It is led on backboard 40 on generated heat transfer radiator structure 100, such timing controller 50 generated heat when working
Amount conducting path has two, and the path conducted is short, and thus efficiently conduction controls the heat on chip 50, guarantees control core
The stable work of piece 50.In addition, pin is greater than the chip body side in the projected length perpendicular to timing controller 50
Length of the portion apart from circuit board 20, pin need to be welded on timing controller circuit board 20, and pin is perpendicular to timing control
The projected length of coremaking piece 50 is greater than length of the chip body side apart from circuit board 20, and such pin can not be welded on electricity
On road plate 20, and then it cannot achieve the function of control chip 50；Pin is big in the projected length perpendicular to timing controller 50
In length of the chip body side apart from circuit board 20, facilitate the welding of pin Yu timing controller circuit board 20；Separately
Outside, the pin of timing controller 50 is drawn from the aperture inner bending, interface corresponding with timing controller circuit board 20
It is electrically connected, in this way, the position that pin is drawn is also in aperture, institute because timing controller 50 is to sink to being placed in aperture
It is adopted with pin and is drawn in aperture inner bending, be then welded on pin on timing controller circuit board 20 and timing controller
Circuit board 20 is electrically connected, this ensure that timing controller 50 is using the same of radiating mode described in the utility model
When, good electric connection is still kept between timing controller circuit board 20.
As another embodiment of the utility model, refering to what is shown in Fig. 6, disclosing a kind of display device 140, the display
Device 140 includes above-mentioned display module 160.
In present specification, radiator structure can be the cooling fin 130 being made by silica gel, and cooling fin is equipped on one side
Glue, to paste control chip 50.Certainly, the radiator structure in the application can also on to be formed directly into control for thermal paste
On chip.
The panel of the utility model can be TN panel (full name is Twisted Nematic, i.e. twisted nematic panel),
IPS panel (In-PaneSwitcing, plane conversion), VA panel (Multi-domain Vertica Aignment, mostly elephant
Limit vertical orientation technology), it is of course also possible to be other kinds of panel, it is applicable in.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is only limited to these instructions.For the ordinary skill of the utility model technical field
For personnel, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made, should all regard
To belong to the protection scope of the utility model.
