Abstract: A device of gathering statistics of the gray distribution of an image and a method thereof are provided. The device includes a comparing unit, a count unit, a memory unit, and a data allotment unit. The comparing unit determines gray information of a plurality of gray data of the input image, and output a respective count signal accordingly. The count unit includes a plurality of counters. Each counter corresponding to predetermined gray information has a count value. The counters update the count values according to the respective count signals. When the count value exceeds a predetermined value, the count unit outputs a pulse signal corresponding to the predetermined gray information. The data allotment unit updates the statistics of the gray distribution of the image stored in the memory unit according to the pulse signal. The present invention reduces the number of the registers the counters require and decreases hardware costs.

Abstract: A wafer container includes a container body that having an open front on sidewall, a plurality of slots disposed in the container body for support wafers, and a door is assembled with opening of the container body for protecting the wafer therein, the characteristic in that: an recess is disposed in the inner surface, and a wafer restraint modules on the sides of the recess. The wafer restraint module includes a base portion for fixing the wafer restraint module on the platform, and a plurality of curve portions is formed on the side of the platform, in which each curve portion and the free ends constructed the protruding portion, thereby, the guiding notch of the protruding portion contacted the wafer to restrict the wafer from moving.

Abstract: A wafer container includes a container body with an opening on one side, and the inside with slots for placing the wafers. The door joined with the opening of the container body to protect the wafer therein, the characteristic in that: two rows of the plurality of wafer restraint components with a spaced at interval is located on the inner surface of the door and adjacent to the central of the door, in which the each wafer restraint component includes a base portion, which one end is fixed on the inner surface of the door, and another end is joined with a bent arm. The bent arm includes a first contact head and a second contact head to restrict the wafer moving toward the opening of the door.

Abstract: A wafer container includes a container body that having a plurality of slots therein for placing a plurality of wafers; an opening is formed on a sidewall of the container body for importing or exporting the wafers; and a door having an inner surface and an outer surface, in which the inner surface of the door is joined with the opening of the container body for protecting the plurality of wafers therein, the characteristic in that: a recess is disposed in the central portion of the inner surface of the door to divide the inner surface into two platforms, and each restraint module is located on two platforms.

Abstract: A driving device of a plasma display panel including a gray level arrangement unit, a still frame detection unit and a gray level arrangement controller is provided. The gray level arrangement unit receives image data and arranges the image data according to different gray level arrangement rules. The still frame detection unit detects whether the image data is a still frame. The gray level arrangement controller is electrically connected to the still frame detection unit and the gray level arrangement unit, and controls the gray level arrangement unit to output the image data with different gray level arrangements according to whether the image data is a still frame or not. A driving method of a plasma display panel is also provided.

Abstract: An apparatus for driving an interlaced plasma display panel (PDP), including a delay device, an image upper and lower edge detection device, an image border processing device, an image processing and analog control loop. The delay device receives an image signal, delays the image signal for two fields and outputs the delayed image signal. The image upper and lower edge detection device receives and analyzes the image signal, outputs the image upper and lower edge positions, saves and provides the odd field upper and lower edge data of the image signal. The image border processing device outputs the image signal after border processing according to the delayed image signal, the image upper and lower edge positions, the odd field upper and lower data. The image processing and analog control loop outputs a driving signal according to the image signal after border processing and the image upper and lower edge positions.

Abstract: A driving method and a driving circuit of a plasma display panel are provided. The driving circuit comprises a calculating unit, a gain unit, and a control unit, wherein the calculating unit is used for receiving an image signal to output a first display loading corresponding to the image signal. The gain unit is used for receiving the first display loading and by multiplying the first display loading with a gain constant, and then a second display loading is outputted. Furthermore, the control unit is used for receiving the second display loading to correspondingly output a sustain frequency. The power consumption of the plasma display panel is conformed to a rated value by driving with the sustain frequency.
