A method of fabricating a substrate for a display device prevents the problems occurring in the pattering process of a photosensitive organic material layer, such as the stage image transfer and mask image reflection. 16e standard and a channel estimator of the mobile terminal to which the method is applied. A hinge interconnects the parts. Also, a user can enter the dwell times for sample compounds and a buffer solution so that the system will alternatingly inject the sample compounds and buffer solution into a microfluidic device according to the specified dwell times. The method operates the IC in user mode. The method comprises the steps of: embodying Walsh patterns in a set of Walsh pattern matrices; processing groups of matrices from the set of Walsh pattern matrices to form a set of test matrices; mapping the set of test matrices to a test pattern set.
