To identify the appropriate cluster of smart-phones which are likey to be launched with AMOLED screens
The two technologies can be compared on various attributes.
The radar graph here shows the comparison between OLED and TFT LCD.
The graph depicts the following things:
Sample Definition: The sample space consists of moblie phones by leading players in the smart-phone mobile category. These models were identified from Gartner reports. The models of smart-phones launched in the last three years in North America were considered.
Sample Space:After defining the sample, the various key attributes of smart-phones like camera, display, etc. were defined. The data for these attributes for all the models was collected from the company websites as well as the following websites:
The pricing information was obtained from
After aggregating the data we used the k-clustering method to identify the different clusters for the samples. This technique aims to partition n observations into k clusters in which each observation belongs to the cluster with the nearest mean. Hence clusters of phones with similar attributes is achieved.
Samples were segregated into two broad categories - candy-bar phones and clamshell or sliding phones - with thickness being the differentiating parameter. This was done in order to mitigate any error due to the design of the phone(i.e. candybar,clamshell,slider), since the thicknes of the mobile could be a cause for erroneous results.
The sheet below shows the clusters formed for the candy-bar phones.
The sheet below shows the cluster formed for the clamshell/sliding phones.
Definition of Attributes:
The matrices presented here show the common attributes for each cluster identified above and list the smart-phone models for each. The outliers are the models which could have fallen into some other cluster barring a particular attribute. This has been explained in the notes.
Candy-bar Phones
Clamshell/Sliding Phones
Using the analysis, one cluster of smart-phones likely to move to OLED technology was identified for each of the two categories. For the next stage of the research - that of forecasting sales of AMOLED display phones - would need the historical sales data of one particular model. For this purpose, Apple iPhone from the 2nd cluster of candy-bar phones was selected because of constraint of availabilty of sales data for other models like Blackberry, Nokia N96, HTC Dreamers etc.
Market data was collected for the prices of OLED screens by various manufacturers
