  • Publication number: 20160028386
    Abstract: A delay circuit includes a current circuit, a first current mirror circuit, a second current mirror circuit, a self-compensation circuit, and a delay capacitor. A fixed ratio is between the first current and the second current provided by the current circuit. The first current mirror circuit generates a first mirror current in response to the first current. A partial current of the second current flowing through the second current mirror circuit is a base current, and the second current mirror circuit generates a second mirror current in response to the base current. The self-compensation circuit generates a feedback current in response to the second mirror current. The delay capacitor generates a delay signal. The charging current is equal to the second current subtracting the base current. The first mirror current is the sum of the base current, the second mirror current, and the feedback current.

  • Publication number: 20150314324
    Abstract: The present disclosure provides a sealant curing device and a mask plate thereof. The mask plate includes a light transmission region and a light shielding region. The light transmission region includes at least one through hole defined in the light transmission region. After the completion of exposing and curing sealant, at the beginning of the downward movement of the liquid crystal panel away from the mask plate, the presence of the through holes increases an area of air inlet, thereby increasing air inflow and reducing flow speed of intake air, so as to reduce a pressure difference of an air pressure between the mask plate and the liquid crystal panel and an air pressure of ambient air. Under conditions of same action area, a pressure force generated by the pressure difference and applied to the mask plate may be reduced, thereby reducing load for adsorbing the mask plate via vacuum.
