Description
Technical field
The utility model is related to multihead display field, more particularly, to Double-Screen Display System.
Background technology
The mode integrated level realizing shuangping san now on the market is relatively low, with high costs.Its implementation mostly uses two
Set display system, often all includes power panel and signal plate (separate or unify) in set system.Wherein set of system is as master
Display screen, another set of system is as secondary display screen.Main display output image signal (form such as HDMI, VGA, DVI) arrives secondary aobvious
Display screen, secondary display screen and is being shown the signal transacting of main display by related circuit.It is interior that secondary display screen shows
Hold by main display control, this kind of implementation pair display screen is also required to a set of signal processing circuit, design redundancy, integrated level
Low, relatively low resource utilization increased cost.
Utility model content
The technical problems to be solved in the utility model is：A kind of Double-Screen Display System is provided, reduces the cost of shuangping san.
For solving the above problems, the technical solution adopted in the utility model is：Double-Screen Display System, including the first display
Screen, second display screen, power panel and signal plate, power panel is connected with signal plate, and described signal plate includes master chip, signal turns
Change chip, the first output end and the second output end, described signal conversion chip and described signal conversion chip, the first output end
Connect, described master chip is connected with described second output end, described first output end is connected with described first display screen, described the
Two output ends are connected with described second display screen.
Preferably, described power panel and signal plate are integrated into an integrated board.
One kind of the present utility model for electric connection mode is：Described power panel and described first display screen, second display screen
Between the larger display screen of power connect.
One kind of the present utility model for electric connection mode is：Described power panel includes the first power panel and second source plate,
Wherein, described first power panel is connected with described first display screen, and described second source plate is connected with described second display screen.
The beneficial effects of the utility model are：The utility model uses the signal plate of one piece of high integration, is provided with
Master chip, signal conversion chip, master chip output 1 road LCD (LVDS, MIPI, EDP etc.) signal and the non-LCD signal in 1 tunnel (HDMI,
VGA, DVI etc.) signal, non-LCD signal is converted into the signal of display screen LCD through signal conversion chip, therefore goes out from signal plate
The signal coming is that 2 roads drive the LCD signal of display screen it is achieved that a set of signal processing circuit drives two display screen effects, letter
Change the structure of system, reduce the cost of shuangping san.
Brief description
Fig. 1 is the first structural representation of embodiment；
Fig. 2 is the second structural representation of embodiment；
Fig. 3 is the third structural representation of embodiment；
Fig. 4 is the 4th kind of structural representation of embodiment；
Fig. 5 is the 5th kind of structural representation of embodiment.
Specific embodiment
Below by embodiment, the utility model is described further.
As shown in figure 1, embodiment includes main display, secondary display screen, power panel and signal plate, signal plate specifically includes
Master chip, signal conversion chip, the first output end and the second output end, the connected mode of embodiment is as shown in figure 1, signal turns
Change chip to be connected with signal conversion chip, the first output end, signal conversion chip is connected with the second output end, the first output end with
Main display connects, and described second output end is connected with described pair display screen.Wherein, master chip is full will A83T chip, its core
Piece has the ability (other chips such as Rk3288 chip also has this function) of output 1 road LVDS and 1 road HDMI signal in itself；Letter
Number conversion chip is LT8619B chip, is converted into LVDS signal for the HDMI signal out by master chip.Therefore signal plate energy
Enough directly output 2 road LVDS signals, direct drive main display and secondary display screen liquid-crystalline glasses.
For ease of installing, dismantling, as shown in Fig. 2 power panel and signal plate are integrated into an integrated board by this example.By one
Body plate carries out signal output and power supply to two display screens.Of course, those skilled in the art can not also be by power panel and letter
Number plate is integrated into an integrated board, from the angle that power supply is powered, the utility model is further illustrated below, power panel therein
An integrated board can be integrated into signal plate it is also possible to power panel and signal plate are not integrated into an integrated board.
When two display screen power are less, it is possible to use it is directly two displays that the power supply interface of signal plate is directly powered
Screen is powered, and is that signal plate is powered with a power panel, this measure can eliminate a power panel, further saves into simultaneously
This.
When a display backlight power is big, a display backlight power hour, as shown in Figure 3, it is possible to use signal
The power supply interface of plate is directly powered for lower-powered main display, and the first power panel is respectively signal, second source plate
For the secondary display screen back of the body power supply that luminous power is larger.
When two display backlight power all than larger when, as shown in Figure 4, it is possible to use two power panels are respectively two
The display screen back of the body is powered, and that is, the first power panel shown in figure is connected with main display, and second source plate is with secondary display screen even
Connect.
When two display backlight power all than larger when, as shown in figure 5, can also use a relatively high power power supply
Respectively signal plate, main display, secondary display screen is powered plate simultaneously.
It is pointed out that some principles of the present utility model that simply explain through diagrams described above, due to identical skill
It is easy to for the those of ordinary skill in art field carry out some modifications on this basis and change.Therefore, this specification
Be not intended to by the utility model be confined to shown in and described concrete structure and the scope of application in, therefore every be possible to sharp
Corresponding modification and equivalent, belong to the apllied the scope of the claims of the utility model.
