5 Key LCD Display Challenges

Delivery. Obsolescence. Quality. Performance. Cost.

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:

1. Delivery

Missed deliveries are a killer. With even just one component missing, an assembly line goes down, affecting operations, missing revenue goals and failing customers. Components often have long and variable lead times which can lead to production and subsequent delivery problems if they&#;re not managed quickly and effectively.

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!).

2. Obsolescence

Obsolescence is tough to plan ahead for, causes significant production delays, may force you to incur costly redesign and often can be the death of a product.

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.

3. Quality

A manufacturing LCD display failure is an expensive issue. It&#;s even more expensive later.

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.

 

4. Performance

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 ideal display 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.


5. Cost

An LCD display's cost is an obvious challenge as it&#;s usually the most expensive component. Adding to the challenge is the fact that cost is also difficult to quantify and properly understand. It&#;s perceived as the easiest to measure, but unfortunately, it&#;s commonly evaluated incorrectly.

Determining the right price to pay depends on three factors. What does the display need to do? What does the display NOT need to do? And lastly, what quantity is needed? In most cases the ideal option is a custom or semi-custom display perfectly designed for its application. Despite what many think, this is often the most cost-effective solution.

With greater volume, you expect a lower price point, which goes hand in hand with provider selection. Oversimplifying this, imagine three categories; low-volume - standard product distributors; mid-volume - built-to-order custom and semi-custom suppliers; and high-volume - consumer market suppliers. As you can imagine, you will never get to the optimal volume pricing with a low volume stocking distributor for a high-volume consumer product. Identify where you fit and then work with the right provider who serves that particular category.

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.

Lastly, you need to know system-level costs. If you&#;re giving up customer valued performance or functions, you're trading market share and profitability for display savings and the net result may be decreased profit. The opposite also holds true; adding performance that is not necessary (these are attributes that the customer does not value) simply adds additional product costs.


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.

5 Advantages of Liquid-Crystal Displays (LCDs)

Featuring pixels made of liquid organic material, liquid-crystal displays (LCDs) are found virtually everywhere. They are used in homes, offices, schools, manufacturing facilities and even automobiles. Being that there are several other display technologies available, though, you might be wondering why LCDs are so popular. Here are the top five advantages offered by LCD technology.

#1) Energy Efficient

LCDs are known for their energy-efficient properties. They still require power to illuminate their respective pixels, but LCDs consume less power than non-LCD devices. When compared to cathode-ray tube (CRT), for example, a typical LCD will use about 25% less power. As a result, LCDs offer cost-savings benefits in the form of cheaper utility bills. You&#;ll pay less in utility expenses if you choose an LCD over a non-LCD device, making it a smart investment.

#2) Long-Lasting

Another advantage of LCDs is their ability to last for a very long time. LCDs typically don&#;t last forever, but they have a longer lifespan than that of other display devices. A typical LCD may last for up to 60,000 hours. Depending on how frequently you use it, that may translate into 20 or more years of usage. CRT displays, on the other hand, have a much shorter lifespan.

#3) LED Backlighting

LCDs support backlighting with light-emitting diode (LED). LED, in fact, is the most common type of backlighting used in their construction. To illuminate their respective pixels, LCDs need backlighting. LED backlighting has become the preferred choice among manufacturers because it&#;s both effective and energy efficient. The LED bulbs are placed in the back of the LCD where they illuminate the liquid pixels from behind.

#4) No Screen Burn-In

You don&#;t have to worry about screen burn-in with LCDs. Screen burn-in is a phenomenon that only occurs in display devices with phosphor-based pixels. Traditional CRTs fall under this category because their pixels are made of phosphor compounds. LCDs, however, use pixels made of organic material, so they don&#;t suffer from screen burn-in. You can leave a static image on an LCD for multiple consecutive hours without fear of it &#;burning&#; into the display.

#5) Supports Small and Low-Profile Sizes

LCD devices come in all shapes and sizes. While some of them are large, others are small with a narrow and low-profile design. Smartphones and tablets, for example, often use LCD technology. It allows for small and low-profile designs that isn&#;t possible with other, older display technologies.
