Display technology has rapidly evolved over these years by showcasing monitors of different sizes and shapes with constantly improving image quality attributes. Understanding the differences between the backlight implementations helps to get a clear view of various modern displays.
LED screens come in various types, each with unique features and advantages.
- Surface-Mounted Device (SMD) LED screens
SMD LED display is a matrix of light-emitting diodes, which are also known as flat panels as they have no curved edges like LCD screens. Such types of screens are ideal for indoor and outdoor advertising displays due to their high ambient lighting levels. Moreover, SMD’s are installed on printed circuit boards with automated machinery making them more affordable than any other screens
- Digital Light Processing (DLP) LED screens
These displays, on the other hand, reflect light and produce images using tiny mirrors, making them perfect for big spaces like sports arenas and music hall.
- Liquid Crystal Display (LCD)
LCDs have been widely used for decades and are still on the display market without dimming-out their fame. The light emitted from backlight of the device passes through the liquid crystal layer, where it gets modulated and forms the final image on the screen. An LCD panel with an LED backlight composed of an array of LEDs.
- Dual – Layer LCD
In a dual–layer or dual-cell LCD, two ‘light modulating’ layers are placed between the panel and backlight. The second layer is for emulating local dimming by modulating the light that passes through it. The light modulating layer allows for pixel-level control that is advantageous in contrast ratios and black levels.
- Organic Light Emitting Diode (OLED)
OLED is a newer technology with millions of pixels, and each of them in the array is its light source. Therefore, there is no need for a backlight in OLED and it allows for much deeper back performance. The technology of OLED also allows for a much thinner overall design.
How Display technology Works?
The images are rendered on a display when the CPU sends the image data to a Graphic Processing Unit (GPU). The GPU is integrated into the motherboard or the CPU. The image data is then translated by the GPU and transmitted to the display. In this process, GPU must perform intensive computational functions to ensure that the display receives the exact representation of the screen image. The image is then rendered by the display from a sequence of bits that describe the color values of X and Y coordinates starting from a location on the screen.
At present image information can be sent to a computer display as a digital signal. The graphics card that supports analog connectivity must convert the digital display signals to analog data so that the image is rendered in the display. An integrated display helps to establish connectivity through the computer’s architecture.
