Character LCD

The number of different colors a display is able to show. Long description: A display can show a various number of colors, depending its hardware. Also known as color depth. The most common color depths are 18-bit (262K colors), and 24-bit (16.7 million colors).

A panel type refers to the technology used in creating the visual images on electronic displays. There are several different types of panels that are commonly used in displays, such as IPS (In-Plane Switching), TN (Twisted Nematic),VA (Vertical Alignment), VATN, MVA, AHVA, AMOLED, PMOLED etcetera.

A backlight is a light source used in a display to illuminate the pixels. It is typically located behind the display panel and shines through the pixels to make the image visible. A backlight is important for image quality, as it helps to ensure that the display is bright and visible even in low-light conditions. LED (Light Emitting Diode) is the most common used technology and the most energy-efficient technology used in backlights.

The power consumption of a backlight system on a display refers to the amount of electrical power required to operate the backlight and keep the display illuminated. The power consumption of a backlight system can also be affected by the settings and usage of the display. For example, increasing the brightness of the display will increase the power consumption of the backlight system, while decreasing the brightness will decrease the power consumption.

Display brightness refers to the amount of light that is emitted by a display screen. It is measured in candelas per square meter (cd/m²). The higher the display brightness, the more light is emitted and the easier it is to see the display in well-lit environments. Conversely, a lower display brightness makes the screen harder to see in well-lit environments, but may be easier on the eyes in low light conditions.

Display contrast ratio measures the difference in brightness between the darkest black and brightest white on a display, impacting image quality and visual performance. Higher ratios result in deeper blacks. OLED displays offer perfect blacks with self-lit pixels that switch off completely, providing infinite contrast ratios. IPS displays typically have a contrast ratio around 1,000:1 or slightly higher, while VA displays offer higher ratios of 3,000:1 to 4,000:1 at the high end.

The different techniques or methods which can be used to adjust and control the settings of a display. For example physical buttons, touch control options, UART (universal asynchronous receiver-transmitter) passive pen or a keypad interface or header. These control options allow the user to customize the display to their preferences like adjusting the brightness, contrast, color temperature and other image settings. All accessible via the on-screen display (OSD) menu or via buttons.

Display sizes are measured in inches diagonally across the screen from one corner of the display to the other.

The aspect ratio determines the shape of the display and affects the way that images and video are displayed on the screen. A display with a wide aspect ratio, such as 16:9, will have a more rectangular shape. A display with a narrow aspect ratio, such as 4:3, will have a more square shape. Which aspect ratio to use depends on the type of content that needs to be displayed.
