Abstract: An organic light emission display module is formed by an organic light emission device panel and a driving circuit board. In manufacturing the organic light emission device panel, electrodes are extended to the edges of the panel. The bonding pads are produced by forming aluminum films. The driving circuit board is made of thin printed circuit board, and bonding pads are manufactured at the edges of the printed circuit board, which are corresponding to the bonding pads of the organic light emission device panel, respectively. The driving circuit board is adhered to the organic light emission device panel, and the each bonding pad of the organic light emission device panel is connected to a respective bonding pad of the driving circuit board. Epoxy resin is filled into the bonding area and gaps between the printed circuit board and the organic light emission device panel.

Abstract: An optical compensation arrangement using tilted-optical-axis compensation films with negative birefringence for low-twist-angle nematic liquid crystal cells to achieve better viewing angle characteristics than a regular 90.degree.-twist TN cell, with similar high contrast ratio and brightness as the regular TN cell near normal incidence at a comparable operating voltage.

Abstract: A liquid-crystal projection display system with higher efficiency is provided. The liquid-crystal projection display system comprises a double-layer square-pillar-like integrator, including an inner layer and an outer layer, having a polarization-separating thin film formed between the inner layer and the outer layer. The system also includes a converging light source for generating light converged at a point near one end surface of the double-layer square-pillar-like integrator, so that most light emitted from the light source enters the double-layer square-pillar-like integrator, and different polarized light is transmitted by being totally reflected off of surfaces of the inner layer and the outer layer respectively. A first lens is provided for forming real light spots on an image plane from virtual light spots formed by totally reflecting the different polarized light transmitted in the double-layer square-pillar-like integrator.
