Delivery

For more information, please visit LCD Manufacturer.

No matter what type of product you&#;re building, timely delivery of every component is critical. Even missing one part can bring an entire production to a grinding halt.

Here are some signs you might have a delivery problem on your hands:

• You&#;re not receiving delivery confirmations from your suppliers.
• There&#;s been an increase in variability with delivery times and/or missed commitments in terms of the delivery date.
• You don&#;t receive responses quickly (or at all) when you inquire about missed or late deliveries.

If this sounds familiar, we can help.

Obsolescence

Obsolescence happens when a part you use in your product design is no longer being made. If you manufacture a product long enough, you&#;ll almost certainly run into obsolescence at some point. Suppliers should get you this information as soon as it&#;s available so you can have enough time to come up with solutions before you&#;re in a bind but, unfortunately, this doesn&#;t always happen.

You might be facing obsolescence-based problems if:

• You&#;re in the middle of building a product and your supplier suddenly announces a part is no longer available.
• There has been a noticeable increase in the lead times associated with a particular component.
• You&#;re seeing an uptick in the prices of subcomponents that get passed on as a price increase for assembled parts.

Are you worried that one of your critical parts is becoming obsolete? We can help.

Quality

Quality refers to how well a part conforms to its design specifications. In other words, components are intended to work within certain tolerances, under certain conditions, for a certain lifespan. When they fail to fulfill those expectations, you have a quality problem.

The quality of your product might be suffering if you notice the following:

• An increase in out-of-the-box failures, which show up on your assembly line. This might look like a part that&#;s visibly damaged, or a part that&#;s been assembled into your product - then later is discovered to be incorrect.
• An increase in field failures, which are even more problematic for your business. These often show up once a product has been shipped to the end user, and then doesn&#;t work or stops working long before its life cycle should be over.

Are you experiencing these symptoms of quality problems? We can get you back on track!

Performance

Performance refers to the initial setting of the design specification for the product, and is different from quality. A product&#;s performance suffers when its design fails to contain all the functions and features the end user needs. It&#;s important to stay on top of performance issues, so you don&#;t end up lagging in the market.

Here are two major signs that you have problems in this area:

• You&#;re regularly hearing feedback from dissatisfied customers, which indicates your product should be better designed to meet their expectations.
• Your competition&#;s product has more features than yours does, which points toward a performance gap.

Struggling with performance? We can help you get your competitive advantage back.

Cost

Cost might be the last reason a manufacturer thinks about change, but it&#;s still an important factor. Keep in mind that the cost of your product is more than the sum of the components and labor that go into it. It also includes the indirect infrastructure supporting the labor and material management.

You might have a cost problem if:

• Your supplier has made an unexpected pricing increase.
• You encounter market resistance (this could suggest you&#;ve been paying too much from the beginning, and are consequently charging too much for your product).
• Your profitability has been slipping.

Stands for &#;Liquid Crystal Display.&#; LCD is a flat panel display technology commonly used in TVs and computer monitors. It is also used in screens for mobile devices, such as laptops, tablets, and smartphones.

LCD displays don&#;t just look different from bulky CRT (Cathode Ray Tube) monitors, the way they operate is significantly different as well. Instead of firing electrons at a glass screen, an LCD has a backlight that provides light source to individual pixels arranged in a rectangular grid. Each pixel has a RGB (Red, Green, and Blue) sub-pixel that can be turned on or off. When all of a pixel&#;s sub-pixels are turned off, it appears black.

 

When all the sub-pixels are turned on 100%, it appears white. By adjusting the individual levels of red, green, and blue light, millions of color combinations are obtained.

How LCDs are Constructed?

An LCD screen includes a thin layer of liquid crystal material sandwiched between two electrodes on glass substrates, with two polarizers on each side. A polarizer is an optical filter that lets light waves of a specific polarization pass through while blocking light waves of other polarizations. The electrodes need to be transparent, so the most popular material is ITO (Indium Tin Oxide).

As LCD can&#;t emit light itself, normally a backlight is placed behind an LCD screen in order to be seen during the dark environment. The light sources for backlight can be LED (Light Emitting Diode) or CCFL (Cold Cathode Fluorescent Lamps). The LED backlight is most popular.  Of course, if you like to have a color display, a layer of color filter can be made into an LCD cell. The color filter consists of RGB color. You can also add a touch panel in front of an LCD.

How LCDs Work?

The first LCD panel technology in mass production is called TN (Twisted Nematic). The principle behind the LCDs is that when an electrical field is not applied to the liquid crystal molecules, the molecules twist 90 degrees in the LCD cell. When the light either from ambient light or from the backlight passes through the first polarizer, the light is polarized and twisted with the liquid crystal molecular layer. When it reaches the second polarizer, it is blocked. The viewer sees the display is black.

When an electric field is applied to the liquid crystal molecules, they are untwisted.  When the polarized light reaches the layer of liquid crystal molecules, the light passes straight through without being twisted. When it reaches the second polarizer, it will also pass through, the viewer sees the display is bright.

Because LCD technology uses electric fields instead of electric current (electron passes through), it has low power consumption.
