Lộng lẫy hơn, sống động hơn, nổi bật hơn... Hiện nay, các thiết bị giải trí và máy chơi game arcade đã có sự tiến hóa đáng kể so với trước đây.
Why have they been able to evolve in this way? Of course, the biggest reason is user demand. Product planning advanced in response to user feedback. However, that's not the only reason. There are also technical reasons, namely the increase in brightness and reduction in the cost of light-emitting diodes (LEDs). With high-brightness LEDs, fewer LEDs can provide for a brighter display. Additionally, the cost reduction has allowed for the use of more LEDs. Thus, the display functions of amusement devices and arcade game machines have significantly evolved due to the synergy of increased brightness and reduced cost of LEDs.

Môi trường tiếng ồn kém
Việc lắp đặt nhiều đèn bet88 kèo nhà cái trong các thiết bị giải trí và máy chơi game arcade mang lại hiệu ứng hiển thị lộng lẫy hơn, sống động hơn và nổi bật hơn. Lợi ích này rất có ý nghĩa đối với các nhà sản xuất thiết bị.
However, the design of the bet88 kèo nhà cái driver circuit that drives the LEDs becomes more challenging. This is because the interior of amusement machines and arcade game machines generally have a poor noise environment. These devices contain various high-performance LSIs and high-speed interfaces, which emit high levels of electromagnetic interference (EMI), or noise. Additionally, noise can be generated from contact with medals and other objects. When such noise infiltrates the bet88 kèo nhà cái driver circuit, it can cause incorrect bet88 kèo nhà cái lighting, resulting in a distorted display that appears unnatural to users.
Why can this noise cause incorrect bet88 kèo nhà cái lighting? Let us take a deeper dive into this topic. Generally, in amusement devices and arcade game machines, multiple bet88 kèo nhà cái driver ICs are used to drive numerous LEDs. However, there is only one CPU controlling the display. Typically, some form of interface technology is used to connect the CPU with multiple bet88 kèo nhà cái driver ICs.
Candidates for this interface technology include the I2C interface method, shift register method, and 3-wire serial interface (2-wire serial interface), with the 3-wire serial interface (2-wire serial interface) being commonly used. The 3-wire interface uses three signal lines to send data (SDA) signals, clock (SCL) signals, and slave select signals (Fig. 1). The 2-wire interface transmits data (SDA) signals and clock (SCL) signals using two signal lines.
When noise infiltrates these serial interfaces, it adversely affects the signals propagating through them. Specifically, the signal waveform becomes distorted, preventing proper signal transmission. There are various paths through which noise can infiltrate. In some cases, noise generated very close by directly enters the serial interface, negatively affecting the signal. In other cases, noise enters the ground, causing the ground potential to fluctuate, which then adversely affects the signals propagating through the serial interface.
In either case, the waveform of the signal propagating through the serial interface becomes severely distorted, preventing correct signal transmission. As a result, LEDs may fail to light up when needed or may light up when not needed.

IC điều khiển bet88 kèo nhà cái có một tính năng quan trọng khác đó là tính linh hoạt thiết kế rất cao trong phương pháp kết nối IC điều khiển LED.
As mentioned earlier, amusement devices and arcade game machines require the driving of numerous LEDs, so multiple bet88 kèo nhà cái driver ICs are used. There is only one CPU to control the display. Therefore, the CPU and multiple bet88 kèo nhà cái driver ICs must be connected. There are two connection methods: cascade and multi-drop.

LVDS
THine Electronics' bet88 kèo nhà cái driver ICs support both the cascade and multi-drop methods (Fig. 5). Moreover, the methods can be mixed together. The cascade and multi-drop methods have their own advantages and disadvantages. The cascade method has a simple structure but is difficult to meander or branch off significantly. The multi-drop method can be branched easily, but it requires more wiring, and the mounting area can become relatively large.

Conventionally, when a 2-wire or 3-wire serial interface is adopted, as the connection distance increases, the distortion of the signal waveform and the decrease in amplitude increase, making it more likely that data/clock signals cannot be transmitted correctly, therefore, it was necessary to insert a TTL buffer IC at the entrance of the printed circuit board.
