From the moment cathode-ray tubes became commercially available and used as display screens, the race towards immaculate resolutions became a primary objective amongst industry players. Cathode-rays were eventually displaced by plasma screens followed by liquid crystal (LCD) and eventually solid state devices such as OLEDs and LEDs the ‘world of resolution’ became rendered as ‘conquered’ because nothing was impossible. Coupled with advances in technology in the microprocessor and microelectronics field, industry professionals were able to give the world just about anything the masses demanded. This fact is mostly true mainly because of the inclusion of LED technology into the foray more than any other factor. Due to the level of flexibility that LED displays present, especially in regards to pitch pixel and component assembly, these displays offer a level of versatility like no other.
Facts about LED Displays & Their Popularity
dramatic evolution of television technology was the primary driver behind current screen technology for decades because just around 50 years ago, the only option that the masses had were black and white television. At present, the black and white television is seen as ‘antique’ items and production is basically non-existent and the colour television joined its ranks as soon as technology led to the introduction of screens that have incredible resolution such as the Fresno LED screens that project exceptionally high image quality and depth.
or light emitting diodes are basically a breakthrough in screen lighting and illumination technology. The special features that make LED screens as popular as they are and as technologically advanced as they are, is the stunning quality of LED pictures and colours. The level of contrast and depth that LEDs are able to output are in a league of their own as they offer almost near natural images that are inimitable by any other form of screen technology. Other factors that make LED screens preferred include their energy efficient systems, minimal space requirements and their durability. These characteristics have also made the demand for LED screens in the commercial arena increase by nearly 10 fold in just a few years.
LED screens for commercial use come in numerous varieties, from LED arches, LED Mesh, LED for Columns, LED floors and Ceiling and so much more. What makes these LED products unique is the fact that they could be configured and assembled into any shape and size and fitted practically on any surface seamlessly. Apart from that, their configuration is basically ‘À la carte’ meaning that clients are able to choose any type of LED screen product size, curvature, shape or resolution based on their needs.
For instance, Honeycomb Kinetics is an LED product that is ‘solid state’ and yet considered to be as flexible as Adhesive LED products that could be fitted on transparent surfaces such as windows. However, both products could be configured with almost any resolution due to the ability of the manufacturers to change the pixel pitch size from 1.0 mm right up to 5.0 mm or more. The pixel pitch size is what makes the difference in the quality of LED resolution which is dependent on viewing distance and angle. In essence, the smaller the pixel pitch (small pitch), the higher the resolution allowing close viewing distance at various angles without image ‘patching’.
FIt is ‘literally’ easy to see as to why small pitch LED displays seem to have distinct advantages over larger pitch sizes. Small pitch sizes such as 1 mm do not produce ‘patchwork’, project better colour tones and in general, even have longer lifespans. Although it comes at a higher price, when small pitch LED screens are concerned – satisfaction is guaranteed on ‘all points’. Although small pitch LED screens are more suited for indoor high-end applications within the ‘commercial scope’ due to its versatility and flexibility (small pitch screens are able to perform irregular display tasks that other screen types or large pixel pitch screen are unable to do), they are quickly becoming a regular element of option among ‘outdoor’ commercial screens. This leads us to the question of what exactly is pixel pitch size.
Pixel pitch generally describes the level of density of LED clusters on LED display screens and it is the pixel pitch size that primarily determines the resolution of a screen. The pixel pitch of an LED screen is the distance accorded in millimetres spanning from the centre of a given pixel to the centre of the pixel next to it. Thus smaller pixel pitch sizes simply mean that there is lesser space that is empty between pixels which equates to a higher level of pixel density leading to an enhanced screen in terms of resolution. This renders the pixel pitch ‘factor’ as an important element simply because it does not only enhances or reduces the quality of resolution but also has a significant impact on optimal viewing distance for LED display screens.
In essence, the smaller the pixel pitches size, the closer viewers are able to get to a screen without the projection being distorted. Smoother borders and finer details are the primary drivers behind the demand for lower pixel pitch measurements. Viewers will be able to stand at close range to the screen and still enjoy clear pristine images without being distracted by discerning individual pixels. However, it must be taken into consideration that a high level of pixel density is not the solution or the ideal option for every given scenario. This is mainly due to the fact that at great distances, screens that have higher levels of pixel density tend to lose image quality whilst at the same time increasing the cost of the display.
- Pixel pitch sizes are references to the density of pixels (the distance between pixels from their respective centres.
- Smaller pixel pitch sizes equate to screens that are higher in pixel density and therefore project at higher resolutions
- Pixel pitch sizes are critical towards determining viewing distances
- Smaller LED screen’s pixel pitch size – closer viewing distances
- Smaller pixel pitch size – higher cost
