Detailed Description of the Invention
In the current work, Olympus BX-50 optical Microscope, 10X Camera as well as MATLAB Software are required for image analysis technique. In order to overcome the problem of characterizing the display device parameters, distinct instrumental methods are required. To rectify such an issue a novelty in approaching the quality assessment of liquid crystal materials are being adopted in the current project work. Obtained values are compared with standard techniques for veracity point of view. With this current approach efficiency of 99% has been attained.
A homogeneous cell of dimensions 5mm × 5 mm with 6 μm spacing (tolerance ±0.2μm) which is been coated with indium–tin oxide, is to be filled with said liquid crystal sample and must place on the prism table of the Olympus BX-50 optical microscope. Now the back light is to be focused from the lower side and from the upper end the textures should be captured using high resolution digital camera. For further processing, the recorded textures are to be saved in a computer. Read the image from the database and convert it into matrix from using matlab software. Each and every element of the matrix has a value interrelated to the darkness/brightness of the pixel at the corresponding position or feature of an image. In Olympus-BX 50 microscope, generally U-Pot (polarizer) and U-Ant (analyzer) acts as an interference filters for estimation of display parameters.
Application of algorithms and computational techniques on image data is absolutely helpful in finding the discrete parameters of liquid crystals. Thus image analysis is the best method to extract the information from textures. In the current article, various significant parameters of the LC’s such as luminance, luminance uniformity, luminance contrast ratio, visual acuity, gray shades and contrast modulation. The mentioned parameters are deliberated with computational techniques on discrete liquid crystal textures. An image of the texture I(i, j) is of the size m-by-n which is a two dimensional function poised of ‘m’ pixels in the horizontal direction and ‘n’ pixels in the vertical direction and, i, j are horizontal and vertical coordinates of the image. The total number of pixels in the image are denoted with m∗n= N, 0 ≤ i ≤ m, 0 ≤ j ≤ n
The following steps are to be followed to determine the liquid crystal display devices: Step 1: Read the image and set the dimensions as 256x256; Step 2: Image data is to be store in file folder of PC; Step 3: Using Matlab software convert the image data into Red Blue Green image color data; Step 4: Transmitted Intensity is being represented by RGB color data which is the base for evaluating liquid crystal display devices; Step 5: Compute the luminance and its dependent parameters which is the base for liquid crystal display device using RGB intensities with variation of temperature; Step 6: Determine the quality of the liquid crystal for designing the display devices.

For validating the quality of the results obtained with image analysis technique are being correlated with data from other customized techniques like Luminance meter, Differential thermal analysis (DTA) method etc., The seized results are in good compliance with each other.
