P4mm UHD Small Pixel Pitch Indoor LED Display

Small pixel pitch LED Display is also called fine pixel pitch LED display, narrow pixel pitch LED display which has a fast developing market due to the advantages of seamless design, higher contrast, higher brightness, higher gray grade fine pitch, etc..

Small pixel pitch LED Display has elevated the industry standard for image and video quality. It provides new opportunities for content previously restricted to LCD video wall. The smaller and tighter pixel spacing create a more detailed and crisp appearance, making these products ideal if you want to add an element of luxury and high quality to your location. It delivers true-to-source color reproductions and pristine image quality with smaller available physical space at a closer viewing distance.

Even a relatively small size, it can have an extremely high resolution. It produces more heat than traditional pixel pitches because more LEDs are concentrated together in the product design. Its performance depends on managing this heat to keep color reproduction and brightness at peak performance. Our small pixel pitch LED Display effortlessly manage heat, with half of the power consumption of an industry standard solution and cool operation even at full brightness.

Small pixel pitch LED display mainly refers to the models which the pixel pitch <= 2.5mm, such as P2.5mm, P2.0mm, P1.923mm, P1.875mm, P1.667mm, P1.562mm, P1.25mm, P1.2mm, P1.0mm, P0.88mm, P0.75mm etc. It needs high precision SMT machine to produce since common SMT machine can just produce the pixel pitch which is bigger than 2.5mm.  Our factory have the industry's highest precision super high-speed SMT machine from Japan Yamaha which is equipped for small pixel pitch LED display production. Its market is increasing more than 70% in the last 2 years and is still increasing much faster than the conventional products.

One of the most asked questions is how to calculate the maximal power consumption of a LED display. Well first of all, you should know the input current and the voltage of the LEDs. Theoretically, in a labratory environment the greatest input current of the LEDs is 20mA, and the voltage for the LEDs is 5V. But in reality, the current of the LEDs can't reach 20mA. So the power consumption of a LED is 20mA x 5V = 0.1W. So it is very simple how to calculate the power consumption of one LED.

Pixel Configuration of LED Displays

And secondly, what you should know is the pixel configuration and the resolution per square meter. When you get this data you will know how many LEDs are available on the LED Display. For example, let's take a LED Display with a pixel pitch of P16mm, the pixel configuration is 2R1G1B, which means that each pixel consists of 2 red LED's, 1 green LED and 1 blue LED. So this means that every pixel has 4 LED's. And the resolution per square meter of pitch 16mm LED Display is 3906 pixels, which means there are totally 3906 pixels in one square meter. According to the previous data the calculation will be as folows: 4 x 3906 = 15,624 total LED's per square meter.

Maximal Power Consumption

There are two types of driving methods for LED Display s, which is the constant static driving method and the scan driving method. First let's explain how to calculate the maximal power consumption and average power consumption of a pitch 16mm LED Display using constant static current driving.

Constant Static Current Driving Method

The maximal power consumption of a pitch 16mm LED Display is 15624 x 0.1W = 1.56Kw pero square meter. The average power consumption is 1.56Kw / 2 = 780W. This calculation way is for static constant current driving LED Displays.

Scan Driving Method

For scan driving LED Display, you must notice that it has a 1/4 driving, 1/8 driving or 1/2 driving. Taking a pitch 6mm indoor LED Display as an example, the usual driving method is 1/8, so if you calculate according to above way, the maximal power consumption of a pitch 6mm indoor LED Display will be extremely high and gives us more than 8Kw per square meter. But in reality it is not correct, the reason is that you need to make the total calculation result divided by 8 because the driving method is 1 over 8 (1/8), and like that you get a maximal power consumption of 1.1Kw per square meter.

The Relationship between Brightness and Viewing Angle

What is the difference between brightness and viewing angle. Well depending on the environment (indoor or outdoor) where a LED display is installed, the requested brightness of a LED display is different according to the environmental contrast ratio.

Difference between Indoor LED display and Outdoor LED display Brightness and Viewing Angle

Indoor LED display request a lower brightness but request a high viewing angle. On the other hand outdoor LED display request a higher brightness, and also a much better better grey grade. Therefore the outdoor LED display' viewing angle request is not as high as an indoor LED display, generally between ± 35--± 50 degrees.

Relationship between Brightness and Viewing Angle

If the viewing angle becomes lower, the  brightness will be higher, or vice versa. If the contrast ratio between brightness and environmental brightness is higher, the showing performance will be more colorful. However, if the brightness is too high, it is bad for the human eye, and much more power consumption will be wasted. Also much more heat will be produced, and then the temperature becomes much higher. For that the led chip's brightness decreases much faster, and of course, its lifespan will become shorter.
