lcd panel issue supplier

VISLCD has been engaged in LCD production and sales for 9 years, and we have met many customers who shared with us that they had encountered unreliable LCD suppliers.

For example, the answer is not what you asked for, the LCD product cannot be delivered on time, the price of the LCD suddenly increases, the LCD module suddenly breaks down during the use of the product, or even the LCD is discontinued after less than 1 year of delivery…etc. In addition, there are many customers who are not sure what type of LCD supplier they are looking for.

In view of all the above, VISLCD has written this article to share knowledge about LCD suppliers and other issues related to LCD. We believe it will be helpful to LCD customers.

To understand LCD suppliers, we first need to know what kinds of LCD suppliers are available. Then LCD customers can find the right supplier based on information such as their product  applications, LCD requirements and forecast volume.

LCD original manufacturer refers to the original manufacturer of LCD panel. Originated from the USA in the 1960’s, after more than 50 years of development, the manufacturers are now mainly located in China mainland, Korea and Taiwan. Among them, the Chinese manufacturers in recent years rely on the rapid scale, technology development and price advantage, has gradually occupied the main market share.

The video below is an official video presentation of the BOE display factory and Century Display (CTC), which will give you a more visual understanding of the original LCD manufacturer.

The 5.1 generation TFT-LCD line of Century Display in Shenzhen, China, for example, has been put into operation since 2008 with a cumulative fixed investment of more than $4 billion, and the cost of water, electricity, employee wages and equipment depreciation is as high as $0.5~100 million/month. The monthly production capacity is about 100,000 sheets ( 1300*1200mm/sheet). If all of them are used to produce 7-inch LCD panels, then the monthly shipment volume is up to 9,000,000 pcs. Therefore, a very large monthly shipment volume is required to meet the normal operation of the factory.

This is only the 5.1 generation TFT-LCD line, if it is 8.5 generation line or even 10 generation line or more, then the cost and shipment volume may be several times or even ten times more. It should be noted that the number of generations of LCD lines does not mean that the technology is high or low. The higher the generation, then the larger the size of the LCD can be put into production, of course, the greater the volume of shipments and investment amount.

LCD original manufacturers generally provide mainly LCD panels, but also provide COG (LCD + IC), FOG (LCD + IC + FPCA cable) and other kinds of LCD semi-finished products. Also includes a small amount of the original LCD module. But the original LCD factory will only deal with the famous brand companies directly (such as Apple, Dell, Xiaomi, etc.), or through agents to ship. And the MOQ quantity requirement is very high (generally 1,000,000 pcs/month or more), the unit price of original LCD module is also high and the degree of customization is low.

LCD original manufacturers usually have an order MOQ requirement for their agents, which translates into an LCD unit quantity of no less than 100,000pcs/month. When the LCD demand is high, this will not be a problem; but when the market is low, the agent must buy the agreed MOQ quantity of LCD from the original LCD manufacturer even if there is no customer demand for the time being. So when the low season, if your order quantity is large enough, then you may get a very good LCD panel price from the LCD agent, which may even be lower than the agent’s purchase price.

LCD module manufacturers is to purchase LCD semi-finished products (such as LCD panel, COG or FOG) from LCD agents, then purchase ICs from IC agents, produce or purchase backlight, FPCA cable and touch screen components, and then integrate all the above components into LCD module or touch LCD module. LCD module factories vary in size from tens of millions of pcs to hundreds of thousands of pcs shipped per month.

Medium and large size module factory generally get the semi-finished products are FOG LCD (also known as open cell LCD) from the original LCD manufacturers or LCD agents, and then add the backlight assembly into the finished LCD module. The advantage of doing so is that the quality is relatively stable, but the degree of customization will be much lower. Because FOG LCD already includes FPCA cable, generally speaking, the only thing that can be customized is the brightness of the backlight and the touch panel and cover glass (if needed). The rest are difficult to change, unless the customer’s LCD demand is very large.

The small and medium size module factory after years of mature development of the industry, the degree of customization will be much more flexible. The semi-finished products are mainly LCD panels, which means that the backlight size, backlight brightness, FPCA cable design, shape and PIN number, as well as the touch panel and cover glass can all be customized according to the customer’s requirements. But the MOQ requirement is higher for the backlight size. Other parts of the customization generally require LCD MOQ of at least 2,000~5,000 pcs, which varies depending on the LCD size.

Since LCD module manufactures vary in size and quality control(especially small and medium size LCD module factories), and most of the components are sourced, the selection of module factories is particularly important if customers want to buy LCDs with good quality and competitive prices.

For example, if the factory’s customers are mostly low-cost products or repaired product manufacturers, then it can be assumed that the quality of his products is not too good, LCD panels and some other components may be B-grade products, not A, can only meet short-term use.

This is essential to ensure supply. In case of supply shortage, many module factories with insufficient upstream channels sometimes cannot even start production. Because they can not buy raw materials such as LCD panels and ICs.

As the name implies, trading companies do not have their own factories, but directly sell finished LCD products from LCD resellers or LCD modules from module manufacturers. Generally speaking, the LCD prices of trading companies are relatively high and the quality and reliability are a little weaker. However, there is no shortage of good trading companies with good quality management teams and good upstream channel resources. The biggest advantage of trading companies is their flexibility, which can meet the diversified needs of customers.

2) Shenzhen has 3 types of buildings related to lcd (including other electronic products): office buildings, factories and markets. Almost all LCD panel and IC agents are located in various office buildings in Shenzhen, while component factories such as FPCA, Touch panel and backlight are located in various industrial parks in the suburbs. It is possible to find the right components and develop new products in the shortest time. Of course, there is also the famous Huaqiang bei(north) Electronic Market, a very complex place.

VISLCD was a trading company in the early days. But after nearly 9 years of development, it has developed into a combination of LCD module factory and LCD agent. The company is located in LCD base Shenzhen, China and operates in both Hong Kong and Shenzhen. We have our own module factory and have direct relationship with Century Display, LG, HKC and other LCD original manufacturers. Our main employees are also from these LCD manufacturers. We also accept all kinds of customized LCD business. Therefore, VISLCD is one of the best choices for medium-sized customers in terms of quality stability, semi-finished parts supply and customization.

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.

Chances are you selected an LCD display supplier to work with your CM and now feel locked into the relationship. You’ve already gone through the qualification process, investing time and money. Not to mention approving the PO in good faith, believing the CM would be getting the right cost, on-time delivery, and high-quality components from your LCD supplier.

A CM had a quality issue with an LCD module. The CM felt comfortable notifying the LCD supplier of the problem. A comprehensive QA check at the supplier’s factory did not reveal any quality issues. The LCD supplier, taking accountability for their role in the end product, scheduled a visit to the CM’s factory. Working collaboratively with the CM, they discovered missing steps in the CM’s process that were compromising the quality of the displays. Quick and intelligent action meant the impact was negligible. The OEM, while informed, was not involved or burdened throughout this process.

Given the LCD supplier’s role and responsibilities, they should keep the OEM informed on aspects that pose a significant impact on products or customer perception:

Lead time: Contrary to the lines you may be fed, lead-time problems are not just part of doing business. Sure, uncertainty and circumstances happen, but an experienced LCD supplier will have safety nets in place to address this, like safety stock of the longest lead time component, multiple delivery options, and pull with their factory to increase or speed production.

Quality: Shoddy displays? Field failures? Dimensional tolerances not being met? These types of quality issues are a sure sign it’s time to start a new LCD supplier search.

For specialty components like LCD displays, it’s typical that you dictate to your CM the supplier they need to use. And if you are observing any issues with lead time, quality, performance, cost, or obsolescence, you should look for an alternate supplier.

Find an LCD display supplier that has experience dealing with a contract manufacturer. There are some items that are dealt directly with the CM, such as schedules, payments, and RMAs. But the supplier needs to know when to get the OEM involved, which is any time there may be a significant impact to your products or customer perception.

Liquid crystal displays (LCDs) are the most widely used display technology. Their applications cover TV, mobile phone, appliances, automotive, smart home, industrial meters, consumer electronics, POS, marine, aerospace, military etc. LCD screen display problem can occur for several reasons.

Effect of environmental conditions on the LCD assembly. Environmental conditions include both the effects of temperature and humidity, and cyclic loading.

Effect of manufacturing process. With the development of LCD for more than 40 years and the modern manufacturing equipment, this kind if defects are getting rear.

Common failures seen in LCDs are a decrease in screen contrast, non-functioning pixels or the whole display, and broken glass. Different kinds of LCD display problem need to have different kinds of fix methods or make the decision not worthwhile to repair.

Broken glassIf you accidently drop the LCD and you find it broken on the surface but the display still works. You might just break the touch panel; you can find a repair house or find a youtube video to replace the touch panel. If you find the display not showing, especially you find the fluid leaking out. You need to reply the whole display modules.

Dim LCD displayLCD can’t emit light itself. It uses backlight. Normally, the backlight is not fully driven, you can increase the LED backlight to make a dim LCD display brighter. But if you LCD display has been used for a long time, it is possible that the LED backlight has to be the end of life (not brightness enough) if you turn on 100% backlight brightness. In that case to fix LCD screen, you have to find a way to change the backlight. For some display, it is an easy job but it can be difficult for other displays depending on the manufacturing process.

LCD has white screen – If a LCD has a white screen which means the backlight is good. Simply check your signal input sources which are the most causes. It can also be caused by the display totally damaged by ESD or excess heat, shock which make the LCD controller broken or the connection failure which has to be repaired by professionals.

Blur ImagesAs the LCD images are made of RGB pixels, the screen shouldn’t be blur like old CRT displays. If you do see blur images, they might be caused by two reasons. 1) LCD has certain response time, if you are playing games or watch fast action movies, some old LCD displays can have image delays. 2) The surface of the LCD is made of a layer of plastic film with maximum hardness of 3H. If you clean the surface often or use the wrong detergent or solvent which cause the surface damage. To fix damage on LED screen it’s need to be changed with professionals.

That’s probably why you need to reevaluate today. Asking the right questions during this process clarifies the conditions you need to work successfully with the LCD display supplier.

Most of the review process is about asking the right questions about your needs to the supplier. Knowing exactly what display requirements the new LCD manufacturer should meet will inform you that they should what are the functions?

The reasons for this can be as varied as mechanical or motion-based constraints or temperature/environmental problems. There are also optical considerations such as contrast, brightness, response time, and perspective, as well as durability and interface requirements. You may also have custom features, such as a button or custom icon on a glass or touch panel.

There is a significant difference between the demand for 2,000 and 200,000 screens per year, not only in large quantities but also in determining whether LCD vendors can effectively meet the demand for mass-produced displays.

Whether you need a JIT order, late inventory, or less than the lead time order, you will determine what LCD display manufacturers need to use to ensure seamless integration.

It seems there will always be a LCD manufacture on their way to bankruptcy. As is true in any industry, there will always be someone who has a lower price for a LCD display custom solution. Lower price does not necessarily equate to lower cost.

Do your research and make sure the supplier has been in business for several years. Does this supplier really understand LCD technology, or are they a broker that also supplies, PCB’s, capacitors and duct tape?

Liquid crystal display technology changes at a very rapid pace and requires an LCD company who deals with LCDs and LCDs only. Would you service your new car at a repair shop that also buys gold and sells low cost health insurance? You get what you pay for.

When designing your custom LCD make sure the LCD supplier knows the difference between STN and FSTN, or the advantages and disadvantages of EL backlight versus a LED backlight. Is this LCD supplier knowledgeable about the different LCD technologies available today. Do they know the pros and cons of each technology? Can they help you select the best LCD technology for your product taking into consideration the power source, environment exposure, best viewing angle of the display used in your product?

Focus Display Solutions (aka FocusLCDs) has been in business for 19 years. We deal strictly with LCDs and we know the industry and our product. We are also ISO 9001 certified.

Yes, you will save money if everything goes perfect. If you don’t mind making phones calls to the factory at 2am to resolve issues that come up; and you accept that many times off-shore LCD suppliers will modify your LCD display without notifying you.

If you are a company that purchases several different LCD’s a year and have a strong engineering department, you could realize a cost savings. On the other hand, if this is an ‘experiment’ and you need to get to market on time, your sample displays must match production displays; you may want to take a pass. If your LCD display is a low cost segment LCD and things go wrong, you may only be out a few thousand dollars, but if you need a larger color TFT display when things hiccup, your loss is increased to several thousand dollars.

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:

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.
