SMD LED displays compared to traditional in-line, has many advantages: First, a wide viewing angle. Outdoor SMD full color LED screen not only has more than 110 degrees to 140 degrees wide viewing angle in the horizontal direction than in the vertical direction also has a wide viewing angle of 110 degrees, which is particularly advantageous in some applications, outdoor venues, such as building advertising screens, hanging altitude outdoor LED display requires a broader perspective in order to show better advertising results; second, with a good light. Surface-mount technology uses full-color SMD triple structure because of the design structure, namely red, green, blue three chips among all packaged in a bracket cups, lamp beads to form a patch, so red at different angles, green and blue brightness matching consistency highly consistent, which makes outdoor full color SMD LED display at any angle to match the brightness of consistency is very good owl DJ sets, to achieve better color fidelity effect; the third, a good mix of light . SMD technology design structure for triple instead of a group of in-line needs to have red, green, blue three discrete oval LED, SMD module therefore mixed light better than in-line oval LED modules, especially suitable for close watch; fourth, high contrast. Due to the design of triple structure, small size, full-color SMD small emitting area, wide black area, greatly improving the contrast of full-color LED display; fifth, automated production. SMD LED automatic placement machine can be used to automate patch, high production efficiency. Outdoor SMD LED display module circuit design enables light board and driver board combo owl DJ booth installation, reduced costs, improved reliability, enhanced productivity. In addition, automated SMD chip production but also improve the vertical accuracy of the circuit board, to overcome the in-line oval LED vertical accuracy problems in the circuit board, thus ensuring better optical effect; sixth pin owl DJ sets light weight box. Aluminum alloy box structure design is very light; and not easily deformed appearance assembled easily and smooth. Suitable for leasing companies, car screen, mobile media use; pillar or wall mount installation even reduce the pressure on the support structure of the body of the screen. In the electronic apparatus, the ground is an important method of controlling interference. Such as proper grounding and shielding can be used in combination, can solve most of the interference problem. Electronic devices generally have systematically ground structure, chassis ground (the shield), digital ground (logically) and analog land. In ground design should pay attention to the following points: 1, the correct choice of single-point and multi-point grounding grounding in the low-frequency circuit, the operating frequency of the signal is less than 1MHz, the smaller the impact it's wiring inductance and between devices, and the formation of ground circuit circulation greater impact on interference, and thus should adopt a little ground. When the signal is greater than the operating frequency of 10MHz, ground impedance becomes very large, and you should try to reduce the ground impedance should be used near multi-point grounding. When the operating frequency 1 ~ 10MHz, if a little ground, its length should not exceed ground wave [url =] B [/ url] length of 1/20, or should be multi-point grounding method. 2, digital circuits and analog circuits separate board of both high-speed logic circuit, there are linear circuits, should be separated as much as possible to make them, but do not be confused between the two ground is connected to the power supply terminal ground respectively. To try to increase the contact area of ??linear circuits. 3, be bold if the ground wire grounding line is very thin, the ground potential varies with the current changes, resulting in an electronic device timing signal level instability, anti-noise performance deterioration. Therefore, the ground wire should be bold owl DJ sets, making it through three located on the printed circuit board to allow current. When, if possible, should be greater than the width of the grounding wire 3mm. 4, the printed circuit board ground line constitute ground system closed loop design only by the digital circuit, the ground wire made of a closed loop can significantly improve the anti-noise capacity. The reason is that: the printed circuit board has a lot of integrated circuit components, especially in case of multi-component power consumption when, due to the grounding line thickness limits, will have a greater potential difference on the ground junction, causing decreased noise immunity , if the ground structure into a loop, it will reduce the potential difference and improve the noise immunity of electronic equipment.
