  • Publication number: 20120300419
    Abstract: An intermediate structure of a flexible display device includes a substrate, an etching layer, a flexible substrate, and a display module. A trench structure is formed in a surface of the substrate. The etching layer is formed on the surface and covers the substrate. The flexible substrate is disposed on the etching layer. The flexible substrate and the substrate are spaced apart from each other by the etching layer. The display module is disposed on the flexible substrate. The flexible substrate can be peeled from the substrate without applying a mechanical force and thus the yield is improved, and the process time and the fabricating cost are also reduced. In addition, the present invention also provides a substrate for fabricating a flexible display device and a method for fabricating a flexible display device.

  • Publication number: 20120070984
    Abstract: In a method for forming an electrode structure in a display device, e.g. a source, drain or gate electrode or a pixel electrode, a photoactive conductive layer, which includes conductive material containing photoactive material, is formed above a substrate of the display device. The photoactive conductive layer is then patterned with a photo-mask and partially removed without the presence of a photo-resist to form the electrode structure.

  • Patent number: 7092054
    Abstract: The method for fabricating reflector plate for a reflective liquid crystal display and the device is disclosed. The present invention includes the formation of a protection layer over the glass substrate having thin film transistors and a layer of transparent electrodes on top, followed by the formation of a layer of undulating resin over the protection layer. If the reflector plate to be produced is a semi-transmissive type, a light-transmitting region is created over the protection layer. Since the protection layer is created in advance of the undulating resin outgrowth, the present method can effectively prevent reflection from the exposure stage during the lithography process, thus the problem of abnormal pattern marks occurring on the reflective surface can be avoided, and the exposure time and the production yield are enhanced.

  • Patent number: 6788363
    Abstract: A reflector structure in a multi-domain liquid crystal display comprises an active matrix device structure having regions of various height levels, a diffusing layer, and a structure of multi-domain reflective layer. The diffusing layer is formed above the active matrix device structure with multiple extruded bumps of various film thickness and various heights and shapes. The reflector structure has various reflective angles and reflective effects to improve the quality of LCD panel. It can be used in the reflective layer of a reflective or semi-reflective TN, STN, TFT, or TFD. The reflector fabrication process uses conventional process for a metal or an insulation layer on a TFT substrate to form multiple domains within a pixel area. After forming the cell structure of the multi-domain reflective layer, liquid crystal cells form multiple domains within a pixel area.
