The embodiment of the invention provides a webpage opening method and device and a terminal device, and belongs to the technical field of internet. The webpage opening method includes the following steps of generating and sending a webpage opening request for requesting the webpage content according to a triggering operation of a webpage link in a current interface, receiving the webpage content returned according to the webpage opening request, and displaying the webpage content through a floating window based on the current interface. Based on the method, after the link on the current webpage is clicked on, the content of the link is displayed to a user through the floating window of the current webpage, and the current webpage can not be closed; in other applications, after the user sees the link and clicks on the link, there is no need to skip to a browser application, and the frequent skipping between the APPs and the browser application is avoided for the user. Thus, the user experience is improved when the user opens a new link.

The invention relates to a temperature detecting device, a temperaure detecting method and a liquid crystal driving device. The temperature detecting device comprises a state machine, a frame frequency selection unit and a frame frequency output unit. When a current temperature value jumps around a certain critical temperature value, the state machine judges whether the difference value of the current temperature value and the critical temperature value is within the preset range; if the difference value of the current temperature value and the critical temperature value is within the preset range, the state machine determines that the current state is the previous state; if the difference value of the current temperature value and the critical temperature value is out of the preset range,the state machine determines that the current state is the state corresponding to the current temperature value. The frame frequency selection unit connected with the state machine is used for selecting the frame frequency corresponding to the current state according to the current state determined by the state machine. The frame frequency output unit connected with the frame frequency selectionunit is used for outputting the frame frequency. When the temperature jumps frequently in a smaller range, the temperature detecting device can avoid the frequent jump of the frame frequency and the flicker of a liquid crystal display screen caused by the frequent jump of the frame frequency, and thus the display quality of liquid crystal display screen is enhanced.
