Hello, guys welcome back to our site, Today here in this post I will tell you about What is VCOM Voltage in LCD LED TV All Information. If you want to know about this VCOM voltage this is the right place for you.
Especially we focused on LCD LED TV VCOM voltage because the VCOM voltage we get voltage control oscillator. And the Voltage control oscillator technology we see in the LCD LED TV panel also where we get VCOM voltage. So all these things are interconnected.
Now we would like to tell you about our service. Here on this site, we share electronics-related information and electronics gadgets repairing techniques. If you need any information about repair any kind of electronics gadgets, just comment down below and explain your problem. We will reply to you with a solution within two or three days.
It is the reference voltage of the LCD panel. VCOM amplifier is specifically designed to drive TFT panel loads. Its peak output current of 300 mA and the peak output voltage is 3.3v. The VCOM voltage is typically adjusted during the manufacture of the display to get the highest image quality. VCOM voltage is the common voltage of any panel. The voltage of VCOM fluctuates according to variations of gate and data voltage.
How to Generate a VCOM Voltage?
VCOM Voltage generates Using a PWM ( Pulse Width Modulation ) Signal. It is a simple and easy way to generate VCOM Voltage. PWM signal is the input of the microcontroller and we get analog VCOM Voltage.
The function of VCOM Voltage
1) VCOM Voltage circuit has a buffer. that buffer can adjusted VCOM Voltage
2) It provides a way to adjust the VCOM voltage
The problem for VCOM Voltage Missing in Panel
We get a White Display Problem inside the TV panel because of missing this Vcom voltage inside the TV panel. So If you get a white Display Problem in your LCD LED TV then you have to check this voltage on the panel scaler PCB on the Panel source PVB
Full form of VCOM Voltage
Common Voltage To Operate the Panel. This is the full form of Vcom Voltage. And if you want to know more about this voltage just comment down below I will update your data on this post.
