lcd display congealing used to improve security and reliability

In terms of performance, TFD both the TFT LCD liquid crystal screen and the advantages of the lcd display  screen, TFD LCD is higher than the STN LCD screen brightness, and color is more bright-coloured, more power saving than TFT LCD screen at the same time, but in the color and brightness is worse than TFT LCD.
As TFT technology maturity in the COG LCD Display early ninety s, color LCD flat panel display is developing rapidly, less than 10 years, rapid growth TFT - LCD display for the mainstream, and it has the advantage of this is inseparable. The main features are:
(1) use good features: low voltage application, low driving voltage, congealing used to improve security and reliability; Flat, thin, save a large amount of raw materials and the use of space; Low power consumption, its power consumption is about one over ten of the CRT display, reflection type TFT - only about one percent of the Character LCD Modules lcd display and even save a large amount of energy; TFT - LCD products and specifications, size series, species diversity, convenient and flexible to operate, easy to maintenance, updates, upgrades, long service life and many other features. Display range covered the range from 1 inch to 40 inches all the display and the application scope of the projection plane, is a full size display terminal; Display quality from the simplest monochromatic character graphics to high resolution, high color fidelity, high brightness, high contrast, high response speed of various types of video display; Display mode has a look, projection, type of perspective, there is also a reflection.

Since this command system and lcd display drive controller compatible

Software programming language using Keil C51 driver includes a display module hardware (ie write commands and write data), and clear screen display module initialization routines as well as other common Western character display realization process. Since this command system and lcd display
 drive controller  compatible, so these procedures have a high versatility. For character character display COG LCD Displaycharacter features of the module library data is prepared in the form of columns of data that a byte of data represents the data of an 8 × 1, and compared with the usual character library, the character is rotated by 90 ° font data. Use Zimo21.exe take matrix software, and set the mode to portrait modulo Coding System lcd module extraction, you can easily obtain the necessary Western text mode. Since each column of data to the display module 8 × 1 is the low front, high in the post, in order to further achieve the correct display of Chinese and Western culture, the need for each byte matrix obtained by the above method to conduct a swap of high and low , the program uses an array UpsetChar  to achieve. Western character used in the program is 16 × 8 dot matrix, character is a 16 × 16 dot matrix.
