How Well Do You Know The LED Display Parameters?
LED displays are becoming more and more ubiquitous, from TV screens to digital billboards and electronic scoreboards during sporting events. But few people understand the inner workings of LED displays or what each parameter means. This blog post will guide you through the world of parameters related to LED displays and give you all the info you need.
Pixel Pitch
The most critical parameter of an LED display is pixel pitch. This measurement refers to how far apart two pixels are from each other and is usually measured in millimetres. A lower number indicates higher resolution; more detail and better quality images result from a smaller pixel pitch.
Brightness
LED display brightness is measured in nits. This indicates how much light is emitted from the device, with brighter displays appearing brighter if they have a higher number of nits. Outdoor displays require bright sunlight to be visible so brightness plays an important role.
Refresh Rate
The refresh rate refers to the frequency at which an LED display's image is refreshed. Higher refresh rates enable smoother, more detailed motion. Frequency is measured in Hertz (Hz). LED displays typically offer refresh rates between 60Hz and 120Hz.
Contrast Ratio
The LED display's contrast ratio measures the difference in brightness and darkness between images. A higher contrast ratio will produce better color reproduction and finer detail, typically measured as 1000:1.
Viewing Angle
The viewing angle refers to the maximum angle from which an LED display image can be viewed without causing any quality loss. It's the maximum angle at which LEDs can be viewed without significant degradation in quality, making them more versatile. Viewing angles are typically measured in degrees.
Color Temperature
The LED display's color temperature measures the intensity of light emitted. This value is typically expressed in Kelvin (K), with higher numbers indicating cooler (more blueish) hue and lower ones denoting warmer (more yellow) tones. When displaying colors accurately in photography or printing, color temperature must be taken into account; otherwise, inaccurate hues could result.
Energy Consumption
LED displays consume a considerable amount of power, so it's essential to take into account their power consumption when making decisions about which light source is suitable. Power consumption is usually measured in watts (W), though actual figures may differ depending on the size of the display.
Conclusion
Before making your purchase decision, it's essential to understand the specifications of an LED display. Factors like pixel pitch, brightness and refresh rate, contrast ratio, viewing angle, color temperatures, power consumption - these all matter when looking for the ideal display whether it be outdoor advertisement screens or high quality diodes. With these parameters in mind you can make an informed decision whether you need something outdoor advertising-ready or high quality diodes.
