Problems solved by technology

[0004] When such a display is used for a camera, as the camera runs longer, the temperature inside the display will rise, and the fan inside the display will be automatically speeded up, and the sound of the fan running will often be received into the camera’s microphone, causing discomfort. Necessary interference, especially when a professional display equipped with a fan is installed in a SNG (Satellite News Gathering, satellite news broadcast vehicle) or broadcast studio, the sound of the scene is relatively small, and the sound of the fan in the display is particularly special at this time The prominence, the interference caused is also greater
It can be seen that the display temperature adjustment method in the prior art will make the sound of the fan in the display louder, causing interference

Embodiment 1

[0029] An embodiment of the present invention provides a method for adjusting the internal temperature of a display, the display is provided with a backlight source and a fan for cooling the display. The internal temperature adjustment method in this embodiment includes the step of silent mode, figure 1 It is a flow chart of a specific implementation of the silent mode steps.

[0030] see figure 1 , the silent mode steps include:

[0031] Step S101: start the silent mode;

[0032] In practice, the user can activate the mute mode of the display through a physical switch or an on screen display. For the scheme in which the user activates the mute mode of the display through a physical switch, a mode switch needs to be realized through hardware; for the scheme in which the user activates the mute mode of the display through the screen menu, the mode setting function interface needs to be implemented through software.

[0033] Step S102: controlling the speed of the fan in the...

Embodiment 2

[0066] Image 6 It is a block diagram of a partial structure of a display provided by another embodiment of the present invention, see Image 6 The display in this embodiment includes: a backlight 61 , a mode setting interface 62 , a fan 63 , a temperature detection unit 64 , a fan control unit 65 , and a backlight control unit 66 .

[0067] The backlight 61 provides backlight for the display.

[0068] The mode setting interface 62 is used to set the working mode of display temperature adjustment. In practice, the mode setting interface 62 may be a mode switch realized by hardware, or a mode setting function interface realized by software. In the case that the mode setting interface 62 is a mode switch realized by hardware, the user can set the working mode of display temperature adjustment through an actual physical switch; Users can set the working mode of display temperature adjustment through the screen menu.

[0069] Regardless of whether it is operated through a phys...

Abstract

The invention provides an internal temperature regulation method of a displayer and the displayer. A backlight and a fan dissipating heat for the displayer are arranged in the displayer. The method includes steps of a silent mode. The steps of the silent mode include starting the silent mode, controlling the rotation speed of the fan in the displayer to be reduced to a first preset speed value so that interference of fan operation sounds can be reduced, obtaining the internal temperature of the displayer, determining a target brightness value according to the internal temperature of the displayer and the corresponding relationship between a pre-stored temperature value and the target brightness value, and controlling the brightness of the backlight of the displayer to be reduced to the determined target brightness value. According to the corresponding relationship between the pre-stored temperature value and the target brightness value, the target brightness value is inclined to become smaller on the whole along with rising of the temperature. According to the technical scheme, normal operation of the displayer can be guaranteed, and meanwhile interference of the fan operation sounds is reduced.

Description

technical field [0001] The invention relates to the field of display control, in particular to a method for adjusting the internal temperature of a display and the display. Background technique [0002] The light-emitting elements in the display also generate high temperature while outputting light, so it is necessary to dissipate heat inside the display. In many monitors, fans are usually installed to facilitate more efficient cooling of the monitor. [0003] For example, the Taiwan Invention Patent Specification published on January 11, 2011 with the publication number TWI336008 discloses a liquid crystal display equipped with a fan and a method for adjusting its internal temperature. The liquid crystal display includes a backlight module and a cooling device A light source control unit is installed in the backlight module, and a fan, a fan control unit and a temperature sensing unit are installed in the heat dissipation device. In this solution, the temperature sensing ...
