Five simple words that can equate to significant LCD display challenges for you. Here’s how you can successfully address and resolve these 5 LCD display challenges:

Proactively address this challenge with the LCD display provider and within your company. Internally, assure suppliers’ lead-times are accurate in your MRP. Additionally, maintain a 2-4-week buffer stock or more depending on lead-times and component scarcity.

The LCD display supplier can also carry a buffer stock for your application. Reactively, the LCD display supplier should offer expedited options. Effective display provider can pressure the upstream supply chain, adjust production schedules, ship partial quantities and accelerate shipments. Applying these solutions eliminates most delivery problems and handles unplanned customer demand (a good thing!).

Find a display provider that is prepared for and addresses obsolescence when it rears its ugly head. Display providers who are manufacturing more customized systems are more likely to work with your needs than high-volume suppliers. Understand what would cause an LCD display to become obsolete. Your ideal design partner(s) will design for obsolescence mitigation. Then, by giving a long end-of-life (EOL) notice period, the LCD display provider can react by creating safety stock, sourcing alternates and re-engineering your display around a readily available replacement. Additionally, they should plan development of a compatible replacement so your product development doesn"t need to change. Obsolescence management safeguards your product line and down the road - your bottom line.

Quality issues generally arise in a few ways. First, the LCD display"s failure to meet the performance specification as intended. This involves defining what"s required to satisfy the product"s intent and customers" needs. Next, there are the optical and mechanical aspects of LCD display manufacturing. This includes meeting dimensional tolerances and maximum defect limitations.

A supplier that manufactures to your specific needs will minimize quality issues due to their ability to bring flexibility and expertise by modifying the LCD display for your specific product, and then actively supporting ongoing product improvements.

Defining “performance” begins with the application. Who is the target market or end user and how will they interact with the LCD display? In what environment will it be used? How is it being sold or demonstrated to customers? What data does the LCD display need to convey? Must it be readable by the visually impaired?

When performance is fully understood, we can define the idealdisplay type, size, pixel density, contrast, temperature range, brightness, color gamut response time, etc. Over-specifying any of these factors adds unnecessary cost, while under-specifying will detract from the end product"s usability. Ensure performance is optimized in order for your application to be successful. It is key to find an LCD display provider who is willing to adjust and customize these particular variables and explain them to you in terms of the end user experience.

Another cost challenge is system-level manufacturability. This is where display integration improvements can reduce product complexity, improve manufacturing time, and reduce system level manufacturing defects. For the most seamless LCD display integration, there are additional components such as buttons, LEDs, PCB boards, and connectors that are more efficiently integrated on the display rather than a separately assembled component. Clearly in this case, the LCD display cost will go up, but when done right, the system level cost is reduced to result in a net gain.

Choosing the right supplier, based on your volume and quality needs is essential. Then implement the optimal LCD display solution with the optimal features and performance.

Many Apple products use liquid crystal displays (LCD). LCD technology uses rows and columns of addressable points (pixels) that render text and images on the screen. Each pixel has three separate subpixels—red, green and blue—that allow an image to render in full color. Each subpixel has a corresponding transistor responsible for turning that subpixel on and off.

Depending on the display size, there can be thousands or millions of subpixels on the LCD panel. For example, the LCD panel used in the iMac (Retina 5K, 27-inch, 2019) has a display resolution of 5120 x 2880, which means there are over 14.7 million pixels. Each pixel is made up of a red, a green, and a blue subpixel, resulting in over 44 million individual picture elements on the 27-inch display. Occasionally, a transistor may not work perfectly, which results in the affected subpixel remaining off (dark) or on (bright). With the millions of subpixels on a display, it is possible to have a low number of such transistors on an LCD. In some cases a small piece of dust or other foreign material may appear to be a pixel anomaly. Apple strives to use the highest quality LCD panels in its products, however pixel anomalies can occur in a small percentage of panels.

In many cases pixel anomalies are caused by a piece of foreign material that is trapped somewhere in the display or on the front surface of the glass panel. Foreign material is typically irregular in shape and is usually most noticeable when viewed against a white background. Foreign material that is on the front surface of the glass panel can be easily removed using a lint free cloth. Foreign material that is trapped within the screen must be removed by an Apple Authorized Service Provider or Apple Retail Store.

As the display industry stays in stagnation, Taiwan-based PMOLED panel makers, including Ritdisplay and Wisechip Semiconductor, have been venturing into new business segments.

PMOLED (passive matrix OLED) panel maker Ritdisplay has stepped into battery business by establishing subsidiary battery maker Ritwin and investing in Welltech Energy, and expects the battery business to mainly drive business growth in the future, according to the company.

Sales promotion of TVs at the Double 11 (November 11) online shopping festival in the China market and the Black Friday & Cyber Monday shopping festival in the US market has helped TV vendors lower inventory levels and, in turn, is conducive to a rebound in demand for TV-use LCD panels, according to president James Yang for TFT-LCD panel maker Innolux and president Frank Ko for fellow maker AUO.

Samsung Display (SDC) shipped 86.3 million OLED panels for smartphones and smart wearable devices globally in third-quarter 2022, taking a worldwide market share of 62.9%, down 5.9pp sequentially, iNews 24 cited Stone Partners statistics as indicating.

Channel retailers are launching significant price competition to stimulate TV sales during the Black Friday shopping season in the US, optimizing the availability of affordable TV panel prices, according to market sources.

China-based display panel maker BOE Technology recently made an investment in Chinese smartphone vendor Honor, a partnership that industry observers say will allow the former to increase handset-use OLED panel shipments and the latter to secure panel supply.

Display panel makers, with demand and product prices dropping, have temporarily stopped placing manufacturing equipment since mid-2022, according to panel inspection equipment maker Favite.

AU Optronics (AUO) shipped LCD panels totaling 1.281 million square meters in October, increasing 3.1% sequentially, while Innolux shipped 8.77 million large-size panels and 21.9 million small- to medium-size ones in the month, respectively decreasing 4.9% and 6.7% sequentially, according to the companies.

China-based display panel maker BOE Technology has become the largest shareholder of China-based LED epitaxial wafer and chip maker HC SemiTek via the latter"s private placement, according to industry sources.

Considering that the US has launched a tech war against China by prohibiting the exports of advanced semiconductors involving US-developed technologies and related manufacturing equipment to China, if the conflict spills over to display panels, the US is also able to take measures to stall OLED panel production in China.

Samsung Electronics plans to increase its purchases of LCD panels in 2023 from non-China suppliers, such as Taiwan-based AU Optronics and Innolux, according to industry sources.

Panel maker Innolux has begun providing e-paper module products to clients for multiple applications, according to company president James Yang, as the company transforms itself into a system integrator.

Aiming to become more competitive internationally in its liquid crystal display [LCD] television business, Sharp Corp. (OTCPK:SHCAY) has opened a new plant capable of producing the world’s largest LCD panels and began selling LCD televisions with 42-inch screens and larger in Japan, the United States and Europe earlier this month. Katsuhiko Machida, the firm’s president, said: “With our new plant, we can improve our global strategy. No other company can produce 52-inch full-spec high-definition [HD] LCD televisions as efficiently as we can. This is our strength on which we can compete with our rivals in the global market.”

Thanks to its strong LCD business, Sharp has thrived in recent years. The firm’s consolidated sales in fiscal 2005 were 2.8 trillion yen, a 10.1 percent increase from the previous year. Its operating profits also increased by 8.4 percent to 163.7 billion yen.

However, Sharp’s global share in LCD television sales has decreased because its production capacity had reached its limit, and the firm could not supply enough LCD television sets to meet demand. In 2004, the firm had the largest share in value, about 25 percent, according to a survey by DisplaySearch. But it was overtaken by Sony Corp. (SNE) and Samsung Electronics Co.

After upgrading display capacity for six straight issues on improved market conditions in LCDs, DSCC has now lowered its display capacity forecast for four consecutive quarters on delays and cancellations as conditions worsen and remain weak. Prices were recently at marginal costs for LCD TV panels and it is projected that it will take until 2H’23 for prices to rise above cash costs.

Panel suppliers are mostly delaying new capacity decisions given the weak market conditions in the display market. The situation is particularly dire in LCDs where LCD TV panel prices approached marginal cost levels and BOE’s Chairman indicated they won’t build any more LCD TV fabs, resulting in the cancellation of B17+ and its removal from our forecast. The weakness in LCDs also spread to OLED spending since there is an oversupply there also and most OLED manufacturers also produce LCDs and are currently losing money. Samsung Display is the exception as it earned record OLED operating profits and operating margins in Q4’22 helped by strong iPhone 14 Pro/Pro Max demand and LG Display’s challenges getting qualified for the 14 Pro Max.

The central promotional event of the holiday season happens this week, and retailers will be offering all-time low prices for TVs during Black Friday. The unprecedented decline in LCD TV panel prices continues to flow through to retail prices in the US, and the competition from LCD is also pulling down OLED TV prices, which are also hitting all-time lows.

Now that all of the industry’s flat panel display makers have reported their Q3’22 financial results, we update our industry profile. The third quarter showed a gaping chasm between OLED-focused display makers, especially Samsung Display, and the companies focused on LCD technology. For LCD makers, it was the worst quarter in years and perhaps the worst ever. Meanwhile, Samsung Display recorded its highest profits ever in the first quarter after it discontinued LCD production.

As revealed in DSCC’s latest release of the OLED Shipment Report – Flash Edition, OLED panel revenues decreased 11% Y/Y on a 17% Y/Y decline in panel shipments. Smartphones, tablets and TVs, which have a combined 70% unit share and 85% panel revenue share, decline while other categories had Y/Y unit growth.

Last week, we reported on the warning that Apple issued regarding the temporary impact to the iPhone 14 Pro and iPhone Pro Max as a result of the COVID-19 outbreak at the Foxconn facility in located in Zhengzhou, China.

Apple issued a notice last week on their website noting that COVID-19 restrictions have temporarily impacted the primary iPhone 14 Pro and iPhone 14 Pro Max assembly facility located in Zhengzhou, China. The facility is operating at significantly reduced capacity. The Foxconn facility in Zhengzhou China has been dealing with a COVID-19 outbreak since mid-October that has caused panic among many of its workers.

In October 2022, headline inflation numbers in the US continued their slow but steady decrease from their highest point in more than 40 years. Meanwhile, the steep declines in LCD TV panel prices that started in the second half of 2021 are continuing to flow through to retail and resumed their downward trend after a one-month pause in September.

After fifteen months of decreases, LCD TV panel prices finally hit bottom in September 2022 and prices for several sizes increased in October. We now expect to see a modest increase in prices through the end of the year with prices plateauing in the first quarter above their all-time lows. The last phase of the downward spiral in panel prices was characterized by a massive inventory drawdown in the display supply chain and a corresponding massive reduction in fab utilization by panel makers. With some panel makers delaying to resume production until prices increase, the industry has seen prices edge up toward cash cost levels.

After a long, hard day, you finally sit down to catch up on your favorite show. But when you hit the power button on your remote control, your TV screen stays black! You try pressing the remote’s power button again and again from every angle, but still, your TV has no picture. If this sounds familiar, you’ve likely fallen victim to one or more TV screen issues.

What causes a TV screen to go black? Software issues, loose connections, or backlight problems are usually behind black TV screens. Learn about each of these causes and get tips for troubleshooting them so you can get back to relaxing with your favorite TV shows, movies, and video games.

If your TV screen is black and there’s no sound, you’ll want to check for an LED light or a small indicator light that tells you the TV has power. If there is no power to the TV while it is plugged in, there may be an issue with the outlet or fuse box in your home. However, if the TV is on but the screen is black, the problem could lie with your TV’s software.

Unplug the TV from the wall, and, if possible, remove the power cord from the back of the TV to perform a soft reset. Wait 30 seconds, and plug the TV back into a working outlet to test it again. If you’re still having screen issues, you might want to bring in an expert — they’ll know how to fix your TV’s black screen.

If your TV screen goes black but the sound still works, the first thing to check is the input source to ensure it is turned on and operating correctly. This includes external devices like cable boxes, video game consoles, laptops, and streaming devices. Once you’re sure the input source is working properly and you have the right input settings, check the cable connections. In many instances where the TV screen is black but the audio works, poor cable connections could be the issue.

Some TV displays, such as LCD screens, use a backlight to illuminate the picture. If the backlight burns out or stops working, it will result in a blank TV screen.

You’ve run all the tests, checked all the ports, and ensured your TV has power, but your TV screen is still black! There could be a more complicated (and expensive) issue, so it might be time to ditch your old TV for an upgrade.
