Detailed Description
The invention is further described below with reference to the figures and examples.
Referring to fig. 1, in an embodiment of the present invention, a display system 100 is provided, which includes a plurality of display devices 10 cascaded together, and for convenience of description, the display devices 10 are respectively referred to as a display device 10a, a display device 10b, display devices 10c, … …, and a display device 10 n. In this embodiment, the display device 10 is an LED display module.
Referring to fig. 2, each display device 10, the data processing module 15, the frame structure identifying module 17, the first bidirectional port a and the second bidirectional port B on the upstream side, the third bidirectional port C and the fourth bidirectional port D on the downstream side. In the present specification and claims, the upstream side of the display device 10 refers to a side communicatively connected to a previous display device, and the downstream side of the display device 10 refers to a side communicatively connected to a subsequent display device. Understandably, the upstream side and the downstream side are defined successively based on signal cascade, and are not defined according to the physical orientation. In the present embodiment, the display device 10 has two bidirectional ports (the first bidirectional port a and the second bidirectional port B) on the upstream side and two bidirectional ports (the third bidirectional port C and the fourth bidirectional port D) on the downstream side, but the present invention is not limited to this specific form, that is, the display device 10 may have more bidirectional ports on the upstream side and more bidirectional ports on the downstream side.
The first bidirectional port a and the second bidirectional port B on the upstream side, and the third bidirectional port C and the fourth bidirectional port D on the downstream side are all communicably connected to the frame structure identification module 17. The data processing module 15 is communicatively connected to the frame structure recognition module 17, and is configured to process and output the signal generated by the frame structure recognition module 17. The present invention does not relate to the improvement of the data processing module 15, and therefore, the data processing module 15 will not be described in detail.
Referring to fig. 1 and fig. 2, in the display system 100, except for the first and last two display devices 10a and 10n in the cascaded display devices 10, the first bidirectional port a and the second bidirectional port B on the upstream side of the other display devices are respectively connected to the third bidirectional port C and the fourth bidirectional port D on the downstream side of the previous display device. For example, the first bidirectional port a on the upstream side of the display device 10B is connected to the third bidirectional port C on the downstream side of the display device 10a, and the second bidirectional port B on the upstream side of the display device 10B is connected to the fourth bidirectional port D on the downstream side of the display device 10 a.
The first bidirectional port a and the second bidirectional port B on the upstream side of the display device 10a on the head are connected to the output terminal of the first controller 21, and the third bidirectional port C and the fourth bidirectional port D on the downstream side of the display device 10n on the tail are connected to the output terminal of the second controller 22. It is understood that the display system 100 further includes a ground line and a power line, and the plurality of display devices 10 a-10 n are connected to the ground line and the power line in parallel to receive power.
The frame structure recognition module 17 of each display device 10 is configured to recognize whether the signal input of each bidirectional port is abnormal, and perform corresponding processing when the abnormality is recognized. For example, when it is recognized that the signal input to the first bidirectional port a on the upstream side is abnormal, the second bidirectional port B on the upstream side is switched to the signal input port, thereby improving the reliability of the entire display system 100.
Even when the signal input to all the bidirectional ports on the upstream side of a certain display device 10, for example, the first bidirectional port a and the second bidirectional port B, is abnormal, the display device 10 and the display control method thereof according to the present invention can improve the reliability of the entire display system 100. In the following, referring to fig. 2 and fig. 3, an example is given in which the display device 10 has a first bidirectional port a and a second bidirectional port B on the upstream side and a third bidirectional port C and a fourth bidirectional port D on the downstream side.
Referring to fig. 2 and fig. 3, in the present embodiment, the display control method includes the following steps performed on the display device:
step S11: a first bidirectional port a on the upstream side of the display device 10 is taken as an input port; next, the flow advances to step S13;
step S13: recognizing whether the signal input of the first bidirectional port a is abnormal, if no abnormality is recognized, the flow proceeds to step S61: the display apparatus 10 enters a first operation mode in which the third bidirectional port C and the fourth bidirectional port D on the downstream side of the display apparatus 10 are output ports and output to the outside at the same time.
Accordingly, if it is recognized in step S13 that the signal input to the first bidirectional port a is abnormal, the flow advances to step S21: a second bidirectional port B on the upstream side of the display device 10 is taken as an input port; the flow then advances to step S23;
step S23: it is recognized whether the signal input to the second bidirectional port B is abnormal, and if no abnormality is recognized, the flow proceeds to step S61.
Therefore, when the present invention is implemented, as long as one of the bidirectional ports at the upstream side of the display device 10, for example, the first bidirectional port a or the second bidirectional port B, operates normally, the display device 10 can operate in the first operation mode, so that the entire display system 100 can operate normally, and the reliability of the display system 100 is improved.
As shown in fig. 4, although an abnormality occurs in the second bidirectional port B on the upstream side of the display device 10B, the first bidirectional port a on the upstream side of the display device 10c, and the first bidirectional port a on the upstream side of the display device 10d, this case does not affect the normal operation of the entire display system 100.
Referring again to fig. 2 and 3, further, if it is recognized in step S23 that the signal input to the second bidirectional port B is abnormal, that is, the signal inputs to the bidirectional ports on the upstream side of the display device 10 are both abnormal, the flow proceeds to step S31: a third bidirectional port C on the downstream side of the display device 10 is taken as an input port; the flow then advances to step S33;
step S33: recognizing whether the signal input of the third bidirectional port C is abnormal, if no abnormality is recognized, the flow proceeds to step S62: the display device 10 enters a second operation mode in which the third bidirectional port C on the downstream side of the display device 10 is used as an input port and the fourth bidirectional port D is used as a backup input port.
As shown in fig. 5, the first bidirectional port a and the second bidirectional port B on the upstream side of the display device 10c are both abnormal, that is, when abnormality occurs in the upstream side bidirectional ports of the display device 10c, the display devices 10a to 10b before the display device 10c receive the signal of the first controller 21, so as to operate normally, for example, in the first operation mode, the display device 10c and the display devices 10 d-10 n therebehind receive the signal of the second controller 22, so as to work normally, specifically, each of the display devices 10D-10 n has one of the downstream-side bidirectional ports, for example, the third bidirectional port C or the fourth bidirectional port D, as an input port, and the other downstream-side bidirectional ports as spare input ports, meanwhile, the first bidirectional port A and the second bidirectional port B on the upstream side are used as output ports and output to the outside at the same time.
Therefore, according to the present invention, when the two-way ports on the upstream side of a certain display device 10c are abnormal, the entire display system 100 can still operate normally, and the reliability of the display system 100 is improved.
Referring to fig. 2 and 3 again, further, if the signal input of the third bidirectional port C is identified as abnormal in step S33, the flow advances to step S41: taking the fourth bidirectional port D of the display device as an input port, the flow proceeds to step S43;
step S43: recognizing whether the signal input of the fourth bidirectional port D is abnormal, if no abnormality is recognized, the flow proceeds to step S63: the display device 10 enters a third operating mode in which the fourth bidirectional port D is used as an input port.
As shown in fig. 6, when the first bidirectional port a, the second bidirectional port B, and the third bidirectional port C of the display device 10C are all abnormal, the display devices 10a to 10B before the display device 10C receive the signal of the first controller 21, so as to operate normally, for example, in the first operation mode; the display device 10c and the display devices 10d to 10n therebehind can normally operate by receiving the signal of the second controller 22, so that the whole display system 100 can still normally operate as long as one bidirectional port on the downstream side is not abnormal under the condition that all the bidirectional ports on the upstream side and most of the bidirectional ports on the downstream side of a certain display device 10c are abnormal, and the reliability of the display system 100 is improved.
Referring to fig. 2 and 3 again, if the signal input of the fourth bidirectional port D is abnormal in step S43, at this time, all the bidirectional ports on the upstream side and all the bidirectional ports on the downstream side of the display device are abnormal, the process proceeds to step S64: the display device 10 enters the fourth operating mode, stops outputting to the outside, and turns off the PWM display.
As shown in fig. 7, all the bidirectional ports (e.g., the first bidirectional port a and the second bidirectional port B) on the upstream side and all the bidirectional ports (e.g., the third bidirectional port C and the fourth bidirectional port D) on the downstream side of the display device 10C are abnormal. At this time, the display devices 10a to 10b before the display device 10c receive the signal of the first controller 21 and can normally operate, and the display devices 10d to 10n after the display device 10c receive the signal of the second controller 22 and can normally operate. The display device 10c does not affect the normal operation of the other display devices 10a to 10b and 10d to 10n although the whole display device is failed; further, after the display device 10c turns off the PWM display, it is difficult for the user to detect the malfunction, so that the influence on the entire display system 100 is reduced, and the reliability of the display system 100 is improved.
There are various methods for identifying whether a signal input to a certain bidirectional port of the display device is abnormal. In this embodiment, as described in fig. 1 and fig. 2, the frame structure identification module 17 is used to identify whether the signal input of a certain bidirectional port is abnormal.
In this embodiment, the frame structure recognition module 17 determines the received data, and determines the error of the frame structure according to different signal timing designs, so as to control the corresponding port to receive the data and control the corresponding port to output the data. The erroneous frame structure data includes data that is maintained at a fixed level for a certain time DT or that the recognition module considers that the input frame structure does not comply with the timing rules required for the design. The time DT may be preset according to different applications.
The specific frame structure is also designed according to design requirements, and is not limited to one. For example, assuming that the transmitted data is RZ code, the frame header can be set to a specific value of 8 bits or 16 bits of data to indicate the correct frame structure, such as 8 'hAA, 16' h5555, etc. If the received data does not contain the specific data of the set frame header, the frame structure is judged to be wrong, otherwise, the frame structure is judged to be correct. Of course, the specific data set may be placed at the end of the frame. This is for example and not limited to.
The above examples merely represent preferred embodiments of the present invention, which are described in more detail and detail, but are not to be construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications, such as combinations of different features in various embodiments, may be made without departing from the spirit of the invention, and these are within the scope of the invention.
