Matrix is the arrangement of pixels/dots that make up the LCD screen. A row of LEDS are as common as running text viewer with LED lights which are also arranged form a matrix. The example displays running text size 6 x 6 LEDS, it means there is a total of 36 led (6 multiplied by column 6 line). Each of these LEDs connected in matrix based on column and row. In the picture, which was given the green color was a column, are given the color yellow is line.
Matrix can also be found in a series of keyboard keys, the goal is summarizing the number of cables. Example as in the picture below (is a series of remote control from datasheet HT6221), consists of 4 lines x 8 column, a total of 32 buttons. Imaginable when given a separate cable key individual commandments themselves, then there will be 32 separate cable and this makes very ineffective (whereas in Figure 4 only + 8 cables only). On this matrix keyboard, IC will do the scanning/search button that is pressed by the way read the condition column/row. For example, IC will select line 1, and then read the column, when there is no pressed, then the IC will be shifted to the line to 2, then read the column, when there is no pressed, then ICS will select rows 3 and so on. If there is a button oppressed, must surely know where pixels button/push by noting "coordinates".
Even DOT-MATRIX printers such as the EPSON LX-300 + matrix based work also consists of 9 pin/dot vertical. So technically, the LED matrix LCD and keyboard matrix is the same. the key word is the number of pixels/button/dot, columns, rows and scanningnya way.
The LCD screen is a collection of dots (dots) liquid crystal that forms the matrix with a specified size. Matrix composed of columns and rows, as in the math lesson about the matrix. When it is analogous with a square, then think of the column is the width of the line is, being in length. While the 1 point elements called pixels. So when there is a LCD with 320 x 240 pixels, size means there are 320 width a point multiplied by the length of the period, a total of 240 76800 dots/pixels.
Because it consists of columns and rows, then the controller required columns and rows. Often referred to as Row and Column Drivers drivers. When the column drivers in trouble, surely will be featured pictures with damage to a straight line from top/bottom (part or whole). When damage to the row, then the driver will perform damage with a line from the left/right (part or whole).
Memory area also Comprises the order of Matrix
Memory (flash, eeprom, ram, etc.), also using the matrix in it. Take for example the eeprom memory 24C01 in 128 Byte capacity datasheet (1 byte = 8 bit) so the total overall into 8 columns x 128 line so that a total of 1024 bit/point. Matrix 8x128 is connected to the Decoder Address (address translator) and Buffer data, so, through its memory can be directly read/write the contents of the memory at a specific address. As well as on the LCD display, the data received by the t-con will be translated into a data column and row, can finally be shown. On the panel/lcd screen, the system only write alone, there need be no readings. So it's different on the type of RAM memory is could read and write.
