I. Basic Concepts

The computer monitor is a crucial output device for computers, converting the image and video signals from electronic devices into visible optical images. Computer monitor technology encompasses various fields from its basic construction to advanced features.

II. Basic Structure The computer monitor is mainly composed of a display screen, a driver circuit board, and a backlight system. The display screen is the main part for displaying images, the driver circuit board controls the content displayed on the screen, and the backlight system provides the necessary illumination for the display screen. III. Display Technology 1. CRT (Cathode Ray Tube) Technology: This is the earliest display technology, which generates images by bombarding fluorescent substances on the screen with electron beams. 2. LCD (Liquid Crystal Display) Technology: Utilizing the physical properties of liquid crystals, it controls the transparency of light through voltage to display images. Most computer monitors still use this technology nowadays. 3. LED (Light Emitting Diode) Technology: A new display technology that uses light-emitting diodes as a light source, offering vivid colors, high brightness, and low power consumption. 4. OLED (Organic Light Emitting Diode) Technology: This is a self-emitting technology that does not require a backlight system, offering vivid colors and high contrast. IV. Advanced Features and Functions 1. Resolution: Represents the number of pixels that the display can show, with a higher resolution resulting in clearer content. 2. Refresh Rate: Represents the number of times the display updates per second, with a high refresh rate bringing smoother dynamic images. 3. Color Gamut and Accuracy: Represents the color range and accuracy that the display can present, which is crucial for applications such as graphic design and photography. 4. Touch Function: Some advanced monitors have touch functionality, allowing direct operation on the screen. V. Advanced Technology Analysis 1. Quantum Dot Technology: This is a new display technology that uses nanometer-scale quantum dot materials as a light source, enhancing color vividness and contrast. 2. Local Dimming Technology: By controlling the backlight brightness of each pixel, it achieves higher contrast and a richer black performance. 3. HDR (High Dynamic Range) Technology: By improving the detail performance in both bright and dark areas, it makes the image more realistic and three-dimensional.
