Character & Segment Displays

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.

There is a wide range of display technologies to create the visual images that appear on displays. The most used display technologies are LCD and OLED in the industrial market.

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).

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 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.

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.
