How to Choose the Right Components for LCM

As the time goes fast, we have seen many technological improvements in the display space such as TN, FSTN, and TFT LCD displays, thereby giving us a multitude of choices. We have also seen functionality enhancements.
In this fast-paced world with so many technological improvements, it can be difficult to understand the benefits of each type of display. Far too often, a display type becomes the buzzword of the year and everyone wants it for his or her product without a true understanding of the technology and its pros and cons. Do we really take the time to understand what we need or are we too consumed with the big picture to spend time on the details early on?
All too often, companies end up specifying a particular display without understanding whether other options may be better suited to their needs. This is because they haven’t thoroughly evaluated the end user’s expectations and instead make assumptions based on what they think is best – resulting in over-engineered or under-performing products. This has great implications on cost, design cycles and – potentially – user experience. Optical bonding of cover lenses is one example of this mistake. While it sounds like a must have it may not always be required.
The questions need to ask before engaging in a display project are:
l What type and size of display do I need?
lDo I need a reflective or transmissive display?
lWhat functionality am I expecting?
lWhat resolution is required to meet current and future needs?
lHow many years do I plan to continue making this product?
lWhat type of interface is required?
lWhat level of backlight brightness do I need?
lDoes my display module need a touch panel?
lWhat is my operating temperature range?
lDo I need an extra layer of protection from a glass cover lens?
The above list is not a complete list of questions, but food for thought – enough to get the design process moving on solid ground. These basic questions help display module manufacturers quickly whittle down the choices to a handful. This does not mean that further adjustments are not required, but it makes the process of choosing the correct display smoother and less cumbersome.
