OK202-25-USB-OY Application Field and Working Principle

OK202-25-USB-OY is one of the various models of display modules available in the market that are classified in the category of LCD, OLED Character & Numeric. It is also known as LCD Module & COG Graphic. This display module is a member of a family of display devices that allows the user to show text or graphics on a screen where it can be seen. It is typically composed of an LCD panel, which is the actual display device, and the backlight, which provides the lighting for the LCD panel so the user can read the available content.

This display module can be found used in a variety of devices like commercial products, such as cellular phones, digital cameras, PDAs, laptops etc. Other than this, they also find applications in medical equipment, automobiles, as well as general embedded systems. When it comes to the industrial realm, these display modules are extensively used in automation and process control.

Working Principle of OK202-25-USB-OY Display Module

The display module basically works by utilizing LCD technology. This technology uses an array of thin film transistors (TFTs) placed between two sheets of glass. The TFTs are composed of three thin film layers—the first layer is a substrate of a semiconductor, the second is a gate dielectric layer, and the third is a thin film of semiconductor material. This layered structure allows the TFT to be driven in combination with the other pixels to selectively change the viewing angle of the LCD panel.

When light passes through the LCD panel, it is either transmitted or blocked depending on its orientation. This indicates whether each pixel is on or off. By changing the orientation of these pixels, different shapes can be created. The LCD panel works by changing the electric field between the layers to control the orientation of the pixels, thereby controlling the pixel state. This allows the user to create a picture out of the array of pixels.

Advantages of OK202-25-USB-OY

The OK202-25-USB-OY display module has a range of advantages over its predecessors. Firstly, it is thin and lightweight, which makes it more mobile, and more suitable for a variety of applications.
