Driver interface
The LCM provides users with a standard LCD display driver interface (4-bit, 8-bit, VGA, etc.). Users can perform operations according to the interface requirements to control the LCD display correctly. Compared with glass, LCM is a more integrated LCD product. For small LCD display, LCM can be easily connected with various microcontrollers (such as single chip microcomputer). However, for large size or color LCD display, it generally occupies a considerable part of the resources of the control system or cannot achieve control at all. For example, the color LCM of 320×240 256 colors is displayed at 20 fields/second (that is, the full screen refresh display is 20 times in 1 second), and the amount of data transmitted in one second is as high as: 320×240×8×20=11.71875Mb or 1.465MB, if the standard MCS-51 series microcontroller processing, assuming the repeated use of MOVX instruction continuous transmission of these data, considering the address calculation time, at least need to connect to 421.875MHz clock to complete the data transmission, You can see the huge amount of data processed.
The resolution of fax is also the scanning density. The higher the resolution is, the higher the scanning accuracy is. It can be divided into vertical resolution and horizontal resolution. Vertical resolution refers to the number of pixels per millimeter displayed on the vertical horizontal line, and horizontal resolution refers to the number of pixels per millimeter displayed on the parallel horizontal line. According to the international standards of three types of fax machines, the horizontal resolution is 8 pixels /mm, so the resolution of fax machines is generally expressed as 8 pixels /mm× vertical pixels /mm. Generally, we omit the horizontal resolution and only express the resolution in vertical resolution. The vertical resolution mainly includes three types: standard 3.85 pixels /mm, fine 7.7 pixels /mm, and hyperfine 15.4 pixels /mm.
LCM process
Liquid Composite Molding (LCM) process, refers to the liquid composite molding (RTM, RFI and RRIM) technology. Its main principle is to first lay in the mold cavity according to the performance and structure requirements of the designed reinforced material premolding body, using injection equipment to inject special injection resin into the closed mold cavity or heated melting mold cavity resin film. The mold has peripheral sealing and fastening, injection and exhaust systems to ensure the smooth flow of resin and discharge all the gas in the mold cavity and thoroughly infiltrate the fiber, and the mold has a heating system to heat curing and forming composite components.
