typical 55 lcd panel size made in china

If Hisense, TCL, Samsung, Vizio, or (in particular) LG"s 55-inch 4K budget televisions aren"t available, I"d recommend buying the AiPlus4K because it"s more or less a slightly newer and better TV than the other OEM-made budget options at Walma

Looking for a 55-inch, 4K, budget, smart TV from Amazon? Thanks to the pandemic, you"ll find a weak selection, high prices, and brands you"ve never heard of, such as the Caixun AiPlus4K (model EC55S1UA). While affordable for a smart TV that does 4K at 60Hz, is it worth $480?

The AiPlus4k is an adequate alternative to other budget 4K televisions. It displays 4K content at 60Hz. That"s suitable for the last generation of consoles, like a PS4 Pro, as well as PC gamers. And its LCD panel"s contrast ratio is good. But the value isn"t equal to better-known television brands.

Caixun (pronounced "Kai-Shuin") is a sub-label of Express Luck Technology, a 20-year-old TV manufacturer out of China. They use panels from a variety of sources, including CSOT, AUO, and others. However, it"s unlikely that anyone in the United States has even heard of them, although you may have owned a television of their design.

Like all 55-inch TVs, the AiPlus4K requires a little assembly, but that"s limited to screwing on its feet. After hooking it up to a power source, you need to configure its smart components for use.

Its 8GB-sized storage capacity has 2GB available to the user. The limited space makes it useful as a streaming box with few installed apps. Don"t expect to play large games, particularly given that Android devices can become progressively slower as free storage decreases.

LED 4K screens don"t look as good as OLED panels, with comparatively mediocre black levels and contrast ratios. However, they"re extremely resilient and long-lasting, being almost immune to burn-in, also known as image retention. While LED-backlight technology isn"t state-of-the-art, it"s more durable and power-efficient compared to OLED panels. And if you"re on a budget, they"re cheaper than the latest LED-related tech, like LG"s NanoCell or Samsung"s Mini LED and Micro LED technologies.

The 4K panel itself doesn"t show any stuck pixels or screen imperfections, although if you did detect one, Caixun"s customer service requires that you return the unit through Amazon"s 30-day return period.

All budget LED-lit IPS LCD panels look bad compared to OLED. You might notice small degrees of uneven black levels around the edges of the screen, and blacks that are nearly grey in dim lighting. The AiPlus4K doesn"t magically solve the problem with LED-lit televisions.

As with most In-Plane Switching (IPS) LCD panels, the 4K display on the AiPlus4K remains adequate from all angles, but the whites deteriorate in quality the further you move away from the dead center. Overall, the screen doesn"t show any serious signs of poor quality.

As with all televisions in this price segment, the refresh rate when using YouTube or other streaming video apps comes in at less than 30Hz. VLC Player indicated that the refresh rate while playing 4K content is 24Hz. Additionally, I noticed high levels of smearing and ghosting while playing back 4K content, but only for dark scenes. Otherwise, the panel"s image quality remained consistent.

To the best of my knowledge, the Sansui ES55XS1A and the AiPlus4K look like the same television. There"s a lot of evidence suggesting that they are the same.

While this does not mean the AiPlus4K is a bad television, it does mean it"s overpriced. And, as of the writing of this article, Amazon"s stock of budget 55-inch LCD smart televisions are severely limited.

There are no teardowns of the AiPlus4K anywhere, but you shouldn"t need one for two reasons. First, disassembly doesn"t require removing security screws. Second, accessing the logic board doesn"t require any special instructions. Simply unscrewing the rear access panel provides a full view of the electronics driving the television.

If you suffer from either a failing capacitor or a desoldered GPU, replacement only requires a soldering iron and basic electronics safety measures. I"d still recommend taking the TV to a repair shop, rather than fixing it yourself, because of the potential for injury. But overall, the AiPlus4K"s electronics are extremely easy to repair, unless you"ve broken the LCD screen, which is difficult and expensive to repair.

If Hisense, TCL, Samsung, Vizio, or (in particular) LG"s 55-inch 4K budget televisions aren"t available, I"d recommend buying the AiPlus4K because it"s more or less a slightly newer and better TV than the other OEM-made budget options at Walmart.

SEOUL (Reuters) - Chinese flat screen makers, once dismissed as second-class players in the global LCD market, are drawing envious looks from big names such as LG Display Co Ltd and Samsung.An employee works inside a LCD factory in Wuhan, Hubei province, May 8, 2013. REUTERS/China Daily

While the Korean giants were busy developing next-generation organic light emitting diode (OLED) TVs, little-known Chinese companies have started selling a type of display that are sharper than the standard LCD and cheaper than OLED.

Until last year, the UHD market had been almost non-existent, with just 33,000 sets sold in the 200 million-unit LCD TV market. Since then, shipments have soared around 20-fold, thanks to China, data from research firm IHS shows.

But its slow introduction into the market and austere prices have thrown open a window of opportunity for UHD makers, in this case Chinese companies like BOE Technology Group Co Ltd and TCL Corp’s LCD unit CSOT.

By comparison, Japanese flat-screen pioneer Sharp Corp reported a razor-thin 0.5 percent margin. LG Display, the world’s No.1 LCD maker, posted a 5.6 percent margin.

Samsung Display, a unit of Samsung Electronics, had a margin of 13 percent, the biggest in the industry. But excluding its fledging OLED business, its LCD margin is between 3 and 7 percent, according to a Bernstein forecast.

“Even with some expansion of the Chinese panel suppliers we do expect Samsung and LG Display to stay dominant and continue production in LCD,” said Sweta Dash, director at IHS.

BOE Technology is now planning to raise 46 billion yuan ($7.5 billion) in the biggest Chinese equity offering this year, to build panel production lines and increase its stake in its LCD venture BOE Display Technology.

One of today’s modern technological wonders is the flat-panel liquid crystal display (LCD) screen, which is the key component we find inside televisions, computer monitors, smartphones, and an ever-proliferating range of gadgets that display information electronically.What most people don’t realize is how complex and sophisticated the manufacturing process is. The entire world’s supply is made within two time zones in East Asia. Unless, of course, the factory proposed by Foxconn for Wisconsin actually gets built.

Liquid crystal display (LCD) screens are manufactured by assembling a sandwich of two thin sheets of glass.On one of the sheets are transistor “cells” formed by first depositing a layer of indium tin oxide (ITO), an unusual metal alloy that you can actually see through.That’s how you can get electrical signals to the middle of a screen.Then you deposit a layer of silicon, followed by a process that builds millions of precisely shaped transistor parts.This patterning step is repeated to build up tiny little cells, one for each dot (known as a pixel) on the screen.Each step has to be precisely aligned to the previous one within a few microns.Remember, the average human hair is 40 microns in diameter.

On the other sheet of glass, you make an array of millions of red, green, and blue dots in a black matrix, called a color filter array (CFA).This is how you produce the colors when you shine light through it.Then you drop tiny amounts of liquid crystal material into the cells on the first sheet and glue the two sheets together.You have to align the two sheets so the colored dots sit right on top of the cells, and you can’t be off by more than a few microns in each direction anywhere on the sheet.The sandwich is next covered with special sheets of polarizing film, and the sheets are cut into individual “panels” – a term that is used to describe the subassembly that actually goes into a TV.

For the sake of efficiency, you would like to make as many panels on a sheet as possible, within the practical limitations of how big a sheet you can handle at a time.The first modern LCD Fabs built in the early 1990s made sheets the size of a single notebook computer screen, and the size grew over time. A Gen 5 sheet, from around 2003, is 1100 x 1300 mm, while a Gen 10.5 sheet is 2940 x 3370 mm (9.6 x 11 ft).The sheets of glass are only 0.5 - 0.7 mm thick or sometimes even thinner, so as you can imagine they are extremely fragile and can really only be handled by robots.The Hefei Gen 10.5 fab is designed to produce the panels for either eight 65 inch or six 75 inch TVs on a single mother glass.If you wanted to make 110 inch TVs, you could make two of them at a time.

The fab is enormous, 1.3 km from one end to the other, divided into three large buildings connected by bridges.LCD fabs are multi-story affairs.The main equipment floor is sandwiched between a ground floor that is filled with chemical pipelines, power distribution, and air handling equipment, and a third floor that also has a lot of air handling and other mechanical equipment.The main equipment floor has to provide a very stable environment with no vibrations, so an LCD fab typically uses far more structural steel in its construction than a typical skyscraper.I visited a Gen 5 fab in Taiwan in 2003, and the plant manager there told me they used three times as much structural steel as Taipei 101, which was the world’s tallest building from 2004- 2010.Since the equipment floor is usually one or two stories up, there are large loading docks on the outside of the building.When they bring the manufacturing equipment in, they load it onto a platform and hoist it with a crane on the outside of the building.That’s one way to recognize an LCD fab from the outside – loading docks on high floors that just open to the outdoors.

LCD fabs have to maintain strict standards of cleanliness inside.Any dust particles in the air could cause defects in the finished displays – tiny dark spots or uneven intensities on your screen.That means the air is passed through elaborate filtration systems and pushed downwards from the ceiling constantly.Workers have to wear special clean room protective clothing and scrub before entering to minimize dust particles or other contamination.People are the largest source of particles, from shedding dead skin cells, dust from cosmetic powders, or smoke particles exhaled from the lungs of workers who smoke.Clean rooms are rated by the number of particles per cubic meter of air.A class 100 cleanroom has less than 100 particles less than 0.3 microns in diameter per cubic meter of air, Class 10 has less than 10 particles, and so on. Fab 9 has hundeds of thousands of square meters of Class 100 cleanroom, and many critical areas like photolithography are Class 10.In comparison, the air in Harvard Square in Cambridge, MA is roughly Class 8,000,000, and probably gets substantially worse when an MBTA bus passes through.

The Hefei Gen 10.5 is one of the most sophisticated manufacturing plants in the world.On opening day for the fab, BOE shipped panels to Sony, Samsung Electronics, LG Electronics, Vizio, and Haier.So if you have a new 65 or 75-inch TV, there is some chance the LCD panel came from here.

In July 2008, TCL announced that it planned to raise 1.7 billion yuan ($249 million) via a share placement on the Shenzhen Stock Exchange to fund the construction of two production lines for LCD televisions; one for screens of up to 42 inches, and the other for screens of up to 56 inches.

In March 2010, TCL Multimedia raised HK$525 million through the sale of shares on the Hong Kong Stock Exchange, in order to fund the development of its LCD and LED businesses and to generate working capital.

Typically, HDR TVs also produce more vibrant, varied colors than other sets. That’s because HDR is often paired with "wide color gamut," or WCG, capability.

Better-performing HDR TVs typically generate at least 600 nits of peak brightness, with top performers hitting 1,000 nits or more. But many HDR TVs produce only 100 to 300 nits. With an underpowered TV, the fire of a rocket launch becomes a single massive white flare. With a brighter television, you’d see tongues of fire and smoke, as if you were really there.

Since the introduction of economic reforms, China"s economy has grown substantially faster than during the pre-reform period, and, for the most part, has avoided major economic disruptions.Figure 3). This has meant that on average China has been able to double the size of its economy in real terms every eight years. The global economic slowdown, which began in 2008, had a significant impact on the Chinese economy. China"s media reported in early 2009 that 20 million migrant workers had returned home after losing their jobs because of the financial crisis and that real GDP growth in the fourth quarter of 2008 had fallen to 6.8% year-on-year. The Chinese government responded by implementing a $586 billion economic stimulus package, aimed largely at funding infrastructure and loosening monetary policies to increase bank lending.Figure 4).

The rapid growth of the Chinese economy has led many analysts to speculate if and when China will overtake the United States as the "world"s largest economic power." The "actual" size of China"s economy has been a subject of extensive debate among economists. Measured in U.S. dollars using nominal exchange rates, China"s GDP in 2018 in nominal U.S. dollars was $13.4 trillion, which was 65.3% of the size of the U.S. economy, according to estimates made by the IMF. China"s 2018 per capita GDP in nominal dollars was $9,608, which was 15.3% of the U.S. per capita level.

Many economists contend that using nominal exchange rates to convert Chinese data (or those of other countries) into U.S. dollars fails to reflect the true size of China"s economy and living standards relative to the United States. Nominal exchange rates simply reflect the prices of foreign currencies vis-à-vis the U.S. dollar, and such measurements exclude differences in the prices for goods and services across countries. To illustrate, one U.S. dollar exchanged for local currency in China would buy more goods and services there than it would in the United States. This is because prices for goods and services in China are generally lower than they are in the United States. Conversely, prices for goods and services in Japan are generally higher than they are in the United States (and China). Thus, one dollar exchanged for local Japanese currency would buy fewer goods and services there than it would in the United States. Economists attempt to develop estimates of exchange rates based on their actual purchasing power relative to the dollar in order to make more accurate comparisons of economic data across countries, usually referred to as purchasing power parity (PPP).

The decline in China"s working age population may have contributed rising wages in China. As indicated in Figure 9, China"s average monthly wages (converted into U.S. dollars) in 1990 were $55, compared with $32 for Vietnam and $221 for Mexico.Figure 10 shows a comparison of labor costs per unit of production for the countries listed in the previous figure, indexed relative to U.S levels. In 2000, China"s unit labor production costs were 42.3 of U.S. levels and by 2018 they rose to 75.5% of U.S. levels.

China"s trade and investment reforms and incentives led to a surge in FDI beginning in the early 1990s. Such flows have been a major source of China"s productivity gains and rapid economic and trade growth. There were reportedly 445,244 foreign-invested enterprises (FIEs) registered in China in 2010, employing 55.2 million workers or 15.9% of the urban workforce.Figure 11, FIEs account for a significant share of China"s industrial output. That level rose from 2.3% in 1990 to a high of 35.9% in 2003, but fell to 25.9% in 2011.Figure 12).

China"s economic growth model has emphasized the growth of heavy industry in China, much of which is energy-intensive and high polluting. The level of pollution in China continues to worsen, posing serious health risks to the population. The Chinese government often disregards its own environmental laws in order to promote rapid economic growth. China"s environmental challenges are illustrated by the following incidents and reports.A 2018 report by ExxonMobil estimated that China contributed about 60% of the growth in global CO2 emissions from 2000 to 2016, and that its emissions would surpass the combined CO2 levels of the United States and EU by 2025.

The relative lack of the rule of law in China has led to widespread government corruption, financial speculation, and misallocation of investment funds. In many cases, government "connections," not market forces, are the main determinant of successful firms in China. Many U.S. firms find it difficult to do business in China because rules and regulations are generally not consistent or transparent, contracts are not easily enforced, and intellectual property rights are not protected (due to the lack of an independent judicial system). The relative lack of the rule of law and widespread government corruption in China limit competition and undermine the efficient allocation of goods and services in the economy. A New York Times article reported that (former) Chinese Premier Wen Jiabao"s family controlled assets worth at least $2.7 billion.th Party Conference. The meeting focused on the need to enhance the rule of law in China, but emphasized the leading role of the Communist Party in the legal system.

The existence of a large and underemployed labor force was a significant factor in China"s rapid economic growth when economic reforms were first introduced. Such a large labor force meant that firms in China had access to a nearly endless supply of low-cost labor, which helped enable many firms to become more profitable, which in turn led them to boost investment and production. Some economists contend that China is beginning to lose this labor advantage. According to the Chinese government, the size of its working age population (ages 16 to 59) peaked at 925 million in 2011, but then fell for seven consecutive years to 897 million in 2018. The Chinese government projects that its working age population will drop to 830 million by 2030 and to 700 million by 2050. If these projections prove accurate, the Chines working age population could drop by 225 million individuals (2011-2050).
