1. On the color gamutOLED displays can display endless colors, and are not affected by the backlight. Pixels are very advantageous when displaying a completely black screen. Currently, the color gamut of LCD displays is between 72% and 92%. , while the color gamut of the LED display is above 118%.2. In terms of priceLED displays of the same size are more than twice as expensive as LCD displays, and OLED displays are even more expensive.3. In terms of technology maturityBecause LCD display is a traditional display, it is much better than OLED and LED in terms of technology maturity, such as display response speed, OLED and LED are far behind LCD displays.4. In terms of the angle of the displayOLED displays are much better than LED displays and LCD displays. The specific performance is that the viewing angle of LCD displays is very small, while LED displays are unsatisfactory in terms of layering and dynamic performance. In addition, the sense of depth of LED displays is not good enough. With the development of technology, liquid crystal technology is also constantly improving, and people's demand for various displays is also constantly increasing. Perhaps in the future, liquid crystal technology will develop to a new height, and there may be a new kind of display that can replace liquid crystal technology. new technology.

LED display (LED display) is a flat-panel display, which is composed of small LED module panels, and is used to display various information such as text, images, videos, and video signals.An OLED display is a display made of organic light-emitting diodes. Since it also has self-luminous organic electroluminescent diodes, no backlight is required, high contrast, thin thickness, wide viewing angle, fast response speed, can be used for flexible panels, wide operating temperature range, simple structure and manufacturing process, etc. , is considered to be the next-generation flat-panel display emerging application technology.The prospect of China's OLED industry is very broad, and companies in the industry are also working hard to accumulate development experience. However, factors such as weak upstream links in the domestic industrial chain and lack of supporting capabilities in the industry have created relatively large development obstacles for the majority of manufacturers.LCD display, also known as liquid crystal display, is a flat and ultra-thin display device, which consists of a certain number of color or black and white pixels, placed in front of the light source or reflective surface. Liquid crystal displays consume very little power, making them favored by engineers for electronic devices that run on batteries. Its main principle is to stimulate liquid crystal molecules with current to generate points, lines, and surfaces to form a picture with the back lamp tube.

IoT applications need to consider many factors, such as node cost, network cost, battery life, data transfer rate (throughput), latency, mobility, network coverage, deployment type, etc. It can be said that no one technology can meet all the needs of IoT. NB-IoT and LoRa have different technical and commercial characteristics, so there will be differences in application scenarios. The difference between the two will be explained here, and the applicable application scenarios for each will be explained.Frequency Bands, Quality of Service, and Cost LoRa work in the unlicensed frequency band below 1GHz, so there is no need to pay extra for the application. NB-IoT and cellular communications use licensed frequency bands below 1GHz. The frequency band between 500MHz and 1GHz is the best choice for long-distance communication because the actual size and efficiency of the antenna are quite advantageous.LoRaWAN uses free unlicensed frequency bands and is an asynchronous communication protocol, which is the best choice for battery power and low cost. LoRa and LoRaWAN protocols have unique characteristics in handling interference, network overlap, scalability, etc., but they cannot provide the same quality of service (QoS) as cellular protocols. It is reported that the bidding price of the authorized Sub-GHz frequency band exceeds US$500 million per MHz. Cellular networks and NB-IoT cannot provide the same battery life as LoRa due to quality of service (QoS) considerations. Due to QoS and high frequency band usage fees, cellular networks, and NB-IoT are recommended for applications that need to ensure QoS, and LoRa is a good choice if low cost and a large number of connections are the first choice, as shown in the figure below.
