Embodiment Construction

[0028] To the course of work of the present invention, with reference to accompanying drawing, illustrate in detail as follows:

[0029] figure 2 It is a structural block diagram of the cooling fan driving system of the display device in the present invention, image 3 It is a flow chart of the driving method of the cooling fan driving system of the display device in the present invention.

[0030] The cooling fan driving system of the present invention is different from that of the conventional plasma TV PDP TV. In the previous cooling fan driving system, only one temperature sensor was installed in the display device, and the driving voltage of the cooling fan was adjusted according to the measured temperature level. In this system, each cooling fan Fr, Fl is equipped with an independent sensor and controller, and according to the temperature difference measured by the sensor and the setting state of the plasma TV, automatically control the driving mode of the cooling fan ...

Abstract

The invention relates to a driving method of a cooling fan driving system of the display, especially to a plasma TV set and the likeness display which can automatic control the driving direction of the fan and weather drive it by their level or vertical arranging condition. It comprises the following stages: measuring each cooling fan temperature in the display, computing the temperature differential of the fans and comparing the temperature differential with the arranged condition critical value of the display, quoting weather the display arranged condition is level or vertical by the comparing result and controlling the driving fan and the driving direction.

Description

technical field [0001] The present invention relates to a driving method for a cooling fan driving system of a display device, and in particular to a method for automatically controlling the driving direction and direction of the fan in a plasma TV and similar display devices according to their horizontal or vertical setting state. Whether to drive, thus, reduce losses and improve cooling efficiency. Background technique [0002] A display device refers to a device that displays video information in the form of text or images through a picture tube. [0003] Its types include picture tube display devices, memory displays, plasma displays (Plasma Display Panel), liquid crystals, electroluminescence (Electro Luminescence), light emitting diodes, electrochemical displays (Electro Chromic Display) and the like. [0004] Among them, the plasma display (Plasma Dsplay Panel) is a wall-mounted display device with an ultra-thin picture tube. The light-emitting principle of plasma d...
