Светодиодные дисплеи используются практически для любых целей в сегодняшнем оцифрованный мир. Просто глядя на мир вокруг становится очевидным, насколько далеко светодиодные технологии пришли. Светодиодные дисплеи встречаются в домах, на полах, потолках, обернутые вокруг колонн, подпираемые на стекле и даже покрывающие весь фасад больших зданий. Они имеют невидимые светодиодные дисплеи, гибкие светодиодные дисплеи, светодиодные дисплеи, которые могут быть объединены, как головоломки, чтобы взять на себя точную форму и размер поверхности установки и многое другое.

По мере того как технология LED выдвигает яркость представленных электронных дисплеев увеличивала экспоненциально пока их размер получал более малый, более тонкий, более гибкий, универсальный, робастный и легко настраиваемый. Тем не менее, качество светодиодных дисплеев всегда считалось приоритетом, а также продолжает улучшаться. Это одна из основных причин, почему светодиодные дисплеи стали тенденцией и взяли весь мир цифровых дисплеев штурмом. По данным светодиодных поставщиков решений, таких как Street Communication, светодиодные видеодисплеи используются как для домашних, так и для коммерческих целей просто потому, что они потребляют меньше энергии, дольше и предлагают более высокое качество изображения. Технический мастер, который был прикреплен к Street Communication также утверждает, что качество светодиодных дисплеев не может быть отнесено только к его размеру пикселей точка (пиксель шаг), как Есть много других факторов, начиная от типов светодиодных огней, используемых, ICs, драйвер дисплея и режимы сканирования. Учитывая тот факт, что размеры пикселей (которые указывают на расстояние между светодиодами в миллиметрах); в этой статье особое внимание будет уделяться режиму сканирования, который также оказывает значительное влияние на качество светодиодных дисплеев.

Quality Matters: A Brief on LED Display Quality

The quality of LED displays is dependent on a variety of elements or rather specifications which range from perceived image performance, reliability, pixel pitch size, LED display flickering and many others which makes it hard to know the prices ratios of these specifications or how they are calculated users rummage through specification sheets or the user guides that manufacturers include in the product.

For instance, fine pitch/ narrow pixel pitch size has hit the market for nearly a decade and quality ratings are also afforded for the life cycle of LED displays that in the current times are upwards of 100,000 hours or about 11 years. Hence three primary elements are considered when seeking to choose LED displays as indicated by the spokesperson from Street Communication which is as follows:

Image Performance is the key factor and involves assessing the overall performance of LEDs. Consistency, stability, and reliability are gauged based on the fact that they are critical towards image performance and as well as the long life. The size of the LED also governs the pitch of the pixels, which is the determining factor for resolution and thus image quality.

The Drive Electronics that make up a big part of the entire system is only second to the LEDs themselves. This is because the circuitry plays a vital role in the reliability, power, and more importantly in this case – image fidelity.

The Mechanical Design which is primarily related to alignment and mounting depth is also a vital factor towards creating a seamless image projection. Ensuring that seams are aligned perfectly to not form black or white lines is also important as the human eye would discern these lines quickly which makes viewing uncomfortable.

Scan Modes for LED Displays

Another often mentioned technical term is “scan mode”, otherwise also referred to as “driving method “which can be confusing to both end-users and technical personal. However according to the ‘tech commandos’ at Street Communication ‘scan mode’ is not hard to understand at all. A simple example that could be used to explain the scan mode for 1/4 driving led display could be imagined that at a given moment, that only 1/4 of the LEDs is being driven by the IC. Although this may be quite the challenge to discern with the naked eye, professional cameras set at high shutter speeds can capture it. Scan modes exist in ratios of 1/4, 1/8, 1/16 which is acceptable since most times we do not require high brightness or high refresh rate frequencies. This is also in line with the need to reduce the level of power consumption and hence the cost. The scan mode, therefore, can be stated as the element that determines the ratio of the number of lines of LEDs that are driven simultaneously to the total number of lines of each module. The scan mode of a LED wall screen can be an important parameter to choose between several tiles as it impacts three critical parameters of the LED screens which are the light perception, the electric consumption and the refresh rate which. When the refresh rates are higher it compensates for a low scan ratio. There are two primary modes of scanning which are static scanning and dynamic scan modes for video displays.

Dynamic Scan Mode

Dynamic scan mode involves the implementation of a ‘point to column control’ system for which a dynamic scan control circuit is needed. In general, the cost for dynamic scan modes are lower compared to static scan modes, but as can be expected offers a less effective video display brightness and higher loss from the output between the pixels.

Static Scan Mode

Static scan modes, on the other hand, involve the implementation of the output driver between the pixels “point” of control which does not require it to have a control circuit. However, the cost for static scan modes are significantly higher compared to dynamic scan modes and as can be expected the video display quality is good and stable apart from the fact that the loss in brightness and stability is significantly smaller.


The scan mode is a critical aspect or element for consideration based on the fact that it impacts the quality of the video display, LED display flickering rate, refresh rate and as well as the number of frames per second. The number of frames per second is in turn vital towards the ‘smoothness’ of image projections for LED video display systems.
