Introduction
LED displays are a huge feast to eyes if the image displayed on the screen is of the best quality. You may have noticed that you can view the image just fine when you are viewing it from the front but when you are viewing your TV from the side, the image may appear negative. This is caused by the viewing angle of your led display.
In this article, we’ll be explaining what viewing angle is, why it is important for LED screens and how you can choose the ideal angle for your LED display.
- What is a viewing angle?
Viewing angles are the angles at which the image or content displayed on the screen can be viewed properly. To explain it in simpler words, it is a position of the led display at which the viewers can view the image in the best form. Reduction in viewing angle only allows viewing the adequate quality image in front of the screen.
The size of your led display and the type of leds used in the display has a huge impact on the viewing angle of your screen. Especially for commercial and professional use, you should always consider the viewing angle of your led display to ensure that the audience can view the display properly depending on their placement. For this reason, before getting an LED display you should know where you are going to place it. Consider the placement of the led display, from where the audience will be viewing it and what size you need.
For events and applications that require LED displays with high viewing angles, you should always choose LED displays with full viewing angles or big viewing angles. Outdoor LED displays for advertisement may need wider viewing angles since wide viewing perspectives are important in such cases. Same goes when you have a large TV lounge and have more TV viewers.
- Why is a viewing angle important
Viewing angles has a huge impact on the kind of image you are going to view on your screen. The quality of the image that you are seeing on the screen depends on the distance you are standing at, the direction you are viewing it from and the angle you are viewing it from. The viewing angles of screens are measured both vertically and horizontally to find out at what range of angles a display can be viewed without seeing a negative image.
If you view the image from an angle wider than the viewing angle of the display, you’ll not be able to experience the best visuals. LED displays are supposed to be viewed by the audience and provide the audience a good viewing experience. If the image displayed on the screen cannot be viewed by the audience properly, then there’s no point in LED displays. For this reason, it is important to ensure that the LED display has an appropriate viewing angle needed for the usage and location of the LED display.
Before getting an LED display, you should always consider the location and purpose of the LED display to ensure that all of the audience enjoys the best view of the content displayed on the screen.
- What is a good viewing angle for a led display?
For household televisions, the best viewing angle is from 0 to 15 degrees. This viewing angle makes the television viewing experience the most comfortable. With this viewing angle, you can comfortably watch tv and have the best visual experience. This is also the reason why sitting in the front of the cinema is uncomfortable since the viewing angle is not suitable.
However, this is only the case when you are watching TV in the lounge on a couch. If you are installing your TV in your bedroom and are going to watch it while lying down on your bed, then you’ll have to install it higher up. You should install it over 100cm. It is recommended that it should be installed with a slope of 95 to 100 degrees.
For outdoor advertising LEDs, a wider angle is preferred. Before installing any LED display, you should always consider all the different aspects of it and make sure to get the feel of viewing from different angles to make sure the LED display can be viewed comfortably from the place you want to view it from. This allows the audience to have the best viewing experience when viewing the content.
- How to improve viewing angle of a an led display
Before you invest in an LED display, use a piece of cardboard the size of the LED you wanna buy and try to consider it as a display. Also, efficiency of the led display improves the contrast so adjust the polarizer from 98% to 99.9%. With backlights, transmissive polarizer works better and with ambient light, reflective polarizer works better.
You should also always use the highest quality orientation layer on your display. A high-quality rubbing fiber, rubbing equipment and high quality polyimide will help you. You should also test out different display modes on your display. For a wide sitting arrangement, you should consider getting an IPS panel or an OLED. However, if you do own a VA panel already then you should try to sit far back when the image doesn’t look satisfactory.
Some panels work better in terms of viewing angle as compared to other panels. This is why, choose the one that you think will suit you better. You should also consult your lead display provider since they will be able to guide you better with their expertise and you won’t have to face the risk of getting an unsatisfying product.
- How to estimate the viewing distance in led displays?
Like viewing angle, viewing distance also plays a huge role in what kind of image you view depending on where you are viewing it from. This is why it is highly important to estimate the viewing distance especially when you are installing an outdoor LED display. For outdoor advertising displays, you would want your audience to be able to view the content regardless of where they are standing.
Small pitches allow better quality images in indoor or interactive led displays. So, in case of indoor led displays, you should always opt for LED displays that have smaller pixel pitch. However, outdoor led displays that are hung in one area can get away with higher pixel pitches. With lower pixel pitch, you will be able to achieve a smooth picture and even if a person stands close to the screen, they’ll be able to experience the high-quality visuals.
On the other hand, with higher pixel pitches, if a person stands close to it, the picture will appear pixelated. For this reason, hgh pixel pitches are appropriate for large distance viewing and small pitches are appropriate for indoor separation with close viewing distance.
- When does the viewing angle of the led display matter?
Though viewing angle does matter for non-commercial led displays as well but it is more important for commercial and corporate purposes. For instance, in the case of outdoor advertising LED displays, you would want your ad to be visible to a large number of people regardless of where they are standing. For this reason, you’d be opting for options like wide angle LED displays etc to make sure that people are able to view the display even if they are not standing right in front of the display.
Similarly, in larger conferences or events with large audiences, a led display should be able to display the high-quality image even to those who are not sitting in front. This makes viewing angle highly important to consider in such circumstances.
However, viewing angles also matter when you are installing a led display at home. For example, if you are installing a led display in your bedroom then you’ll have to install it differently than you would if you would be installing in your lounge. Wider viewing angles allow you to view the image accurately regardless of where you sit.
Conclusion
As mentioned in this article, viewing angles are highly important when it comes to investing in a led display. With LED displays, you don’t want to risk getting a product that does not fit your needs. Pay attention to what purpose you are going to use it for, where you are going to install it and how many people will be watching it. Also consult with your led display provider since they will be able to guide you better with their expertise.
Take a walk around the display. Narrow viewing angles would only allow you to view the image accurately from front. On the other hand, with wide viewing angles, you can view the image accurately from multiple angles. If you are getting the display for yourself only then narrow viewing angles might be enough but with wider seating arrangement of audience you may need wider viewing angles.
