Abstract: Pixels and sub-pixels suitable for high-density displays are disclosed. High-density is realized by forming a top-gate thin-film transistor (TFT) directly on top of a light-emitting diode (LED), thereby reducing the real estate required. To enable the stacked structure, a planarization layer is formed such that its top surface is coplanar with the top surface of the top electrode of the LED. The source and drain of the TFT are then formed on the planarization layer and electrode such that electrical contact is made between the LED and the TFT. In some embodiments, the fabrication includes deposition of an additional planarization layer whose top surface is coplanar with the top surface of the gate of the TFT. This enables formation of a parallel-plate capacitor on the TFT/LED stack, thereby reducing the footprint of the pixel even further.

Abstract: In a display apparatus, a frame rate converter divides an image signal into a first image frame for a left eye and a second image frame for a right eye, and generates a first intermediate image frame and a second intermediate image frame. A timing controller converts the first and second image frames to a first compensation frame and a second compensation frame, respectively, and sequentially provides the first compensation frame, the first intermediate image frame, the second compensation frame, and the second intermediate image frame to a data driver. The data driver converts the first and second compensation frames to left-eye and right-eye data voltages, respectively, and converts the first and second intermediate image frames to a predetermined black data voltage.

Abstract: A test pattern generator for generating test patterns for testing a servo circuit of a read/write head system. The pattern generator uses a relatively simple encoding technique to produce test patterns that have peaks with phase characteristics similar or identical to the phase characteristics of peaks of real data patterns, such as real BPS and sync mark patterns, for example, stored on a hard disk. The encoded data patterns are output to servo control logic to test the ability of the servo control logic to detect the patterns.
