Lcm provides users with a standard lcd display driver interface (with 4 bits,8 bits, vga, etc.). Users operate according to interface requirements to control lcd display. Lcm comparison glass is a more integrated lcd product, for small size lcd display, lcm can be more convenient to connect with various microcontrollers (such as single chip); however, for large size or color lcd display, it will generally occupy a considerable part of the control system resources or simply cannot achieve control, such as 320×240×256 color color lcm, in 20 field/second (i.e.1 second full screen brush display 20 times) display, only transmission of the amount of high:320×240×20×8×11= mb7. The resolution of the fax is also the scan density, the higher the resolution represents the higher the accuracy of the scan.
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 standard of the three types of fax machines, the horizontal resolution is 8 pixels / mm, so the resolution of the fax machine is generally expressed as 8 pixels / mm × vertical pixels / mm. Generally, we save the horizontal resolution and only use the vertical resolution to represent the resolution. vertical resolution is mainly standard 3.85 pixels/mm, fine 7.7 pixels/mm, ultra fine 15.4 pixels/mm three kinds. The lcm process (liquid composite molding) refers to the liquid composite technology represented by rtm, rfi and rrim. The main principle is that the preform body of reinforced material designed according to the properties and structure requirements is first laid in the mold cavity, and the special injection resin is injected into the resin film in the closed mold cavity or heated melting mold cavity by injection equipment. The die has a peripheral seal and fastening and an injection and exhaust system to ensure smooth flow of resin and discharge of all gas and thoroughly infiltrated fibers in the die cavity, and the die has a heating system for heating curing and forming composite components. lcm (liquid crystal module), or liquid crystal module.
