What is an LED display?

LED display or LED sign is an electronic sign consists of a matrix of individual LED lights (LED pixels) that make image, text or video together. LED pixels are placed very close together and from relatively far distance the eyes won’t be able to see the gap between the pixels result in an acceptable image quality with minimum pixilation. Compare to LCD digital signage (like TV), LED signs and LED displays provide lower resolution due to lower number of pixels. But, brightness and color production is much more eye-catching which is necessary for outdoor and behind the window digital signage.

Viewing Distance

The most important factor of LED signage is viewing distance. If your sign will be viewed from long distance by people in the car driving fast then you need a big character size to make it readable. As a rule of tomb you need at least 2 inch of character height for each 100ft of viewing distance to make it readable. For full-color sign with image and video support you may need bigger size to make better impact on viewer.

Pixel Pitch and resolution

Pixel pitch is center to center distance of pixels. The shorter pixel pitch the higher resolution. Viewing distance is the main factor to decide about the pixel pitch. For normal indoor LED sign with image and video support P6 LED modules (6mm pitch) is a standard resolution. However, in some case required high resolution or very close viewing distance P4 LED modules (4mm pitch) is recommended. For outdoor application P8 outdoor led display or P10 outdoor led display (8mm and 10mm pixel pitch) for short viewing distance and P16 modules (16mm pitch) for far viewing distance are mostly used.

Controlling system

Synchronous

This type of LED control card need a computer system to show advertising media on LED display. This type of control card are suitable for application you need to change your display media very often or you need to show lots of media on it (like huge outdoor TVs or huge billboards). There are different synchronous control cards with network, Wi-Fi or GPRS options.

Asynchronous

Unlike the synchronous control cards, asynchronous control cards don’t need any computer to control it. All advertising media is saved in internal memory then control card play it according to the programmed schedule. This type of control card is suitable for any applications doesn’t need every day update like business LED signs, School LED Signs, behind the window LED sign. This type of control card is available with USB, cable, Wi-Fi option etc.

1. What is an LED?

A light emitting diode (LED) is a tiny, electronic semiconductor that converts electric energy into visible light. The chemical compound used within an LED determines its color, brightness and power efficiency. Unlike incandescent lamps, LEDs have no filaments that can burn out or fail.

Surface Mount LEDs

Surface Mount Devices, or SMD for short, refers to the LED lead frame mounting method. LEDs are mounted to the surface of the circuit board. The SMD contains red, green and blue die.

Through-Hole LEDs

Through-hole LEDs are mounted with leads protruding through the circuit board and appear to stand taller. Each LED is a single-color die of either red, green or blue.

LEDs come in two different forms.

Manufacturers use several types of LEDs to construct digital displays. The two most common are Through-Hole LEDs and Surface Mount Device (SMD) LEDs, also known as Surface Mount Technology (SMT). Each type has its respective advantages that make them preferable for different applications.

SMD LEDs

Total light emitted isn't concentrated in a focused area since SMD LEDs do not have directional reflector cups. Instead light disperses evenly across both horizontal and vertical angles, providing wider viewing angles. This makes SMD LEDs an excellent choice for most indoor applications as well as some tighter pitch outdoor applications.

Benefits of SMD:

· Outstanding color blending at short viewing distance

· No color shift at extreme angles

· Wide viewing angle

Through-Hole LEDs

Through-hole LEDs use a reflector cup and an epoxy lens package. This combination as well as the type of die used, plays a role in determining the elliptical viewing cone produced. A through-hole LED's reflector cup focuses the light emitted by the die into a specific viewing area.

Benefits of Through-Hole:

· Optimized for moderate to longer viewing distance

· Louvers deflect sunlight for higher contrast

· Black matte finish reduces reflection

· Brighter than SMD LEDs

2. What is a module?

LED modules are made up of parts that form the building blocks of full color LED displays. Rows of modules line together to arrange the LEDs in different variations depending on the requirements.

3. What is a pixel?

Pixels, short for picture elements, are points of light that illuminate to form visuals. A pixel can be made up of a single LED, multiple LEDs of the same color or multiple LEDs of different colors. They are the smallest elements of the electronics display system that can be individually controlled and turned off or on at various brightness levels.

Pixel pitch and Resolution.

Pixel pitch influences the resolution of the LED display screen. More pixels placed together means higher resolution. High resolution means the image will be clear to viewers even when viewed from close proximity. We will help you to balance the cost as well as the perfect pixel pitch for your installation, to ensure the best fit for your viewing experience as well as your budget.

4. How Does Pixel Pitch Affect Minimum Viewing Distances?

Viewing distances are calculated based on the display type and the distance from the display. Each display will have a minimum and a maximum viewing distance that may vary based on application and intended use.

Selecting the right pixel pitch is important because they influence the resolution of the display screen. High resolution means the image will be clear to viewers even when viewed from close proximity. Whereas lower resolution means large LED display panels may look great from a distance, but if you move closer to them, they will become uncomfortable to view,our website:https://www.chipshow.com.

What Is Pixel Pitch And Screen Resolution?

1. LED Screen Pixel Pitch

The distance between the LED screen diodes determines the resolution of the screen. From the center of each set of red, green, and blue diodes, the distance to the center of the adjacent group is measured. This distance is called the pixel pitch. Each set of diodes together form a pixel – or pixel.

If the LED screen has a pixel pitch of 1 cm, each pixel can have 100 x 100 pixels. Square screen. The resolution on the screen is set to the number of pixels in height and width. If your screen is 6 x 8 meters and the pixel spacing is 1 cm, the resolution is 600 x 800 pixels.

2. Image Resolution

Image resolution is the detail an image holds. The term applies to raster digital images, film images, and other types of images. Higher resolution means more image detail.

Resolution refers to the number of pixels in an image. Resolution is sometimes identified by the width and height of the image as well as the total number of pixels in the image. For example, an image that is 2048 pixels wide and 1536 pixels high (2048 x 1536) contains (multiply) 3,145,728 pixels (or 3.1 Megapixels).

Image resolution can be measured in various ways. Resolution quantifies how close lines can be to each other and still be visibly resolved. Resolution units can be tied to physical sizes , to the overall size of a picture, or to angular subtense.

The measure of how closely lines can be resolved in an image is called spatial resolution, and it depends on properties of the system creating the image, not just the pixel resolution in pixels per inch (ppi). In effect, spatial resolution refers to the number of independent pixel values per unit length. Get more details of small pixel pitch led screen from www.chipshow.com.
