Description
Technical field
The present invention relates to OLED field of television, particularly relate to a kind of can the OLED display screen Circuits System of local display.
Background technology
In recent years, along with the further development of oled panel technology, oled panel production technology has tended to ripe, OLED face
Plate price is greatly reduced, and each television manufacturer the most progressively strengthens the exploitation of OLED TV.Oled panel itself has self luminous
Unique advantage, when screen display black picture, the LED on the correspondence oled panel of black field can completely close, higher to realize
Contrast and lower energy consumption.
The further lifting of television set intelligently, the addition of more software functions, cause OLED television startup speed increasingly
Slowly, for solving this problem, each television manufacturer successively adds sleep mode, when user has pressed Power key in OLED TV
After make OLED TV enter resting state, after pressing Power key again next time, TV is waken up, it is achieved the purpose of quick turn-on.Each product
The ins and outs difference of board OLED TV park mode, but general thought is all by closing OLED face in the hibernation mode
Plate is powered and is made TV enter dormancy.
Under existing park mode, OLED TV motherboard is in normal operating conditions, only closes oled panel and powers,
The power supply of OLED TV, mainboard and other parts module still in normal operating conditions, but due to after OLED TV dormancy shield
Curtain display blank screen, causes the park mode of OLED TV and is underutilized, also result in the wave of resource and the energy simultaneously
Take.
Summary of the invention
For prior art exist weak point, it is an object of the invention to provide a kind of can local display OLED show
Display screen Circuits System, can show the OLED display screen of the normal display function in region by achievement unit split screen, when OLED TV enters park mode,
The essential informations such as the often aobvious region of OLED display screen can serve as showing date, time, weather.
The purpose of the present invention is achieved through the following technical solutions:
A kind of can the OLED display screen Circuits System of local display, control mould including OLED display screen, power supply, the most aobvious OLED
Block and show very much control module, it is normal that the screen display region of described OLED display screen is often shown region, the second OLED screen by the first OLED screen
Aobvious region, the 3rd OLED screen often show region and OLED screen shows region composition very much, and described power supply electrically connects with OLED control module,
Described OLED control module respectively with often aobvious OLED control module, very show control module and electrically connect, described OLED control module
For being switched on or switched off and often showing the circuit that OLED control module electrically connects, described OLED control module be used for being switched on or switched off with
Show very much the circuit of control module electrical connection；Described OLED control module electrically connects with OLED tv state module, OLED TV
Block of state is for monitoring and tell the normal boot-strap duty of OLED TV, off-mode, resting state three kinds work
Three kinds of work state informations are also transferred to OLED control module by state；The most aobvious described OLED control module often shows with first respectively

OLED screen often shows region the 1, second OLED screen and often shows region the 2, the 3rd OLED screen and often show region 3 and OLED screen shows region 4 all very much
Content is shown in screen；When OLED tv state module monitors and tell OLED TV be in off-mode time, OLED
Off-mode information is transmitted to OLED control module 11 by tv state module, and OLED control module 11 controls power supply 12 respectively
With often aobvious OLED control module 9, very show control module 8 circuit and disconnect, the such first the most aobvious the most aobvious control of control module 5, second
Molding block the 6, the 3rd often shows control module 7 and shows very much control module 8 all power-off work, and the first OLED screen often shows region 1, second
OLED screen often shows region the 2, the 3rd OLED screen and often shows region 3 and OLED screen shows region 4 all blank screens and do not shows in screen very much
Content；When OLED tv state module monitors and tell OLED TV be in resting state time, OLED tv state module
Transmitting sleep state information to OLED control module 11, OLED control module 11 controls power supply 12 and the most aobvious OLED control module
9 circuit ON, OLED control module 11 controls power supply 12 and disconnects with showing very much control module 8 circuit, the most aobvious control mould
Block 8 power-off works, first often the most aobvious control module 7 of the aobvious the most aobvious control module of control module 5, second the 6, the 3rd be all energized work,
OLED screen shows region 4 blank screen and does not show content in screen very much, and the first OLED screen often shows region the 1, second OLED screen and often shows
Region the 2, the 3rd OLED screen often shows region 3 and all shows content in screen.
As it is shown in figure 1, the screen display region of OLED display screen is divided into upper, middle and lower three row's screen display region group, often row screen display region
Group is made up of screen display region, three, left, center, right, i.e. the screen display region of OLED display screen is made up of nine screen display regions, middle row's screen display
Region group is followed successively by the first OLED screen from left to right and often shows region the 1, second OLED screen and often show region the 2, the 3rd OLED screen Chang Xianqu
Territory 3.
