Background technology
Image source is the significant components of display.In order to increase the brightness of image source, it will usually it is realized by circuit adjusting, this
The power of image source can be caused to increase, so as to make the heat that image source generates more, temperature is excessively high, and then Thermal protection phenomenon, shadow occurs
Ring the normal work of display.This problem becomes apparent in digital image source, digital image source there are brightness it is low the shortcomings that.One
As, in order to which the brightness for improving digital image source is required for increasing circuit adjusting.
At present, the image source heat dissipation of display is radiated by way of natural heat dissipation.Image source is in closed space,
What the heat transfer of image source was mainly transmitted by contact of the image source housing with display housing.But image source housing and display shell
There are the adiabatic High molecular polymers such as gasket and position adjusting washer between body, this cause image source housing and display housing it
Between thermal contact resistance it is very big, this can so that the heat of the image source housing temperature when being difficult to pass is excessively high.And due to contact
The various parameters such as pressure, sealing mat thickness, washer quantity are inconsistent between different displays, this variation zone that will lead to thermal resistance
Between it is larger, the unstability of the thermal resistance of heat transfer path will be caused.
