    • The present invention provides a liquid crystal display device capable of shortening the time required for stabilizing the brightness and the chromaticity to the temperature change. The input of an LED driver is connected to the output of a PWM controller, so that the electric power supplied to the respective LED groups of red, green and blue are controlled with a PWM method. A feedback control means for controlling the PWM controller includes a brightness setting means, a color setting means, a multiplication means for receiving the outputs from the brightness setting means and the color setting means, a comparison means fed with the output of the multiplication means at one of the inputs thereof, a light sensor temperature compensation means for compensating for fluctuations of the output of the light detection means due to temperature changes, a liquid crystal display panel temperature compensation means for compensating for fluctuations of the spectral transmittance of the liquid crystal display panel due to temperature changes, an addition means for summing the result of detection by the light detection means and the output of the light sensor temperature compensation means, and a multiplication means for multiplying the output of the addition means by the output of the liquid crystal display panel temperature compensation means.

    • A network system of the present invention includes a switch and a controller. The controller sets a flow entry, in which are defined a rule and an action used to uniformly control a packet as a flow, in a flow table of the switch. The switch determines whether or not to perform a sampling processing to a received packet, in accordance with the flow table setting, and notifies the controller of a sampling result in a case where a sampling processing is performed to the received packet. The controller updates the flow table in accordance with the sampling result and narrows packets to perform a sampling processing.
    • 本发明的网络系统包括开关和控制器。 控制器设置一个流条目,其中定义了一个规则和动作,用于在交换机的流表中统一控制数据包的流量。 交换机根据流表设置确定是否对接收到的分组执行采样处理,并且在对所接收的分组进行采样处理的情况下通知控制器采样结果。 控制器根据采样结果更新流表,缩小数据包进行采样处理。
