LCD LED TV Tcon Voltages Data

VGH, VGL, VCOM, and AVDD voltage for TFT LCD

Most of the large TFT LCD panels out there require several bias and logic voltage levels to drive them, such as VGH, VGL, VCOM, AVDD, DVDD, etc. If the TFT display already has a driver board attached, it will most likely already have the means to product all these signals. But if you are using a display that only has a flat flex cable and needs you to supply these different voltage levels, you have no choice but to generate them in your circuit and provide the voltage levels.

What is tricky is keeping the cost of the design low. It is not at all efficient to use multiple boost converters to generate all these voltage levels. Also, making discrete transistor based boost converters can cause noise, flicker and sub-optimal performance of the display.

 

In this article, we provide a schematic to generate common VGH, VGL, VCOM, and AVDD rails from a single input voltage.

Common VGH, VGL, VCOM and AVDD voltage levels

TFT LCD panels always have a controller in there which is a CoG (chip on glass) type IC planted on to the panel to drive the rows and columns. The chip has referenace values and tables to drive the display to get the desired contrast and bias voltage needed to control the LCD pixels properly. Incorrect values can cause the panel to look low contrast and weak, or in the other extreme case cause permanent damage to the panel.

The CoG controller IC datasheet usually specifies a range of VGH, VGL, VCOM and AVDD values as absolute maximum rating. As a designer you must ensure that those values are not exceeded. Because the current draw is very little on VGH, VGL and VCOM, overshoots can be a problem in poorly designed circuits.

In addition to this, the LCD manufacturer configures the CoG LCD controller to use certain bias voltages that match the LCD panel characteristics (all LCD panels are not exactly the same). Here is an example from a 7″ display datasheet (ER-TFT07-2) with RGB interface.

Example of VGH, VGL, VCOM, and AVDD specifications for 7" TFT LCD panel

In most cases, the VGH level is going to be less than twice the AVDD level. VGL magnitude will usually be less than AVDD as well, but it will be negative.
To generate all these power rails, one can simply use a single boost converter to generate AVDD and use the switching function to operate charge pumps that generate the other voltage rails. VGH and VGL rails do not draw a lot of current and are easy to regulate using “discrete” linear regulator circuits as we will describe in the next section.
