CMRC (market research institution belonged to Statistics China before) named Topway one of the top 10 LCD manufactures in China.

The Company engages in the R&D, manufacturing, and sale of LCD panels. It offers LCD panels for notebook computers, desktop computer monitors, LCD TV sets, vehicle-mounted IPC, consumer electronics products, mobile devices, tablet PCs, desktop PCs, and industrial displays.

Founded in 2008，Yunnan OLiGHTEK Opto-Electronic Technology Co.,Ltd. dedicated themselves to developing high definition AMOLED (Active Matrix-Organic Light Emitting Diode) technology and micro-displays.

Chinese display panel makers accounted for nearly half of the share in the global liquid crystal display TV panel market in the first half of this year, dominating the industry.

Beijing-based market researcher Sigmaintell Consulting said shipments of LCD TV panels worldwide totaled 140 million pieces in the year"s first half, up 3.6 percent compared with the same period a year ago.

The shipment of BOE"s LCD TV panels stood at 27.6 million in the Jan-June period while LG Display followed with 22.7 million, down 4.5 percent year-on-year. Innolux Display Group was in third place, having shipped 21.9 million units.

Shenzhen China Star Optoelectronics Technology Co Ltd, a subsidiary of consumer electronics giant TCL Corp, ranked fourth, shipping 19.3 million pieces of TV panels. Chinese panel makers accounted for a 45.8 percent share in the global LCD TV panel market.

Separately, BOE"s Gen 10.5 TFTLCD production line has entered operation in Hefei, Anhui province. The plant will produce high-definition LCD screens of 65 inches and above.

"China"s semiconductor display industry has taken large steps forward in the past decade, changing the display industry"s global competitive landscape. China has transformed into the world"s largest consumer market and manufacturing base for display terminals, with huge market potential," said BOE Vice-President Zhang Yu.

CSOT also announced in November last year that its Gen 11 TFT-LCD and active-matrix OLED production line had officially began operation. The project will produce 43-inch, 65-inch and 75-inch liquid crystal display screens.

TCL founder and chairman Li Dongsheng said China will likely take the lead in the semiconductor display sector across the world within the next three to five years.

"China will play an active and vital role in prompting the development of the semiconductor display industry, which has a high entry threshold and needs high investment," Li said.

China is expected to replace South Korea as the world"s largest flat-panel display producer in 2019, a report from the China Video Industry Association and the China Optics and Optoelectronics Manufacturers Association said.

Compared with traditional LCD display panels, OLED has a fast response rate, wide viewing angles, high-contrast images and richer colors. It is thinner and can be made flexible.

"The penetration rate of such TVs in China is relatively low, while such type of TV has become the representative of high-end TVs in the United States, Europe, Japan and other countries," said Park Changhyuk, general manager of LG Display China"s promotion unit.

There are several display panel manufacturers in mainland China of which JDF(BOE) and TM(Tianma) stand out noticeably. JDF has gradually transformed its 6th production line into small-to-medium-size displays since 2014 and now JDF proceeds this plan and concentrates production capacity in this field in an all-around way.

As a matter of fact, TM(Tianma) has already transformed its display size and capacity altogether in late 2013 in prior of JDF(BOE), focusing on small-to-medium-size displays.

In addition to this, though SC which was vigorously supported by Foxconn had been performing mass production for LTPS, TFT, LCD displays at the beginning of 2012, did not make a great progress for the reason that SC failed to neither win over the Apple iPhone orders and nor get authorization in CG Si and IGZO technology of Sharp.

But do you know which iPhone 6 LCD made by these three display penal manufacturers is more cost-effective? Let’s go on with this article and sort things out. Not too long ago, REWA has analyzed the JDF(BOE) and LT(IVO) China made iPhone 6 LCDs in some ways. After several months’ development, how is the situation now? We have tested 3 mainstream China-made iPhone 6 LCDs by JDF(BOE ), TM(Tianma) and SC from aspects of “Appearance” and “Function” in order to make a comparison with OEM ones and give us clarity of thought.

After installed in the mobile devices, it’s much easy for us to find that all these three China made LCDs have a small gap between the LCD and device body, especially SC.

It can be observed visually that LCD Display and Touchscreen digitizer flex cable made by JDF, TM and SC are different in texture. 5) Structure Generally speaking, there are two kinds of mainstream cell phone display constructions of formation, “G+G” and “In-cell”.

Compared with the In-cell structure of OEM LCD, JDF, TM and SC which use G+G touch screen display technology thus cause their overall thickness greater than the OEM ones.

Testing Touch screen digitizer by moving the app icon in all directions including swiping from the edge of the screen, JDF, TM and SC display have no problems with touch function.

Testing LCD display in the pure color of gray, white and black, a part of JDF, TM and SC LCDs have somewhat degree problems of backlight leakage, but it does not affect the normal use and can be ignored in a certain sense. Note: The severity of this problem in the actual situation is a lot more slight than the captured pictures above.

After playing video for 72 hours, JDF, TM, SC have no obvious differences with the OEM ones. CONCLUSION From a series of tests we can find there are only a few differences between OEM display and China made LCDs. In terms of quality, JDF & TM are better than SC. For Price, JDF is more favorable than TM. Therefore, on the market condition that OEM LCDs being out of stock, JDF LCD is the most cost-effective choice for you. Want to order our products?

Flat-panel displays are thin panels of glass or plastic used for electronically displaying text, images, or video. Liquid crystal displays (LCD), OLED (organic light emitting diode) and microLED displays are not quite the same; since LCD uses a liquid crystal that reacts to an electric current blocking light or allowing it to pass through the panel, whereas OLED/microLED displays consist of electroluminescent organic/inorganic materials that generate light when a current is passed through the material. LCD, OLED and microLED displays are driven using LTPS, IGZO, LTPO, and A-Si TFT transistor technologies as their backplane using ITO to supply current to the transistors and in turn to the liquid crystal or electroluminescent material. Segment and passive OLED and LCD displays do not use a backplane but use indium tin oxide (ITO), a transparent conductive material, to pass current to the electroluminescent material or liquid crystal. In LCDs, there is an even layer of liquid crystal throughout the panel whereas an OLED display has the electroluminescent material only where it is meant to light up. OLEDs, LCDs and microLEDs can be made flexible and transparent, but LCDs require a backlight because they cannot emit light on their own like OLEDs and microLEDs.

Liquid-crystal display (or LCD) is a thin, flat panel used for electronically displaying information such as text, images, and moving pictures. They are usually made of glass but they can also be made out of plastic. Some manufacturers make transparent LCD panels and special sequential color segment LCDs that have higher than usual refresh rates and an RGB backlight. The backlight is synchronized with the display so that the colors will show up as needed. The list of LCD manufacturers:

Organic light emitting diode (or OLED displays) is a thin, flat panel made of glass or plastic used for electronically displaying information such as text, images, and moving pictures. OLED panels can also take the shape of a light panel, where red, green and blue light emitting materials are stacked to create a white light panel. OLED displays can also be made transparent and/or flexible and these transparent panels are available on the market and are widely used in smartphones with under-display optical fingerprint sensors. LCD and OLED displays are available in different shapes, the most prominent of which is a circular display, which is used in smartwatches. The list of OLED display manufacturers:

MicroLED displays is an emerging flat-panel display technology consisting of arrays of microscopic LEDs forming the individual pixel elements. Like OLED, microLED offers infinite contrast ratio, but unlike OLED, microLED is immune to screen burn-in, and consumes less power while having higher light output, as it uses LEDs instead of organic electroluminescent materials, The list of MicroLED display manufacturers:

Sony produces and sells commercial MicroLED displays called CLEDIS (Crystal-LED Integrated Displays, also called Canvas-LED) in small quantities.video walls.

LCDs are made in a glass substrate. For OLED, the substrate can also be plastic. The size of the substrates are specified in generations, with each generation using a larger substrate. For example, a 4th generation substrate is larger in size than a 3rd generation substrate. A larger substrate allows for more panels to be cut from a single substrate, or for larger panels to be made, akin to increasing wafer sizes in the semiconductor industry.

Samsung Display will stop producing LCD panels by the end of the year. The display maker currently runs two LCD production lines in South Korea and two in China, according to Reuters. Samsung tells The Verge that the decision will accelerate the company’s move towards quantum dot displays, while ZDNetreports that its future quantum dot TVs will use OLED rather than LCD panels.

The decision comes as LCD panel prices are said to be falling worldwide. Last year, Nikkei reported that Chinese competitors are ramping up production of LCD screens, even as demand for TVs weakens globally. Samsung Display isn’t the only manufacturer to have closed down LCD production lines. LG Display announced it would be ending LCD production in South Korea by the end of the 2020 as well.

Last October Samsung Display announced a five-year 13.1 trillion won (around $10.7 billion) investment in quantum dot technology for its upcoming TVs, as it shifts production away from LCDs. However, Samsung’s existing quantum dot or QLED TVs still use LCD panels behind their quantum dot layer. Samsung is also working on developing self-emissive quantum-dot diodes, which would remove the need for a separate layer.

Samsung’s investment in OLED TVs has also been reported by The Elec. The company is no stranger to OLED technology for handhelds, but it exited the large OLED panel market half a decade ago, allowing rival LG Display to dominate ever since.

Although Samsung Display says that it will be able to continue supplying its existing LCD orders through the end of the year, there are questions about what Samsung Electronics, the largest TV manufacturer in the world, will use in its LCD TVs going forward. Samsung told The Vergethat it does not expect the shutdown to affect its LCD-based QLED TV lineup. So for the near-term, nothing changes.

One alternative is that Samsung buys its LCD panels from suppliers like TCL-owned CSOT and AUO, which already supply panels for Samsung TVs. Last year The Elec reported that Samsung could close all its South Korean LCD production lines, and make up the difference with panels bought from Chinese manufacturers like CSOT, which Samsung Display has invested in.

Samsung has also been showing off its MicroLED display technology at recent trade shows, which uses self-emissive LED diodes to produce its pixels. However, in 2019 Samsung predicted that the technology was two or three years away from being viable for use in a consumer product.

BOE Technology Group and TCL China Star Optoelectronics Technology (TCL CSOT) are among the Chinese panel makers to have ramped up output since around 2019 with generous state subsidies. China is gaining on South Korea, whose share of capacity is seen reaching 55% for 2022 in an October estimate by U.S. market intelligence firm Display Supply Chain Consultants (DSCC).
