Embodiment 1
Fig. 1 is the structural schematic diagram of the virtual reality device of the embodiment of the present invention, as shown in Figure 1.
The embodiment of the invention provides a kind of virtual reality devices, comprising: screen 10, backlight control component 20 and controller
30.Wherein, mark is stored in screen 10.Backlight control component 20 is connect with screen 10, and the setting for receiving screen 10 is drawn
The electrical parameter of foot output, and the backlight drive electric current to the output adaptation of screen 10.Controller 30 and screen 10 and backlight control
Component 20 connects.Wherein, controller 30 is for reading mark and electrical parameter, according to mark and electrical parameter, the class of recognition screen 10
Type.According to the type of screen 10, runs corresponding screen driver and control backlight control component 20 and fitted to the output of screen 10
The backlight drive electric current matched.
Technical solution provided in an embodiment of the present invention, controller 30 is according to the mark of the screen got and the setting of screen
The electrical parameter of pin output, determines the type of screen 10.According to the type of screen 10, runs corresponding screen driver and control
The backlight drive electric current that backlight control component 20 processed is adapted to the output of screen 10, thus in such a way that software and hardware combines, it is full
The demand of the compatible a variety of screens 10 of sufficient virtual reality device.A variety of screens can not only be switched in the development phase of product early period
10 verify to carry out the research and development of product, can also directly replace the screen 10 of different size in the different editions that product appears on the market,
Effectively reduce the version management cost of research and development cost and finished product.
Virtual reality device provided in an embodiment of the present invention is further detailed below.
For example, referring to fig. 2, controller 30 is as follows according to the mode of mark and the type of electrical parameter recognition screen 10:
Virtual reality device is after bringing into operation, firstly, controller 30 judges whether the screen 10 of access has identified
Its type.In the embodiment of the present invention, default screen 10 unidentified type, controller 30 out need to actively go to read when just bringing into operation
The mark of screen 10 is taken, mark includes but is not limited to for identification code.Controller 30 sends the instruction for reading mark to screen 10, from
After the mark for obtaining return in screen 10, it is stored in the program of controller 30.Meanwhile the setting of the acquisition screen 10 of controller 30 is drawn
The electrical parameter of foot output.Controller 30 determines the type of the screen 10 of access according to the mark and electrical parameter got.According to mark
Know and electrical parameter represent screen 10, controller 30 run corresponding screen driver and control backlight control component 20 to
The backlight drive electric current of the output adaptation of screen 10.
Referring to Fig. 3, in a kind of achievable embodiment of the invention, backlight control component 20 includes backlight control chip 21

The second end ground connection of resistance 223.
For example, it is connected between screen 10 and backlight control chip 21 by adjusting circuit 22, backlight control chip 21
Third pin obtain different level informations according to the different resistance values for the adjusting circuit 22 being connected thereto, thus to screen 10
Backlight drive electric current incoming end export different backlight drive electric currents.The level that different screens 10 passes through setting pin output
Difference, the grid of metal-oxide-semiconductor 225 realize the conducting situation between source electrode and drain electrode, to change according to the level height received
Access the difference of the resistance value of the third pin of backlight control chip 21.For example, screen 10 exports high level by setting pin,
Then the source electrode and drain electrode conducting of metal-oxide-semiconductor 225, the resistance value being connected on the third pin of backlight control chip 21 are second resistance
222 resistance value.Screen 10 exports low level by setting pin, then the source electrode and drain electrode of metal-oxide-semiconductor 225 is not turned on, and is connected to
Resistance value on the third pin of backlight control chip 21 is the sum of the resistance value of second resistance 222 plus 3rd resistor 223.Pass through
This mode adjusts circuit 22 according to the varying level value received, adjusts the resistance value of itself, so as to adjust access backlight control
The resistance value of the third pin of coremaking piece 21.Backlight control chip 21 is according to the different resistance value meetings being connected on third pin
Accordingly obtain different level informations.By the above-mentioned means, hardware can be obtained when the virtual reality device a variety of screens 10 of compatibility
Upper support.
