Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a method for controlling a display screen timing sequence according to embodiment 1 of the present invention includes:
and S110, starting monitoring the clock state of the screen driving board.
Specifically, the clock state monitoring method may be implemented by detecting a power-on signal of a screen driving board of a display screen, and starting monitoring of the clock state of the screen driving board when the power-on signal of the screen driving board is detected, that is, when the power-on signal of the screen driving board is detected, and further, monitoring of the clock state is implemented by monitoring a LOCKN signal.
Preferably, a signal interface of the clock stabilization signal is connected to a main chip, and an IO port of the main chip monitors the clock state. In other cases, the clock state can be monitored through the self-contained function of the internal program of the display screen, and the beneficial effect of the invention is not influenced.
And S120, when the clock of the screen driving board is monitored to enter a stable state, transmitting the generated screen signal to the screen driving board, and starting a preset backlight delay at the same time.
For example, when the clock of the screen driving board enters a stable state, the clock stabilization signal, that is, the LOCKN signal may have a falling edge, and when the clock stabilization signal is monitored to have a falling edge, it is determined that the clock of the screen driving board enters a stable state, and transmission of the screen signal to the screen driving board is started.
Preferably, the screen signal is a signal transmitted according to the V-By-One standard.
It can be understood that when the clock of the panel driving board enters a stable state, the clock stable signal may also output other specific pulse information, such as a rising edge or an oscillation signal with a preset frequency, without affecting the beneficial effects achieved by the present invention.
And starting preset backlight delay for a control thread of the backlight plate by the screen driving plate at the same time of starting transmission of the screen signal. For example, the preset backlight delay presets a delay time length Ts through software, so that the time length Ts can be adjusted conveniently and high delay precision can be realized, when a clock of the screen driving board enters a stable state, the backlight delay is started, and the subsequent steps are executed by delaying the time length T. It can be understood that the backlight delay can also be realized by hardware delay, and the beneficial effects obtained by the invention are not influenced.
By way of example, the screen signal includes blank information and substantial information, such as regular screen information, where the substantial information is screen display start picture information and the like, and the blank information is blank screen information or blank screen information and the like before the substantial information. And in the transmission of the screen signal, sequentially transmitting the blank information and the substantial information, and if the duration of the blank information is Tb, adjusting the relationship between the time length Ts of the time delay and the duration Tb of the blank information according to the requirement. For example, when the essential information needs to be accurately displayed, Ts can be set to satisfy: ts ═ Tb, in other cases, such as where it is necessary to ensure that the substantive information is not missing, Ts may also be set to satisfy: ts is less than or equal to Tb, and the beneficial effects of the invention are not affected.
And S130, starting a backlight plate control signal to turn on the backlight plate when the backlight delay is finished.
And starting a control signal of a backlight plate, such as a control signal BLON of a conventional backlight plate, when the backlight delay is finished so as to turn on the backlight plate.
In the display screen timing control method provided in embodiment 1 of the present invention, the clock state of the screen driving board is obtained by monitoring the clock state of the screen driving board which is started and maintained; and when the clock of the screen drive board enters a stable state, starting transmission of a screen signal to the screen drive board, starting a preset backlight delay program, and after the backlight delay program is finished, starting a backlight board control signal to turn on a backlight board to complete time sequence control of the display screen. By monitoring the level change of the clock stabilization signal of the screen driving board, the clock stabilization signal is used as a transmission starting mark of the screen signal and a reference mark for opening the backlight plate, the problem of time sequence influence of power supply voltage on a display screen is solved, and the phenomenon that the screen is lost, the screen is blacked or information is omitted due to confusion between the time for opening the backlight plate and the time for starting the transmission of the screen signal is avoided. The stability of the chronogenesis of display screen and the suitability under different voltages have been improved, the user experience of display screen has been promoted simultaneously.
Referring to fig. 2, on the basis of embodiment 1, the method for controlling the timing sequence of the display screen according to embodiment 2 of the present invention achieves the effect of step S110 in embodiment 1 through the following steps:
and S111, when detecting that a screen driving plate of the display screen is electrified, starting monitoring of the working state of a clock data recovery circuit of the screen driving plate.
Specifically, when a screen driving board of the display screen is powered on, an HTPDN signal is generated to a main board, the HTPDN signal is associated with the clock data recovery circuit, and the working state of the clock data recovery circuit is monitored by detecting the HTPDN signal.
And S112, when the clock data recovery circuit is monitored to be in a normal working state, sending a clock signal to the screen driving board.
When the clock data recovery circuit is in a normal operating state, the HTPDN signal changes accordingly, for example, when the clock data recovery circuit operates normally, the HTPDN signal generates a falling edge, and when the falling edge of the HTPDN signal is detected, the motherboard is started to transmit the clock signal driven by the screen.
S113, when detecting that a screen driving board of the display screen is electrified, starting monitoring of the clock state of the screen driving board.
On the basis of obtaining the beneficial effects of embodiment 1, the method for controlling the time sequence of the display screen according to embodiment 2 of the present invention further monitors the state of the clock data recovery circuit before the clock signal is transmitted, and restarts the transmission of the clock signal when the clock data recovery circuit is normally operated, so as to ensure that the time sequence of the screen driving board is consistent with the time sequences of other circuits of the display screen in the subsequent signal transmission process, such as the transmission process of the screen signal, and improve the stability of signal transmission.
