    • A cooling device applied in a projection apparatus and the projection apparatus are provided. The projection apparatus comprises a first light source, a second light source, a third light source and the cooling device. The cooling device comprises an airflow guiding device and a fan. The airflow guiding device is adapted to define a first flow path and a second flow path. The first flow path has a first position, while the second flow path has a second position and a third position, correspondingly disposed with the first light source, the second light source and the third light source, respectively. The fan is adapted to generate airflow. The airflow is divided into a first airflow and a second airflow entering the first flow path and the second flow path, respectively. Thereby, the cooling device is capable of matching the heat dissipation requirements of the light sources and reducing the noise generated by the cooling device by using only one fan.
    • 设置在投影装置中的冷却装置和投影装置。 投影装置包括第一光源,第二光源,第三光源和冷却装置。 冷却装置包括气流引导装置和风扇。 气流引导装置适于限定第一流动路径和第二流动路径。 第一流路具有第一位置,而第二流路具有分别与第一光源,第二光源和第三光源相对应设置的第二位置和第三位置。 风扇适合产生气流。 气流分别分为进入第一流路和第二流路的第一气流和第二气流。 因此,冷却装置能够通过仅使用一个风扇来匹配光源的散热要求并降低由冷却装置产生的噪声。

    • A display device including a first voltage generator, a second voltage generator, a timing controller, a level shifter and a display panel is provided. The first voltage generator is configured to generate a gate high voltage. During a first period, the gate high voltage is a first voltage. After the first period, the gate high voltage is a second voltage. The first voltage is higher than the second voltage. The second voltage generator is configured to generate a gate low voltage. According to the gate high voltage and the gate low voltage, the level shifter shifts the voltage levels of the start signal, the clock signal and the inverse signal produced by the timing controller for driving a plurality of shift registers disposed on a substrate of the display panel. The shift registers is configured to output scanning signals in sequence.
    • 提供了包括第一电压发生器,第二电压发生器,定时控制器,电平转换器和显示面板的显示装置。 第一电压发生器被配置为产生栅极高电压。 在第一时段期间,栅极高电压是第一电压。 第一个周期后,栅极高电压是第二个电压。 第一电压高于第二电压。 第二电压发生器被配置为产生栅极低电压。 根据栅极高电压和栅极低电压,电平移位器移位由定时控制器产生的起始信号,时钟信号和反向信号的电压电平,用于驱动布置在显示器的基板上的多个移位寄存器 面板。 移位寄存器被配置为依次输出扫描信号。
