LED Screens Refresh Rate

LED Screens Refresh Rate 

APOLLOMI Reporter

The refresh rate of a LED screen is the number of times in a second that the LED screen hardware draws the data. This is distinct from the measure of frame rate in that the refresh rate for LED screens includes the repeated drawing of identical frames, while frame rate measures how often a video source can feed an entire frame of new data to a display.

On LED screens, increasing the refresh rate decreases flickering, thereby reducing eye strain. However, if a refresh rate is specified that is beyond what is recommended for the LED screen, damage to the display can occur. 

Normally our LED screens  have a refresh rate of over 300Hz, which is more than 5 times the refresh rate of a normal cathode television which is 50Hz (PAL and SECAM) or 60Hz (NTSC). For football stadiums (stadium LED screens and perimeter LED screens) our LED screens can reach a refresh rate of over 1000Hz, which means that they won′t show any flickering when recorded with a video camera and broadcasted live on television

Nowaday LED display are widely used in many occasions, even in sport field. As the perimeter display around the football stadium. This kind of display should have the following features:

1. Easy to use: Fast installation and easy to change the angle when standing there;

2. Protection: As the football game is a kind of fierce competition, a lot of things should be taken into the consideration, for example, protection for the football player and the display.

 use the soft rubber mask and the protection pillow , which can prevent the player from injury,and also avoid destroying the display;

 

3. Good viewing effects: As the display is around the stadium, the audiences should be able to see everywhere clear except facing the back side of the display.  using Dot Matrix technology from us, which has a very good viewing angle and color blending distance;

  The whole perimeter display is very wide but short in height, and normally the display will be splitted into many sections to show the ads or the stadium information. In this way, there is a easy way to control it by one or two computers.If it too long, the signal extender or the fiber will be needed. 

What type of Content should you use for your LEDs?

What type of Content should you use for your LEDs?

One of the most exciting options about using LEDs for advertising is that they are very captivating. In fact, LEDS are commonly preferred because they catch the attention of viewers and basically people from the general public.

LEDs are designed to be very bright and clear which means that they provide an excellent alternative as compared to conventional media like billboards and static posters. Whether it is in front of the lift or waiting for service in a bank, the LED screen serves as a great platform to advertise as people have something to view while waiting.

In using LED screens, advertisers can now provide more innovative and creative ways of reaching their target markets. This means that they are no longer confined to the traditional ways which are not as effective. Through LEDs, they now have more power in generating the type of content which are relevant and definitely more powerful. It must be noted though that using the right content would play a pivotal role in the campaign.

Video content

The most commonly used content in LEDs is videos. Advertisers can now be more adventurous where they can design more video and animation in their otherwise static advertisements. Due to this market opportunity, video production and editing services have become more affordable and available.

In general, you can either develop content which are commercial in nature or merely informational but they must all be equally as captivating and ensures that the audience is interested.

Informational

This type of content is developed for the intention of delivering information to the viewer. As the LED screen is designed to scroll and switch between content, you should design your informational ads to be quick and brief. Unless you own the LED and all the airtime, you should use quick and straight-to-the-point information. If you are the owner of the LED, informational ads can include more text and explanations.

Commercial content

LEDs can be perceived very much like television except that they provide all-round-the-clock advertising potential. This means that through LEDs, you have an especially dedicated channel for advertising. However, as you will be renting the airtime from the service provider, you are limited by the duration of each video. Therefore, you will need to develop the best content for the 10 to 15 seconds as agreed. Such videos must be short and brief while the details of inquiries should be highlighted repeatedly as viewers will want to contact you for more information.

The Sensing Distance of a LED module refers to the device which detects the surrounding and other external factors of the module. This is an important feature of the LED module because it will be activated to ensure better energy efficiency and where necessary ensure that no energy wastage happens.
This feature is actually invoked by a sensor which is usually attached to a LED bulb or a tube. It usually uses Infrared technology to scan its surroundings before changing the lighting or intensity of the light. In most cases, the LED light is programmed to emit lesser light if the surroundings are bright enough. This will allow the premise owner to save on electricity bills and overheads as lesser energy is used.
The term Sensing Distance refers to the 2 points between the sensor and the maximum outreach that the sensor can scan. Hence, it uses a measurement unit of M (meter) and degrees. For instance, the sensing distance of a typical T8 LED Tube is 6-8 meters at 140 degrees. This means that the sensor will automatically scan around its surroundings between 6 to 8 meters and if it finds that the lighting is sufficient, it will then automatically adjust accordingly.
On top of that, the degrees refer to the level of which the sensor will scan. At 140 degrees, the scanning mechanism is not as wide as those that have the capability of scanning up to 360 degrees which will be checking the entire circle of its radius. This means that the more the degrees of the sensing distance is, the more areas the sensor will be able to scan.
Sensing distance is very important for LED tubes especially when they are deployed in areas which are hard to reach and where there is a need to automatically manage the devices.

One of the amazing factors about LED is that they are able to produce a variety of colors which are bright and clear. Unlike conventional lighting devices, LED is able to mix and combine various shades of colors as they have a rich source of RGB (Red, Green and Blue) elements.

Naturally, the more combinations are available, the more colors and shades will be available. This means that using more RGB bulbs will allow the particular LED devices to produce more colors and surely more variations of a specific hue which means that the device can be used in larger screens and display panels.

LED source is commonly used to depict how rich the colors of a specific LED device will be. This type of specification is commonly depicted in terms of R, G and B. They are used in most LED modules while there are some which are installed onto LED strips that can produce many color combinations.

The LED Source information comes in many forms which defines the number of bulbs available in a specific module. At R4, G4, B4, it means that each unit is made up of 4 red bulbs, 4 green and 4 blue bulbs respectively.

The intensity of a specific color depends fully on how many bulbs are equipped into each unit. There are certain LED modules which come with larger components in which they are depicted at R12, G 12 and B12. This is popularly used in larger LED components and those that are intended for larger spaces for display. In this context, it must be noted that the figure 12 depicts that there are 12 Red, Green and Blue bulbs respectively which means that this particular module will be able to produce richer colors and in more variations than those that have lesser colored bulbs.
