Display link driving type automatic horizontal screen control method and system

Technical Field

The invention relates to a display screen to transverse screen technology, in particular to a display link driving type automatic transverse screen control method and system.

Background

The existing display screen with display lightening drive, such as an LCD, is mainly displayed in a vertical screen arrangement mode, and for a rectangular display window with the proportion of 16: 9 and the like, characters or pictures displayed by the vertical screen display are small and are not easy to clearly observe, so that horizontal screen display is a better choice. However, the conventional vertical screen and horizontal screen rotating mode is mostly manually set, which is not convenient, so that the prior art has defects and needs further improvement.

Disclosure of Invention

Aiming at the problems in the prior art, the invention provides a Displaylink driving type automatic horizontal screen control method and system.

In order to achieve the above object, firstly, the invention provides a Displaylink driving type automatic horizontal screen control method, which has the following specific technical scheme: a Displaylink driving type automatic horizontal screen control method comprises the following steps:

s1: detecting whether a display screen is inserted into the system, if so, entering the next step, and if not, circularly detecting whether the display screen is inserted into the system;

s2: acquiring a rotation angle to be displayed in a display screen;

s3: and rotating the angle of the display contents in the display screen according to the rotation angle of S2.

Preferably, the step S4 is followed by a step S5: the detection process is terminated if the detection process is exited, and the process proceeds to step S2 if the detection process is not exited.

Preferably, the display screens are both LCDs.

Preferably, the step S1 is preceded by the step S0: and detecting whether the system is inserted into the encryption equipment, if so, entering the next step, and if not, circularly detecting whether the encryption equipment is inserted.

Secondly, the invention also provides a Displaylink driving type automatic transverse screen control system, which has the following specific technical scheme: a Displaylink driving type automatic transverse screen control system comprises:

a vertical screen;

the display main board drives the vertical screen to be lightened; wherein the Displaylink mainboard comprises an angle control program, and the angle control program comprises:

the angle setting unit is used for initially setting the rotation angle of the display content of the vertical screen;

an angle acquisition unit that acquires an initially set rotation angle of the angle setting unit;

and the angle display unit displays contents on the vertical screen according to the rotation angle fed back by the angle acquisition unit.

By adopting the technical scheme, the invention can realize automatic detection of the accessed display screen and transverse screen display of the accessed display screen, avoids the complexity of manual setting, and has extremely high efficiency particularly when multiple display screens are accessed.

Detailed Description

The invention is further described below with reference to the following figures and specific examples.

Referring to fig. 1, the present invention provides a Displaylink driving type automatic landscape control method, which specifically includes the following steps:

s1: detecting whether the system is inserted into the display screen, if so, entering the next step, and if not, circularly detecting whether the display screen is inserted into the system

In this step, if the display screen is not detected, the similar operations are performed, and step S1 is repeated until the system is detected that the display screen is inserted, and the next step is performed.

S2: obtaining the rotation angle to be displayed in the display screen

The control chip of the system may preset a rotation angle, such as 45 °, 90 °, 180 °, and the like, and the preferred angle in this application is 90 °.

S3: rotating the angle of the display contents in the display screen according to the rotation angle of S2

And rotating the color screen color content by the relevant angle according to the preset rotation angle in the step S2.

S4: detecting whether the program exits, if yes, ending, if no, proceeding to step S2

The step is a preferable step, and after the screen is horizontally arranged, if no other operation exists, if a plurality of display screens need to be accessed, the control method completes the operation and quits the system; if two or more display screens need to be accessed, the control method will continue to detect whether a new display screen is inserted, i.e. step S1 is entered for the next round of circulation.

Preferably, the step S1 is preceded by the step S0: detecting whether the system is inserted into the encryption equipment, if so, entering the next step

The system starts or starts the process and then proceeds to step S1, where if no encryption device is inserted, the process is repeated at a certain time interval (e.g., 1S), and step S1 is repeated until an encryption device is detected. The flowchart of the IC encryption firmware is shown in fig. 2, and specifically includes the following steps:

s001: initializing the USB after the equipment is powered on;

s002: reporting USB enumeration information;

s003: acquiring a PC instruction;

s004: judging whether the command is a command for setting a public key, if so, entering step S005, and if not, entering step S006;

s005: storing the public key command into the RAM, feeding back OK to the PC, and returning to the step S003;

s006: judging whether the command is a command for setting a communication key, if so, entering step S007, and if not, entering step S008;

s007: decrypting the communication key by using the public key, storing the decrypted communication key into the RAM, feeding back OK to the PC, and returning to the step S003;

s008: judging whether the command is a command for acquiring decrypted data, if so, entering step S009, and if not, entering step S010;

s009: decrypting the data by using the communication key, feeding the decrypted data back to the PC, and returning to the step S003;

s010: the feedback does not recognize the command to the PC, and returns to step S003.
