltage is low and the power consumption is small. The working voltage of the simple broken code LCD is 2-5V, unit surface The power consumption of the product is about 0.01uA/mm², and a button battery can be used for two or three years. The life is relatively long, generally can reach more than 50,000 hours. Electromagnetic radiation is low, harmless to human body, not easy to cause eye fatigue. It is passive luminescence, not easy to be washed by strong light, the stronger the external light, the clearer the display. Easy to drive, using a simple single chip microcomputer can be driven, simple and convenient. Simple structure Single, no complex mechanical structure.

The basic concept and characteristics of LCM

LCM (LCD Module), namely LCD display module (block), refers to the LCD glass, LCD driver (IC) and the connection part integrated together LCD display product, it provides the user with a standard LCD display driver interface (serial port, parallel port and other different types), The user operates according to the interface requirements to control the LCD to display correctly. LCM compared with LCD is a higher integration of LCD products, LCM can be more convenient with a variety of microcontrollers (such as single chip microcomputer) connected to form a display system.
