Introduction to Display Technology
Display technology plays a critical role in how information is conveyed. Since its commercialization in 1922 up until the late 20th century, Cathode Ray Tube (CRT) has dominated the display industry. However, new trends such as the desire for mobile electronics have increased demand for displays that rival and surpass CRTs in areas such as picture quality, size, and power consumption. One such technology that has replaced the CRTs is Liquid Crystal Display (LCD) due to their lightweight, low operating power, and compact design. LCDs allowed devices such as digital watches, cell phones, laptops, and any small screened electronics to be possible. Although LCDs were initially created for handheld and portable devices, they have expanded into areas previously monopolized by CRTs such as computer monitors and televisions. Other contenders for leadership in display technology are Organic light emitting diode(OLED) and Plasma Display.

LCD Technology
LCD is an electronically-modulated optical device made up of any number of pixels filled with liquid crystals and arrayed in front of a light source (backlight) or reflector to produce images in color or monochrome.
There are 2 types of LCD displays (based on the circuits that are responsible for activating pixels).
An active matrix liquid crystal display (AMLCD) is a type of flat panel display, currently the overwhelming choice of notebook computer manufacturers, due to low weight, very good image quality, wide color gamut and response time. The most common example of an active matrix display contains, besides the polarizing sheets and cells of liquid crystal, a matrix of Thin film transistor(TFT) to make a TFT-LCD. These devices store the electrical state of each pixel on the display while all the other pixels are being updated. This method provides a much brighter, sharper display than a passive matrix of the same size. An important specification for these displays is their viewing-angle.
Twisted nematicdisplays contain liquid crystal elements which twist and untwist at varying degrees to allow light to pass through. A Super-twisted nematic(STN)display is a type of monochrome passive matrix LCD.STN displays provide more contrast than TN displays by twisting the molecules from 180 to 270 degrees. Film compensated Super-twisted nematic (FSTN) is a passive matrix LCD technology that uses a film compensating layer between the STN display and rear polarizer for added sharpness and contrast. It was used in laptops.
LCD Industry Overview
Global Market Size of Display Industry
- The revenue in 2008-09 and 2009-10 is decreasing, mainly due to recession.
- CAGR has been -1.74% due to the slump in 2008 to 2009.
- However, the market has been recovering at a steady pace, especially in 2010, with the revenue up by 10.86% from the previous year(2009).
- Pie chart depicts the revenue share of major technologies in the display market in 2010, which clearly indicates that TFT LCD is the leading technology and has maximum market share(92%) of the global display market.
Predicted future revenue of TFT LCD Market
After growing rapidly throughout the 2000s, industry revenues declined in both 2008 and 2009. While the immediate cause of this decline was the global recession, the display industry has also entered a mature phase. With notebook PCs and desktop monitors completely penetrated by TFT-LCDs, much of the growth in recent years has come from the TV market. Despite the recession, flat-panel-TV shipments grew on the order of 30% per year in 2008 and 2009. However, this growth is leading to high penetration rates, even in formerly emerging markets, such as China, and will push the flat-panel share of the TV market past 90% in 2011. This high penetration, combined with increasing pressure on prices, will lead to slower revenue growth, particularly for TFT-LCDs.
- The display market is dominated by TFT LCD but the growth of TFT LCD revenue would slow down in the years to come(2012-2016)
- But TFT LCD still would constitute more than 80% of the whole display market
- Future Technologies like AMOLED and 3D have a brighter chance to grow and yield revenues in the future

Model to measure market attractiveness
Market Attractiveness Model
Objective: This model can be used to study the attractiveness of a market and the various segments in the same. The model uses 3 parameters to measure the appeal of the market, namely:
- Market share:
Market size of each segment in the whole industry according to the revenue and the percentage share of each segment with respect to the whole industry. This is calculated for the current year in order to understand the current market size and share. - Compounded Annual Growth Rate (Forecasted for the next 6 years):
This year over year forecasted growth rate is taken as an indicator to show the future growth rate of each segment in the industry and hence its attractiveness in the future. - Competitors Strength:
This is the total market share captured by the top 3 players in each segment. This helps us in determining one of the entry barriers into the segment.
To analyze the model, Likert Scale Model has been used with the following ratings:
Each of the 3 parameters has been assigned the scale on different criteria’s (according to their nature), as given below:
For each parameter weights have been assigned as following:
- Market size: 40%
- CAGR: 40%
- Competitor Strength: 20%
Weights have been assigned in order to calculate the weighted average of the 3 parameters assigned to each segment, which would help us in determining one unit on the scale for each segment, which will help us in determining the attractiveness of each segment.
Market size and Forecasted CAGR have been assigned 40% weigh each as these are the two most important parameters which will help in determining whether a company should enter into that segment of the industry or not. Market size would give the revenue in the segment at present and also the percentage share each segment captures of the total Industry. CAGR would determine the growth rate of the revenue of each segment and hence would be profitable in the future or not.
Competitor strength is assigned 20% weight. We need to see how strongly or loosely is the segment held by the top 3 players of that particular segment. If it is tightly held then entry becomes difficult and similarly if loose, then there is huge unorganized sector or too many players in the market.
