Description

LED panel display structure

technical field

The utility model relates to an LED panel display structure, in particular to an LED panel display structure which can control a plurality of light-emitting diode elements only through a single control chip, thereby achieving cost saving and unit resolution improvement.

Background technique

The LCD signal scanning method is one column at a time, and goes down column by column. The Gate Driver IC is connected to the Gate terminal of the transistors and is responsible for the switching of each column of transistors. When scanning, a whole column of transistors is turned on at a time. When the transistor is turned on (ON), the Source Driver IC can pass the control voltage for controlling brightness, gray scale, and color line by line into the pixels of the Panel through the channel formed by the Source terminal and the Drain terminal of the transistor. Because the Gate Driver IC is responsible for the switching of each column of transistors, it is also called Row Driver or Scan Driver. When the Gate Driver operates column by column, the SourceDriver IC is responsible for inputting the data voltage row by row in each column, so it is also called Column Driver or DataDriver.

Taking SXGA as an example, the resolution is 1,280x1,024, that is, the pixel matrix in the effective display area has a total of 1,280 rows and 1,024 columns. Since a single pixel must include the three primary colors of R, G, and B to display color, SXGA must have 1,280 x3=3,072 Column data. If the Gate Driver IC has 256 pins and the Source Driver IC has 384 pins, 1,024/256 = 4 Gate Driver ICs and 1,280x3/384 = 10 Source Driver ICs are required to drive an SXGA LCD panel. To drive XGA (1,024x768) with driver ICs with the same number of pins, 3 Gate Driver ICs and 8 Source Driver ICs are required, which is currently the most commonly used combination.

It can be seen that the higher the resolution, the more driver ICs are required, and so many driver ICs cannot be installed in a limited unit area, so it is impossible to realize a small-area high-resolution display.
