Consulting with An LCD Manufacturer About the Different LCD Types

An LCD Manufacturer Can Tell You About Different LCD Types Available

Anyone intending to invest in LCD modules would do well to know what options are available out there on the market. There are various uses for LCD’s, such as viewing displays, handheld applications with touchscreen surfaces, or as part of a larger, more intricate security system like a biometrics machine.

Having basic knowledge of the available options can make it easier for you to get a better idea of what suits your needs best.

LCD Display

LCD is short for Liquid Crystal Display. This display is very common in the market, especially in the form of notebooks, tablets, and other handheld devices. It is also popular as a TV display option. As its name suggests, LCD relies on liquid crystals switching on and off in order to rotate polarized light. Primarily, they come in either passive or active technologies.

Passive Displays

This type of LCD is most commonly used for devices with small readouts. For example, security biometrics devices, calculators, remote controls, and similar devices use passive displays. They only function to make information or data viewable to the user, and are characterized by a narrow viewing angle.

Because of this simplicity in makeup, passive displays are less expensive than other LCD types. Manufacturing takes less steps for development as well since activating rows and columns require transistors–it doesn’t have to be for each subpixel. If there’s one thing that you should be wary of about passive displays, it’s that it suffers from a common problem of “submarining”, or that instance when the cursor disappears from view when it is quickly moved. Types of screen colors for passive displays usually include monochrome TN, STN, and FSTN.

Active Matrix Displays

This is used for bigger applications such as tablets, smartphone screens, and other touchscreen gadgets. The display is meant to be a lot more sensitive to improve response time, especially because it is meant to facilitate action through command. Therefore, active matrix displays have less propensity for having submarining problems. Active matrix displays use TFT, or thin film transistors that are located directly behind the screen.

The bigger size of the display also requires it to have brighter resolution and sharper contrast. Active displays also use backlight, making them more conveniently used for reading or viewing. They tend to become too bright, especially in the dark. This is why recent developments in the technology has implemented the use of blue light filter, to soften the harshness of the backlight, particularly when the device is used in the dark.

With this information, you can determine better which type of display suits your needs best. Then you will not be overwhelmed by the range of choices offered by an LCD manufacturer.
