    • There are provided a vacuum chamber system of a coating apparatus and a coating method using the same that prevents the attraction phenomenon of a coating solution in intermittent coating, so that the failure rate of coating is reduced, thereby improving the quality of products. In one embodiment, a vacuum chamber system of a coating apparatus includes a vacuum chamber connected to a coating solution outlet of the coating apparatus. A sound pressure generating unit is connected to one region of the vacuum chamber to generate sound pressure. A buffer tank is provided between the vacuum chamber and the sound pressure generating unit. In the vacuum chamber system, a control unit is further provided between the vacuum chamber and the buffer tank. The control unit controls air to be selectively inhaled or blocked from the vacuum chamber and the sound pressure generating unit.
    • 提供了一种涂覆装置的真空室系统和使用该真空室系统的涂覆方法,其防止了涂布溶液在间歇涂布中的吸引现象,从而降低了涂层的故障率,从而提高了产品的质量。 在一个实施例中,涂覆装置的真空室系统包括连接到涂布装置的涂布溶液出口的真空室。 声压产生单元连接到真空室的一个区域以产生声压。 在真空室和声压产生单元之间设置缓冲罐。 在真空室系统中,还在真空室和缓冲罐之间设置控制单元。 控制单元控制从真空室和声压产生单元选择性地吸入或阻挡空气。

    • A display apparatus and a control method thereof are disclosed. The display apparatus includes a signal processor which processes a video signal; a display which displays an image based on the video signal processed by the signal processor, a light source providing light for displaying the image; and a driving circuit which drives the light source on the basis of a dimming signal having an on-section and an off-section for dimming the light source. The driving circuit includes a protection circuit for performing a protection operation as a result of an abnormal electric current flowing in the light source during the off-section. The display apparatus is protected when a short circuit occurs between the light source and the driving circuit, thereby enhancing the stability and reliability of the apparatus.
    • 公开了一种显示装置及其控制方法。 显示装置包括处理视频信号的信号处理器; 基于由信号处理器处理的视频信号显示图像的显示器,提供用于显示图像的光的光源; 以及驱动电路,其基于具有用于使光源调光的截面和截止部分的调光信号驱动光源。 驱动电路包括保护电路,用于在断开期间由于在光源中流动的异常电流而执行保护操作。 当在光源和驱动电路之间发生短路时,显示装置被保护,从而提高了装置的稳定性和可靠性。
