  • Patent number: 7323217
    Abstract: An optical-interference type reflective panel and a method for making the same are disclosed, wherein the display panel has a substrate on which multiple supporting layers are firstly formed. Then, a plurality of first conductive optical film stacks, spacing layers and multiple second conductive optical film stacks are sequentially formed on the substrate. Finally, once the spacing layers are removed, optical-interference regulators are formed. Since said supporting layers forming step is prior to the first conductive optical film stacks, a precise back-side exposing step is not necessary so that the making procedure of the panel is simplified.

  • Publication number: 20080013241
    Abstract: A humidity detection and power cut-off device for electronic equipment is provided. The device is connected between a battery (10) and a motherboard (40) of the electronic equipment and includes an auto protection device (20) and a moisture-triggered device (30). The auto protection device is connected between the battery and the power management module and is used to establish or cut off the connection between the battery and the power management module. The moisture-triggered device is used to detect the immediate ambient humidity and controls the auto protection device. If the moisture-triggered circuit detects that the immediate ambient humidity exceeds a predetermined critical humidity value, the moisture-triggered device outputs a trigger signal to the auto protection device. The trigger signal controls the auto protection circuit to cut off a connection between the battery and the power management module, thus to achieve waterproofing protecting for the electronic equipment.

  • 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.

  • Publication number: 20060177950
    Abstract: The method of manufacturing an optical interference color display is described. A first electrode structure is formed over a substrate first. At least one first area, second area and third area are defined on the first electrode structure. A first sacrificial layer is formed over the first electrode structure of the first area, the second area and the third area. Moreover, a second sacrificial layer is formed over the first sacrificial layer inside the second area and the third area. In addition, a third sacrificial layer is formed over the second sacrificial layer inside the third area. The etching rates of all sacrificial layers are different. Then, a patterned support layer is formed over the first electrode structure. Next, a second electrode layer is formed and the sacrificial layers are removed to form air gaps. Therefore, the air gaps are effectively controlled by using the material having different etching rates.
