Display Modules - LCD, OLED, and Graphic

Display Modules are used in a variety of applications and can be found in nearly every industry. Manufacturers commonly use these modules to provide information, display images, and consolidate data. There are three main types of modules: LCDs, OLEDs, and Graphic. Each of these has its own unique properties that make it suitable for certain applications.

LCDs

Liquid Crystal Displays (LCD) are a type of display module commonly used in applications that require an excellent picture quality and low power consumption. LCD modules feature an array of small liquid crystals enclosed between two plates of polarized glass and are typically found in digital watches, cameras, televisions, computer monitors, and mobile phones. An LCD display works by controlling the polarization of the polarized glass which then affects the alignment of the liquid crystals. This allows the LCD to display different images as the polarization is changed.

OLEDs

Organic Light Emitting Diode (OLED) is a display module that uses an organic material that emits light when a voltage is applied to it. OLEDs differ from LCDs in that they use a series of organic compounds of carbon and nitrogen instead of a liquid crystal solution for producing the image. They are typically used in flat-screen televisions and mobile phones, where their ability to produce brighter images gives them an edge over LCDs.

Graphic

Graphic displays are a type of display module used in applications like game consoles, navigational systems, barcode scanners, and interactive kiosks. Graphic displays are composed of an array of rows and columns of individual pixels on the screen that created an image. These pixels are each assigned a specific color which is used to create the image. The advantage of a graphic display is that the images can be created dynamically, allowing for animations and even interactive features depending on the type of display used.

These are the three main types of display modules used in applications today: LCDs, OLEDs, and Graphics. Each of these has its own unique properties that make it suitable for certain applications. LCDs are excellent for applications where image clarity and power consumption are important, OLEDs provide brighter images and have wide usage in mobile devices and televisions, and Graphics are well suited for game consoles, navigational systems, barcode scanners, and interactive kiosks.
