OLED technology, or Organic Light Emitting Diode technology, is a display technology that uses organic compounds to emit light when an electric current is applied, allowing for thinner, more flexible, and energy-efficient screens compared to traditional LCDs. This technology enables superior color accuracy, faster refresh rates, and deeper blacks, making it ideal for high-quality displays in smartphones, televisions, and other electronic devices.
Display resolution refers to the number of distinct pixels that can be displayed on a screen, impacting the clarity and detail of the visual output. Higher resolutions provide sharper images but require more processing power and can affect performance and compatibility with content and devices.
Light-Emitting Diodes (LEDs) are semiconductor devices that emit light when an electric current passes through them, offering high efficiency, long lifespan, and low energy consumption compared to traditional lighting technologies. They are widely used in various applications, from household lighting to display screens, due to their ability to produce a wide range of colors and their robustness.
Image processing involves the manipulation and analysis of digital images to enhance their quality or extract valuable information. It is a crucial technology in fields like computer vision, medical imaging, and remote sensing, enabling advanced applications such as facial recognition, object detection, and image restoration.
Color calibration ensures that colors are consistent and accurate across different devices by adjusting the color output to match a standard reference. This process is crucial in industries like photography, printing, and digital media, where precise color representation is essential for quality and consistency.

Luminance is a photometric measure of the luminous intensity per unit area of light traveling in a given direction, quantifying how much light is emitted, reflected, or transmitted from a surface. It is crucial in fields like photography, television, and vision science as it influences the perceived brightness of an image or scene.
Contrast ratio is a measure of the difference in luminance between the brightest white and the darkest black a display can produce, influencing the perceived quality and readability of the image. A higher Contrast ratio generally indicates better picture quality, with more vivid colors and deeper blacks, which is crucial for tasks requiring visual clarity and detail discernment.
Pixel density refers to the number of pixels per inch (PPI) on a display, determining the sharpness and clarity of the image. Higher Pixel density results in finer details and smoother edges, enhancing the viewing experience, especially on high-resolution screens.
An active matrix is a type of addressing scheme used in displays, such as LCDs, where each pixel is controlled by its own transistor, allowing for higher resolution and faster response times compared to passive matrix displays. This technology enables more precise control over the display's pixels, resulting in better image quality and the ability to display complex images and videos.
Self-emissive displays are a type of display technology where each pixel emits its own light, allowing for deeper blacks and higher contrast ratios compared to transmissive displays. This technology is commonly used in OLED and MicrOLED screens, offering energy efficiency and superior image quality due to the absence of a backlight.
