Segmented VA LCD Display Black Panel White Backlight HT1623 COB+PIN Module

Features of VA LCD Displays:

Vertical Alignment Technology:

• In a VA LCD, the liquid crystals are aligned vertically when no voltage is applied. When a voltage is applied, the liquid crystals align to allow or block light from passing through the panel, creating visible images.
• The vertical alignment of the liquid crystals allows VA displays to achieve better contrast ratios and deeper blacks compared to other LCD technologies, such as TN or IPS.

Superior Contrast and Black Levels:

• One of the main advantages of VA LCDs is their ability to produce deep blacks. This is due to the way the liquid crystals are aligned when the display is turned off. VA panels can block more light in the "off" state, resulting in superior black levels and high contrast ratios (often around 3000:1 to 6000:1 or more, depending on the model).
• Deep black levels make VA displays ideal for watching movies or content in dark environments.

Some Advantages of VA LCD Displays:

Wide Viewing Angles (Compared to TN):

• VA displays offer better viewing angles than TN (Twisted Nematic) displays, but their viewing angles are still more limited than those of IPS (In-Plane Switching) displays. While IPS panels offer near 180-degree viewing angles with consistent color reproduction, VA panels tend to lose brightness and contrast at wider angles but are still better than TN displays.
• The color shift in VA panels is less pronounced when viewed from the side compared to TN panels, but some degree of contrast reduction may occur when viewing from extreme angles.

Better Color Reproduction than TN:

VA LCDs have better color reproduction than TN panels, but they may not be as vibrant as IPS panels. While VA panels can still display rich colors, they tend to suffer from some color shift at wide viewing angles. However, the color shift is less noticeable than in TN displays, especially at moderate angles.

Faster Response Time than IPS:

VA LCDs typically have faster response times than IPS panels. This makes VA displays a good option for applications that require relatively fast refresh rates and motion handling, such as gaming and video playback. However, they may still exhibit some motion blur compared to TN panels, which have the fastest response times.
