Embodiment 1
[0051] Such as figure 1 As shown, a dual-screen display system includes: a main display device 1 and an extended display device 2. The main display device 1 includes a main display screen 11, a drive unit 12, a first control unit 13, and an HDMI output interface 14. The extended display device 2 includes an extended display screen 21, an input interface 22 and a second control unit 23, among which,
[0052] The driving unit 12 is used to generate a first driving signal, where the first driving signal is used to determine whether to drive the extended display screen 21 to adjust the brightness;
[0053] The first control unit 13 is connected to the drive unit 12, and is used to receive the first drive signal output by the drive unit 12, and when it is determined that the first drive signal satisfies the brightness adjustment condition for adjusting the brightness of the extended display screen 21, Generate a brightness adjustment signal, and output the brightness adjustment signal t...
Embodiment 2
[0083] Such as Image 6 As shown, a dual-screen display method of the above-mentioned dual-screen display system includes the following steps:
[0084] Step S11, generating a first driving signal;
[0085] Step S12, determining whether to drive the brightness adjustment of the extended display screen 21 according to the first driving signal. Wherein, if yes, go to step S13; otherwise, end the process of adjusting the brightness of the extended display screen 21 driven by the first driving signal. This step is Image 6 Not shown in.
[0086] Step S13, generating a brightness adjustment signal;
[0087] Step S14, output the image data to be played and the generated brightness adjustment signal to the input interface 22 in the dual-screen display system, so that the input interface 22 sends the received brightness adjustment signal to the second control unit 23 in the dual-screen display system ;
[0088] Step S15: After receiving the brightness adjustment signal, the second control unit...

Abstract
The invention provides a double-screen display method and system and relates to the technical field of double-screen display. The system comprises a master display device and an expanded display device. The master display device comprises a drive unit, a first control unit and an HDMI output interface. The drive unit generates a first drive signal. The first control unit generates a brightness adjustment signal under the condition of judging that the first drive signal satisfies a brightness adjustment condition for carrying out brightness adjustment on the expanded display device. The HDMI output interface inputs the brightness adjustment signal to the expanded display device. The expanded display device adjusts display brightness according to the brightness adjustment signal. According to the method and the system, the technical problem that in the prior art, the double-screen display system cannot adjust the display brightness of the expanded display device through the master display device is mitigated.
Description
Technical field [0001] The present invention relates to the technical field of dual-screen display, in particular to a dual-screen display method and system. Background technique [0002] In recent years, electronic devices that require display screens can be seen everywhere in all walks of life, such as ticket vending machines in movie theaters, cash registers in supermarkets, and advertising machines in the field of publicity. Moreover, with the development of science and technology, more and more electronic devices are usually equipped with extended display screens in addition to the main display screen, which can realize the function of dual-screen display, which greatly meets the needs of users and makes users While running system programs and some applications on the main display screen, you can also watch richer display images on the extended display screen of the electronic device. For example, the user can watch on the extended display screen while playing games on the m...
