The graphic lcd module manufacturer tells you that each type of LCD liquid crystal display module is now named after its liquid crystal display dots, such as 12864, which is actually an array of 128 columns and 64 rows. The graphic lcd module manufacturer tells you that every model of LCD liquid crystal module will have some of its parameters. Let’s take 12864 as an example to take a look at some of its principles.
12864, each display point corresponds to a binary number, 1 means on, 0 means off. The graphic lcd module manufacturer tells you that the RAM that stores these dot matrix information is called display data memory. When a certain figure or Chinese character is to be displayed, the corresponding dot matrix information is written into the corresponding storage unit. The graphic lcd module manufacturer tells you that the dot matrix information of graphics or Chinese characters must of course be designed by yourself. The key to the problem is the situation between the position of the display point on the LCD screen and its address in the memory.
The graphic lcd module manufacturer tells you that because most of the drive circuits of LCD modules are composed of one row driver and two column drivers, the 12864LCD screen is actually composed of two independent 64*64 LCD screens on the left and right. Spliced together, each half screen has a 512*8 bits display data RAM. The driving circuit and the memory of the left and right half screens are respectively selected by the chip selection signals CS1 and CS2.
The graphic lcd module manufacturer tells you that the position of the display point on the 64*64 LCD screen is determined by the line number (line, 0~63) and the column number (column, 0~63). The address of a memory cell in 512*8 bits RAM is determined by the page address (Xpage, 0~7) and the column address (Yaddress, 0~63). The graphic lcd module manufacturer tells you that each storage unit will store about 8 liquid crystal dots of display information.
The graphic lcd module manufacturer tells you that in order to make the correspondence between the position information of the liquid crystal dots and the storage address more intuitive, the 64*64 LCD screen is divided into 8 display blocks from the top to the bottom, and each block includes 8 The number of dots in rows * 64 columns. The graphic lcd module manufacturer tells you that the 8-row dot matrix information in each column constitutes an 8-bit binary number, which is stored in one of the storage units. It should be noted that the corresponding relationship between the high and low significant bit sequence of the binary system and the line number is different for different businesses.
