Abstract: A liquid crystal display panel and a liquid crystal display device are disclosed. The liquid crystal display panel includes a color film substrate, an array substrate disposed to face the color film substrate, and a blue backlight disposed on a side of the array substrate away from the color film substrate. The color film substrate includes a base substrate, red quantum dot blocks, green quantum dot blocks and blue light blocks disposed on the substrate. The color film substrate further includes a yellow light layer disposed between the red quantum dot blocks and the base substrate, and also between the green quantum dot blocks and the base substrate. The yellow light layer in the liquid crystal display panel of the present disclosure may block blue light, thereby improving the color gamut value.

Abstract: A quantum-dot color filter substrate and a quantum-dot liquid crystal display panel are disclosed in the present disclosure. The quantum-dot color filter substrate includes a glass substrate and a quantum-dot light conversion layer formed on the glass substrate and including a plurality of quantum-dot parts arrayed in sequence, wherein the quantum-dot parts include a red quantum-dot part, a green quantum-dot part and a blue quantum-dot part, and the red quantum-dot part and the green quantum-dot part contain infrared quantum-dot materials. In this way, the purity of lights emitted by a color filter can be improved, and displays can be made light and thin.

Abstract: In a fan control method, consecutive temperature values are acquired at a time interval. Whether a current temperature value is higher than a threshold is determined. A difference between the current temperature value and a previous temperature value is calculated when the current temperature value is higher than the threshold. A fan is speeded up and the time interval is greatly shortened when the temperature difference is higher than a first trigger value. Only the time interval is slightly shorten when the temperature difference falls between the first trigger value and a second trigger value less than the first trigger value. Nothing to do when the temperature difference falls between the second trigger value and a third trigger value less than the third trigger value. The fan is slowed down and the time interval is extended when the temperature difference is lower than the third trigger value.
