  • BiNem$^{(R)}$ displays have entered volume manufacturing in 2009. Applications range from e-labels to e-readers. We have developed 6-inch $960{\times}720$ pixels passive matrix BiNem prototypes achieving 40 % brightness and fluid user interface based on partial image / dynamic pointer addressing. Active-matrix addressing is proposed to provide even faster operation.

  • A hardware architecture is presented of a wavelet based multiple line addressing driving scheme for passive matrix displays using the FPGA (Field Programmable Gate Arrays), which will be integrated in the scalable video coding $architecture^{[1]}$. The incoming compressed video data stream will then directly be transformed to the required column voltages by the hardware architecture without the need of employing the video decompression.

  • Organic light-emitting diode (OLED) display panel using the charge-pump (CP) pixel addressing scheme was fabricated, and the results show that it is applicable for information display. A CP-OLED panel with 64 ${\times}$ 64 pixels consisting of thin-film capacitors and amorphous silicon Schottky diodes was fabricated using conventional thin-film processes. The pixel drive circuit passes electrical current into the OLED cell during most of the frame period as in the thin-film transistor (TFT)-based active-matrix (AM) OLED displays. In this study, the panel was operated at a voltage level of below 4 V, and this operation voltage can be reduced by eliminating the overlap capacitance between the column bus line and the common electrode.

  • The charged particle type display is a kind of electronic paper showing information images using positive and negative charged particles ($<10{\mu}m$). In this work we used yellow(-) and black(+) particles which are respectively addressed to the cells of a upper and a rear substrate by using electric field. Our independent addressing method has strong points compared to the mixed particle putting method. The packaging with two orthogonal substrates and the aging process is followed by addressing process. The panel is sequentially driven by matrix method for each 4-unit cells. Layers of particles are controlled by barrier ribs and must be addressed to minimum 2 layers.

  • 대전입자형 디스플레이는 높은 대조비와 넓은 시야각 그리고 빠른 응답속도를 가졌다. 본 연구에서는 음전하를 띈 노란색 대전입자와 양전하를 띈 검은색 대전입자를 사용하여 화상을 표시하였으며, 기존의 혼합된 대전입자를 충전하는 방식과는 대비 패널의 상판과 하판에 형성된 셀에 두 대전입자를 전계에 의해 각각 어드레싱하였다. 그리고 상판과 하판을 합착한 후 Aging을 하여 패키징을 하였으며, 합착된 패널은 전극 설계에 의해 4 채널의 전극에 Matrix 구동을 했다. 패널에 충전되는 layer 수는 최소 2 layer가 요구되며, 본 연구에서는 대전입자의 layer는 격벽의 높이로 조절하였다. 패키징된 패널의 상판에 양의 전압을 인가한 결과, 노란색 대전입자는 상판의 전극으로 이동하고 검은색 대전입자는 하판의 전극으로 이동하였다.

  • Since 1992, Philips has been developing polymer OLEDs resulting in a first commercial monochrome display just 10 years later. Philips is now focusing on the technology development required to mass-produce full-color polymer OLDE displays, based on passive and active-matrix addressing. High precision inkjet printing has been chosen as the deposition technology for the OLED material. In this paper, we give an overview of the activities of Philips in the area of mobile OLED applications and explore the route towards large screen OLED television.

  • Organic field effect transistors are excellent candidates for addressing and local amplification elements for large area electronics because they can easily be processed at low temperatures on essentially arbitrary substrates. We present the use of these devices in an active matrix photodetector and as a buffer for a strain sensor.

  • Recent advances in linear programming solution methodology have focused on interior point methods. This powerful new class of methods achieves significant reductions in computer time for large linear programs and solves problems significantly larger than previously possible. These methods can be examined from points of Fiacco and McCormick's barrier method, Lagrangian duality, Newton's method, and others. This study presents a primal-dual log barrier algorithm of interior point methods for linear programming. The primal-dual log barrier method is currently the most efficient and successful variant of interior point methods. This paper also addresses a Cholesky factorization method of symmetric positive definite matrices arising in interior point methods. A special structure of the matrices, called supernode, is exploited to use computational techniques such as direct addressing and loop-unrolling. Two dense matrix handling techniques are also presented to handle dense columns of the original matrix A. The two techniques may minimize storage requirement for factor matrix L and a smaller number of arithmetic operations in the matrix L computation.
