    摘要: In a method for determining whether electronic charge has been accumulated on the inner surface of a cathode ray tube (10), at least one electron beam is generated within the cathode ray tube and is deflected so that it hits the inner surface of the funnel (14) of the cathode ray tube. The temperature of a portion of the cathode ray tube is measured and is compared with a reference temperature value. If the measured temperature is greater than or equal to the reference temperature, it is determined that the electronic charge has accumulated. If the measured temperature is below the reference temperature, then the electron beam or beams have become switched off and electronic charge may not have accumulated on the inner surface of the cathode ray tube.

    摘要: An organic light emitting diode display for removing a voltage which is charged into a gate electrode of a driving transistor before a current frame is changed to a next frame is disclosed. In the organic light emitting diode display, a display panel has a plurality of pixels that include an organic light emitting diode. A timing controller controls a driving timing of the inputted video data and controls a supply timing of a refresh voltage. A data driver converts a digital data which is outputted from the timing controller for a current frame into an analog data voltage to supply it to the pixels, and then supplies the refresh voltage to pixels which are selected among the pixels in accordance with a control of the timing controller. And a gate driver primarily supplies a scanning pulse for a first horizontal period of a current frame to select the pixels to be supplied with a data, and then secondarily supplies a scanning pulse for a second horizontal period of a current frame to select pixels to be supplied with the refresh voltage among the pixels in accordance with a control of the timing controller.

    摘要: Cathode-ray tube comprising an evacuated envelope including a viewing window and a viewing screen comprised of a mosaic of phosphor areas of different emission colors supported on the inner surface of the viewing window. Closely spaced from the screen is a shadow mask having two opposed major surfaces and an array of apertures therein registered with the phosphor areas of said screen. At least one of the major surfaces of the mask and the inner surface of said screen have surface means for effecting faster radiative heat transfer from the central portion of the mask than from peripheral portions of the mask.
