How to correctly choose display for your advertising ?
The most important factors influencing the correct selection of LEDs are the distance from which the LED display is viewed and the exposure of the LED display to daylight or other bright light sources.
If you look at the LED display under a strong daylight or in indoors with strong ambient light, it is recommended that you take off the display with higher light (≥ 5,500nits) to make the display more visible (situation 1, situation 2).
For a clear view of the image viewed from a greater distance, (Situation 1) it is recommended to select a display with a larger LED distance, ie a smaller resolution image (≥ P3.9mm). If the LED display is viewed at a smaller distance, (Situation 2), we recommend selecting a display with a smaller dimmable LED, ie a larger image resolution (≤ P3.9mm).
If you use LEDs in low-lighted areas or outside the building during the night or during the day, and in less lighted areas, it is recommended to select LED displays with standard lighting (≤ 3.500nits).
P (pixel pitch)
Distance from the center of the LED to the center of the next adjacent LED display. The term is used for image density (image resolution).
The related term is “Line Pitch” which defines the distance between the pixels of the pixels.
Nits (cd / m2)
A lighting unit is used to define the brightness of the light emitted by the LED display or any other similar light source.
Display resolution
The display resolution or display modes of a digital television, computer monitor or display device is the number of distinct pixels in each dimension that can be displayed. It can be an ambiguous term especially as the displayed resolution is controlled by different factors in cathode ray tube (CRT) displays, flat-panel displays (including liquid-crystal displays) and projection displays using fixed picture-element (pixel) arrays.
Refresh rate
The refresh rate is the number of times in a second that a display hardware updates its buffer. This is distinct from the measure of frame rate. The refresh rate 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.
For example, most movie projectors advance from one frame to the next one 24 times each second. But each frame is illuminated two or three times before the next frame is projected using a shutter in front of its lamp. As a result, the movie projector runs at 24 frames per second, but has a 48 or 72 Hz refresh rate.
On cathode ray tube (CRT) displays, 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 display, damage to the display can occur.
For computer programs or telemetry, the term is also applied to how frequently a datum is updated with a new external value from another source (for example; a shared public spreadsheet or hardware feed).
By properly selecting the LED/LCD display, you will save both on project cost and on electricity consumption. Stronger lighting and higher image resolution of the LED/LCD display also result in more power consumption.
Keep in mind that the LED/LCD display does not work continuously fully loaded *, but with approximately 35% of the full capacity itself and from the nominal consumption of the EL. Energy.
“A fully loaded display would constantly display a full-blown white image in the brightest mode of light.”
In any case, you can rely on our experts who will rightly choose a project that offers optimal solutions with minimal accrued costs.
