Summary of the invention
The present invention is directed to the weak point of current needs and prior art development, provide all-in-one to power up the implementation method of display LOGO and sound brightness regulation.
All-in-one of the present invention powers up the implementation method of display LOGO and sound brightness regulation, the technical scheme solving the problems of the technologies described above employing is as follows: described all-in-one powers up the implementation method of display LOGO and sound brightness regulation, adopt in the all-in-one product of domestic CPU, before video card does not drive after power, by fpga chip at LVDS liquid crystal screen display product LOGO, to the experience that client is good; Its specific implementation process comprises: 1) in motherboard design, adopt fpga chip, converts the DVI signal that video card exports to corresponding signal, and is input in fpga chip by the signal after conversion; 2) simultaneously, the power supply electrifying sequential of fpga chip control system; 3) then, fpga chip, according to the corresponding signal of input and motherboard power supply signal, judges mainboard current state, 4) when fpga chip is judged as starting shooting but video card does not also have an initialization, fpga chip can export a secondary LOGO picture to display, some bright display.
Preferably, the DVI signal that video card exports is converted to 24 RGB digital signals and row field signal is input in fpga chip through SiI1161 chip.
Preferably, in step 4), after BIOS completes video card initialization, after video card has output, FPGA is by judging that the real content that video card exports then directly outputs on display by row field signal.
Preferably, produce pwm signal by response button and control LCD backlight, carry out the adjustment of display brightness; Pwm signal is produced to the control of the control realization of power amplifier to volume by response button.
Preferably, the control to other logics of mainboard is realized by other logic modules.
All-in-one of the present invention powers up the implementation method of display LOGO and sound brightness regulation, the beneficial effect compared with prior art had is: the present invention is in the all-in-one product of domestic CPU, adopt FPGA to realize all-in-one and power up rear video card initialization front display LOGO, and the adjustment realized screen intensity sound etc., improve user's user satisfaction, increase product competitiveness in the market, there is good development and application prospect.
figure of description:
Accompanying drawing 1 be integrated machine power up display LOGO and sound brightness regulation implementation method realize block diagram.
Embodiment
For making the object, technical solutions and advantages of the present invention clearly understand, below in conjunction with specific embodiment, the implementation method of the present invention kind of all-in-one being powered up to display LOGO and sound brightness regulation further describes.
In order to realize domestic processor all-in-one product power up after can Quick-Point bright display, do not allow the long times such as user, and the adjustment realized display brightness and volume, the present invention proposes the implementation method that all-in-one powers up display LOGO and sound brightness regulation, adopt in the all-in-one product of domestic CPU, before video card does not drive, by FPGA at LVDS liquid crystal screen display product LOGO, LOGO can be shown after powering up, to the experience that client is good, and in FPGA, realize the control to liquid crystal display brightness and system sounds volume.The present invention, by the mode of predicted point bright display, improves user's experience, judges mainboard different conditions by FPGA, realizes powering up display LOGO and controlling screen intensity and volume adjusting.
Embodiment:
All-in-one described in the present embodiment powers up the implementation method of display LOGO and sound brightness regulation, adopts FPGA to realize all-in-one and powers up rear video card initialization front display LOGO, and realize the adjustment to screen intensity sound etc.All-in-one described in the present embodiment powers up the implementation method of display LOGO and sound brightness regulation, its specific implementation process comprises: 1) in motherboard design, adopt fpga chip, convert the DVI signal that video card exports to corresponding signal, and the signal after conversion is input in fpga chip; 2) simultaneously, the power supply electrifying sequential of fpga chip control system; 3) then, fpga chip is according to the corresponding signal of input and motherboard power supply signal, judge mainboard current state, 4) when fpga chip is judged as starting shooting but video card does not also have an initialization, fpga chip can export a secondary LOGO picture to display, point bright display, realizes video card after powering and shows LOGO function over the display before not completing initialization.
All-in-one described in the present embodiment powers up the implementation method of display LOGO and sound brightness regulation, as shown in Figure 1, in the all-in-one product adopting domestic processor, convert 24 RGB digital signals to and row field signal is input in fpga chip by the DVI signal that exported by video card through SiI1161 chip.Described fpga chip, according to the row field signal of input and motherboard power supply signal, judges mainboard current state, and whether be that still video card of having started shooting also does not export, video card of still having started shooting has output, or does not have open state.
