A bar type LCD refers to an LCD screen with an aspect ratio of more than 3:1, giving it an ultra-wide viewing angle experience, high brightness (sunlight readable), and sharp colors. This makes it ideal for applications where you need to display a lot of information in a small space, such as point-of-sale systems, retail displays, and digital signage.

There are a number of parameters that are important to consider when choosing a bar type LCD screen. These include:


The resolution is the number of pixels that it can display. Higher-resolution screens will provide sharper images, but they will also be more expensive.

Viewing angle

The viewing angle of a Bar Type LCD is the angle from which the user can still see the image clearly. Wider viewing angles are important for applications where the screen will be viewed from multiple angles, such as in retail stores.


The brightness of a wide bar type LCD is the amount of light that it can emit. Brighter screens will be easier to see in well-lit environments, but they will also consume more power.

Contrast ratio

The contrast ratio of an LCD stretched bar is the difference between the brightest and darkest colors that it can display. Higher contrast ratios will provide more vivid images.

Response time

The response time of a wide bar LCD is the time it takes for the pixels on the screen to change from one color to another. Faster response times are important for applications where the screen will be used to display fast-moving images, such as in gaming.

Screen ratio

The screen ratio of a stretched bar LCD is the ratio of its width to its height. Stretched bar LCDs typically have a screen ratio of 3:1 or higher.
