The present disclosure relates to an automatic detection system for a display.

When developing new all-in-one (AIO) computers or external monitors, there is a chance that the AIO computer and external monitor will not display the screen, or the screen will appear after a long time.

As used herein, “coupling” or “signal connection” may refer to direct physical contact or indirect physical contact between two or more modules or devices, or mutual operation or action between two or more modules or devices.

The terms "include", "including", "have", etc. used in this document are open terms, meaning including but not limited to.

As shown in FIG. 1 , the display automatic detection system 100 includes a microcontroller 110 , a relay 120 , an all-in-one computer 130 , an external display 132 , a first brightness detector 140 , and a second brightness detector 142 .

The relay 120 is connected to the microcontroller 110 , wherein the relay 120 is powered on after receiving a power-on signal 200 transmitted from the microcontroller 110 , and is powered off after receiving a power-off signal transmitted from the microcontroller 110 .

The all-in-one computer 130 is electrically connected to the relay 120, and when the relay 120 is powered on, it can provide power to the all-in-one computer 130. In some embodiments, a program code is input into the all-in-one computer 130, so that the all-in-one computer 130 automatically turns on after the relay 120 is powered on, and the all-in-one computer 130 automatically turns off after the relay 120 is powered off. Since the screen 130M of the all-in-one computer 130 and the host are located in the same body, when the all-in-one computer 130 is powered on, the screen lights up together, and when the all-in-one computer 130 is powered off, the screen turns off together.

The external display 132 is connected to the all-in-one computer 130, and when the all-in-one computer is turned on, it can provide a picture signal to the external display 132. In the present disclosure, the external display 132 is configured in a standby state, so that when the all-in-one computer 130 is turned on, the external display 132 is lit together, and when the all-in-one computer 130 is turned off, the external display 132 is turned off together.

The first brightness detector 140 is connected to the microcontroller 110 and is hung in front of the screen of the all-in-one computer 130 to detect the brightness of the screen after the all-in-one computer 130 is turned on. The second brightness detector 142 is connected to the microcontroller 110 and is hung in front of the external display 132 to detect the brightness of the external display 132 after it is turned on.

In some embodiments, the all-in-one computer 130 can be connected to 1 to 10 external displays 132 at the same time. And a corresponding number of second brightness detectors 142 can be configured according to the number of external displays 132.

As shown in FIG. 2 , the microcontroller 110 transmits a power-on signal 200 to the relay 120, and the relay 120 is powered on after receiving the power-on signal 200. After the relay 120 is powered on, the all-in-one computer 130 automatically turns on, and the external display 132 lights up.

Before the actual detection, the reference startup brightness and startup duration are measured. The first brightness detector 140 detects the brightness of the all-in-one computer 130 and records the first reference brightness 210 and the first reference duration 220 of the screen of the all-in-one computer 130. At the same time, the second brightness detector 142 detects the brightness of the external display 132 and records the second reference brightness 212 and the second reference duration 222 of the external display 132.

The first reference brightness 210 and the second reference brightness 212 are respectively the maximum brightness of the screen of the all-in-one computer 130 and the external display 132 after lighting up. The first reference duration 220 and the second reference duration 222 are respectively the duration of time for the screen of the all-in-one computer 130 and the external display 132 to light up to the maximum brightness after the microcontroller 110 transmits the power-on signal 200 to the screen of the all-in-one computer 130 and the external display 132. As shown in FIG. 2, the first brightness detector 140 and the second brightness detector 142 transmit the first reference brightness 210, the first reference duration 220, the second reference brightness 212 and the second reference duration 222 to the microcontroller 110.

Next, referring to FIG. 3 and FIG. 4, when the microcontroller 110 receives the first reference brightness 210, the first reference duration 220, the second reference brightness 212, and the second reference duration 222, the microcontroller 110 generates a power-off signal 202 and transmits it to the relay 120. The relay 120 is powered off after receiving the power-off signal 202. After the relay 120 is powered off, the all-in-one computer 130 is automatically shut down, and the external display 132 is turned off.

After the microcontroller 110 generates the power-off signal 202, the microcontroller 110 sets the detection time 330 and the power-off time 332. The microcontroller 110 sets the detection time 330 according to the first reference time 220 and the second reference time 222, wherein the detection time 330 is greater than the first reference time 220 and the second reference time 222. For example, when the second reference time 222 is greater than the first reference time 220, the detection time 330 may be the second reference time 222 plus 5 to 20 seconds. In order to speed up the detection operation, setting an excessively long detection time 330 may cause a delay in the detection, and an appropriate detection time 330 may be set according to actual needs.

Next, the microcontroller 110 sets a power-off duration 332 greater than the above duration according to the time length from the generation of the power-off signal 202 to the external display 132 being turned off. For example, the power-off duration 332 can be the time length from the generation of the power-off signal 202 to the external display 132 being turned off plus 5 to 20 seconds. The appropriate power-off duration 332 can be set as required. In some embodiments, the second brightness detector 142 can transmit the turn-off signal 230 of the external display 132 to the microcontroller 110.

As shown in FIG. 4 , after the microcontroller 110 sets the detection time 330 and the power-off time 332, the microcontroller 110 generates a detection power-on signal 300 to the relay 120. After the detection time 330, the microcontroller 110 generates a detection power-off signal 302. After the power-off time 332, the microcontroller 110 generates the detection power-on signal 300 again.

Next, referring to FIGS. 5 to 6, the display automatic detection system 100 performs a cyclic detection. The microcontroller 110 generates a detection power-on signal 300, and the relay 120 is powered on after receiving the detection power-on signal 300. After the relay 120 is powered on, the all-in-one computer 130 automatically turns on, and the external display 132 lights up. At this time, the first brightness detector 140 detects the brightness of the all-in-one computer 130, and records the first detection brightness 310 and the first detection duration 320 of the screen of the all-in-one computer 130. At the same time, the second brightness detector 142 detects the brightness of the external display 132, and records the second detection brightness 312 and the second detection duration 322 of the external display 132. The first brightness detector 140 and the second brightness detector 142 transmit the first detection brightness 310, the first detection duration 320, the second detection brightness 312 and the second detection duration 322 to the microcontroller 110 respectively.

After the detection time 330, as shown in FIG. 6, the microcontroller 110 generates a detection power-off signal 302, and the relay 120 is powered off after receiving the detection power-off signal 302. After the relay 120 is powered off, the all-in-one computer 130 is automatically shut down, and the external display 132 is turned off.

After the power-off time 332 has passed, the microcontroller 110 generates the detection power-on signal 300 again. In some embodiments, 500 to 600 cycles of detection are performed. For example, the microcontroller 110 can be set to stop generating the detection power-on signal 300 after receiving the first detection brightness 310 500 times. For example, it can also be set that the microcontroller 110 stops generating the detection power-on signal 300 after receiving the second detection brightness 312 550 times. The number of cycle detections can be set according to actual needs. With the display automatic detection system 100 disclosed in the present disclosure, more cycle detections can be performed without excessive labor consumption.

The microcontroller 110 may include a data processing module 112. The data processing module 112 is configured to determine whether the detection result is a success or a failure. In detail, in each detection, when the first detection brightness 310 is less than the first reference brightness 210, it is determined to be a failure. When the first detection duration 320 is greater than the first reference duration 220, it is determined to be a failure. When the second detection brightness 312 is less than the second reference brightness 212, it is determined to be a failure. When the second detection duration 322 is greater than the second reference duration 222, it is determined to be a failure. In addition, the data processing module 112 of the microcontroller 110 can calculate the failure rate (failure times/total detection times x 100%) according to the above judgment results.

In some embodiments, after the loop detection is completed, the all-in-one computer and/or the external display can be replaced before the next detection. For example, in the next detection, the all-in-one computer is replaced, but the external display is not replaced. For example, the all-in-one computer is not replaced, and some of the external displays are replaced, or all of the external displays are replaced.

In summary, the automatic display detection system disclosed in this case can be used to repeatedly test the brightness of the screen and external display of the all-in-one computer during research and development. In addition, the automatic display detection system disclosed in this case can automatically measure the brightness and duration and automatically record them, thereby reducing manpower consumption and improving detection accuracy.

Anyone skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of the patent application attached hereto.
