When voltage is applied to specific segments of the digital tube, these specific segments will light up to form the words we see with our eyes. For example, to display the word "2", a should be bright, b should be bright, g should be bright, e should be bright, d should be bright, f should be dark, c should be dark, and dp should be dark. LED digital tubes are divided into normal brightness and super brightness, and also have different sizes such as 0.5 inch and 1 inch. The display strokes of small-sized digital tubes are often composed of one light-emitting diode, while large-sized digital tubes are composed of two or more light-emitting diodes. Under normal circumstances, the tube voltage drop of a single light-emitting diode is about 1.8V, and the current does not exceed 30mA. The anode of the light-emitting diode is connected together to the positive pole of the power supply, which is called a common anode digital tube, and the cathode of the light-emitting diode is connected together to the negative pole of the power supply, which is called a common cathode digital tube. The numbers and characters displayed by commonly used LED digital tubes are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F.
1.LED digital tube uses light-emitting diode as the light-emitting unit, and the colors include single red, yellow, blue, green, white, yellow-green and other effects. Monochrome and segmented full-color tubes can be used to illuminate the outlines of buildings, roads, and riverbanks. LED digital tubes can be evenly arranged to form a large display area, which can display patterns and texts, and can play video files of different formats. Download flash, animation, text and other files from the computer, or use animation design software to design personalized animations, and play various dynamic color-changing graphic effects.
2. It can be placed on the PCB circuit board in a straight line in the order of red, green and blue, and controlled by a dedicated driver chip to form endless colors and graphics. The shell is made of flame-retardant PC plastic, which has high strength, impact resistance, aging resistance, UV protection, dustproof and moisture-proof. LED digital tubes have the advantages of low power consumption, no heat, impact resistance, and long life. With the controller, it can achieve effects such as flowing water, gradual change, jump change, and chasing. If it is used in large-scale projects, it can also display patterns and animation videos by connecting to a computer synchronous controller. The equivalent LED digital full-color lamp can form an analog LED display screen. The analog display screen can provide various full-color effects and dynamic display image characters. It can be controlled offline or connected to a computer for synchronous control, and can display a variety of full-color dynamic effects. The control system is edited with special lighting programming software. The digital tube control pattern can be easily changed. You only need to copy the edited pattern format file into the CF card. The digital tube controller can be controlled individually or multiple units can be controlled online. The digital tube installation arrangement is arbitrary, which is suitable for various complex engineering needs. The digital tube, controller and power supply are connected with standard male and female plugs, which is convenient and fast, and has a unique appearance design and a brand-new outdoor waterproof structure.
