Abstract: Disclosed herein are an automatically replaceable apparatus for collecting byproducts in semiconductor producing equipment and a control method thereof. The apparatus includes several trap units mounted to a vertical shaft at regular angular intervals and rotating in response to a driving direction of a servo motor. Upper and lower plates support the vertical shaft, and connect byproduct inlet and outlet ports, cleaning-water supply and discharge ports, and dry-gas supply and exhaust ports to the respective trap units. Trap and plate coupling means are extended at normal times to air-tightly seal gaps between the upper and lower plates and the trap units, and contracted when the trap units are rotated in a predetermined direction for the replacement. The servo motor is mounted to a lower surface of the lower plate and rotates the trap units within a predetermined angular range. A control unit controls the operation of the components.

Abstract: An apparatus and method for revising video data for en electron emission display device to improve image quality by reducing non-uniformity in luminance of a plurality of pixels. In an exemplary embodiment, a display region includes a plurality of pixels, each pixel comprising at least one electron emission device. A scan driver and a data driver control the pixels through electrodes coupled to the display region. A revision coefficient unit is coupled to the display driver, for storing a plurality of revision coefficients, receiving and revising video data utilizing the revision coefficients, and sending revised video data to the data driver. The revision coefficients correspond to first average luminance values of first lines of pixels extending in a first direction, and second average luminance values of second lines of pixels extending in a second direction.
