What is Nit brightness?
How to measure NIT brightness?
How to choose the right NIT brightness
Nit brightness (also known as Nit brightness or Candela brightness) is a unit used to measure the brightness of displays, televisions, projectors, and other devices. It represents the intensity of light emitted or reflected in an area per square meter. Nit brightness is often used to describe the brightness level of the display device, and is also an important indicator to evaluate the visibility and display effect of the display screen under various environmental conditions.
The higher the nit brightness value, the brighter the display. Common TVS and monitors typically have a brightness range of several hundred to thousands of nits. Higher brightness often provides sharper, more vivid, and more attractive image effects, especially in bright environments or when viewing from a distance.
Measuring Nit brightness requires the use of a professional measuring instrument, such as a photometer or colorimeter. These instruments can accurately measure the intensity of the light emitted by the display device and display it in nits.
The following are the general measurement steps:
Prepare the measuring instrument: Ensure that the photometer or colorimeter used meets the requirements and is calibrated.
Set display device: Set the display device to the brightness level you want to measure. You can adjust the brightness Settings or the display mode to achieve the desired brightness.
Position the measuring instrument: Position the photometer or colorimeter perpendicular to the surface of the display to ensure that it measures the light source of the display.
Make a measurement: Press the corresponding button on the measuring instrument or trigger the measurement command to start measuring the intensity of the light emitted by the display device.
Record measurement results: According to the display of the measuring instrument, record the measured nIT brightness value.
Ambient brightness: If you are using your display device in a brighter environment, such as outdoors or indoors with strong light, you may need a higher nIT brightness to ensure that the image is clearly visible. In general, a higher brightness range (e.g. 500 nits or higher) is suitable for bright environments, while a lower brightness level may also be sufficient in darker environments.
Application requirements: Different applications may have different brightness requirements. For example, professional graphic design, film and television production, or gaming may require higher brightness to display more accurate and vibrant colors. Document processing or general browsing in an office environment may not require as much brightness.
Prolonged use and eye comfort: Excessive brightness may cause discomfort to the eyes, especially during prolonged use. Depending on your personal preference and comfort, you can choose the brightness level that suits you.
Device specifications and quality: Different display devices may have different brightness ranges and performance levels. You can refer to the device's specification sheet and product description to understand its brightness characteristics and choose the device that suits your needs. Do you know what the supporting equipment of the led display is?
Taking the above factors into consideration, you can choose the appropriate Nite brightness level according to your use scenario and personal preference. It is best to observe and adjust the brightness of the display device before actual use to find the best viewing experience.
