Fully surpass the Korean factory! China's LCD production capacity is 2018

As we all know, BOE and Tianma Microelectronics are all making AMOLED panels. The corresponding 6-generation production line has already been put into production. Although Samsung is currently in the sector with absolute power, many domestic panel makers have also shown a trend of catching up.
Although AMOLED panels are still lagging behind, Chinese panel makers on LCD panels can already appeal to South Korean manufacturers. According to a report released by IHS Markit, in 2017, shipments of large-size LCDs with 32-inch or larger sizes to Chinese manufacturers reached 330,000. The film, an increase of 33% over the same period last year, is still in rapid growth.
In the end, China will become the world's largest LCD panel production base in 2018. Manufacturers will also produce panels larger than 32 inches. These panels will have higher cutting efficiency and greater profits.
Samsung's decline on the LCD screen is mainly due to their focus on AMOLED panels. However, OLEDs are mainly small and medium-sized panels. They are mostly used in smart phones, flat panels and other products. OLED panels used in TVs are not mature enough. The future is very long. The time is still the world of LCD.

Siren and Alarm

A siren is a loud noise-making device. Civil defense sirens are mounted in fixed locations and used to warn of natural disasters or attacks. Sirens are used on emergency service vehicles such as ambulances, police cars, and fire trucks. There are two general types: pneumatic and electronic.

Many fire sirens (used for calling the volunteer fire fighters) serve double duty as tornado or civil defense sirens, alerting an entire community of impending danger. Most fire sirens are either mounted on the roof of a fire station or on a pole next to the fire station. Fire sirens can also be mounted on or near government buildings, on tall structures such as water towers, as well as in systems where several sirens are distributed around a town for better sound coverage. Most fire sirens are single tone and mechanically driven by electric motors with a rotor attached to the shaft. Some newer sirens are electronically driven speakers.

Fire sirens are often called "fire whistles", "fire alarms", or "fire horns". Although there is no standard signaling of fire sirens, some utilize codes to inform firefighters of the location of the fire. Civil defense sirens also used as fire sirens often can produce an alternating "hi-lo" signal (similar to emergency vehicles in many European countries) as the fire signal, or a slow wail (typically 3x) as to not confuse the public with the standard civil defense signals of alert (steady tone) and attack (fast wavering tone). Fire sirens are often tested once a day at noon and are also called "noon sirens" or "noon whistles".

The first emergency vehicles relied on a bell. Then in the 70s, they switched to a duotone airhorn. Then in the 80s, that was overtaken by an electronic wail.
