The OLED display cable connector touch panel 2 is equipped with a touch circuit and a second IO port 202 for connecting the OLED display cable. The OLED display cable connector touch panel 2 is equipped with a touch area.

[0064] The touch circuit here is actually a touch signal controlled switch circuit, which is connected to the detection circuit board via the first FPC line 3 to perform the function of a switch.

[0065] The detection circuit board described in this embodiment includes a power board and a peripheral motherboard for detecting OLED displays.

[0066] The power board is equipped with a power supply switch circuit; the power supply switch circuit is connected to the peripheral motherboard via two power lines; the OLED display cable connector touchpad 2 is connected to the power board via the first FPC cable 3.

[0068] The working principle of the fixture is as follows: When the finger does not touch the touch area, the touch circuit does not detect a touch signal, the touch IC output pin outputs a high level, turns on the switch circuit, and the power board supplies power to the peripheral motherboard, so the OLED lights up; when the finger touches the touch area, the touch circuit detects a touch signal, the touch IC output pin outputs a low level, turns off the switch circuit, disconnects the peripheral main power supply, and the OLED turns off.

[0069] In this embodiment, the OLED display cable connector touchpad 2 is equipped with a touchpad working indicator light 201.

[0070] The touchpad indicator light 201 is connected to the power board via the first FPC cable.

[0071] Specifically, the touchpad assembly includes two touch areas; both touch areas are connected to the internal circuitry of the touchpad.

[0072] In practical applications, when the switch circuit is turned on, the power board supplies power to the peripheral motherboard, the OLED lights up, and the touchpad indicator light stays on; when the switch circuit is turned off, the peripheral main power supply is disconnected, the OLED turns off, and the touchpad indicator light turns off.

[0073] Specifically, both the peripheral motherboard and the power board are equipped with a first connector; the two ends of the second FPC line are respectively connected to the first connectors on the peripheral motherboard and the power board. The connector pins here include a lighting function.

Conversely, when the output is low, the OLED is turned off.

[0089] 4. The function of the touch circuit is to acquire touch signals. When the touch circuit does not detect a touch signal, it outputs a high level, and vice versa.

[0090] Example 2

[0091] As shown in Figures 1-7: This embodiment describes in detail the actual application process of an OLED display touch detection fixture. The fixture includes a fixture body 1 and an OLED display cable connector touch panel 2, which can realize efficient detection of OLED displays.

[0092] I. Fixture Preparation

[0093] The fixture body 1 has an integrated detection circuit board, which consists of a power board and a peripheral motherboard. The power board has a power switch circuit, which is connected to the peripheral motherboard via two power lines. Both the peripheral motherboard and the power board have an 18-pin connector (first connector), which is connected via a second FPC line to provide OLED lighting function. At the same time, there is also a power connection line between the two, so that the power board can control the power supply or power supply of the peripheral motherboard according to the touch signal.

[0094] The fixture body 1 has a built-in lithium battery connected to the power board. The fixture body 1 is equipped with a main power switch 102, which can control the power on and off of the entire fixture. It is also equipped with a Type-C charging port for charging the lithium battery inside the fixture. In addition, the fixture body 1 is equipped with a power indicator light 101 and a charging indicator light, both of which are connected to the power board and can display the working status of the fixture in real time.

[0095] The OLED display cable connector touchpad 2 includes a housing and a main control board. The housing has a second IO port 202 for connecting the OLED display cable; the main control board has a touch signal control switch circuit; two touch areas are embedded on the back of the housing, and a touchpad working indicator light 201 is provided on the front, both of which are connected to the main control board; both the main control board and the power board have 22-pin connectors (second connectors), which are connected through the first FPC line 3 for transmitting the lighting function and touch signals.

[0096] II. Testing Implementation Process

[0097] Turn on the main power switch 102 on the fixture body 1. The fixture will start up, and the power indicator light will show the current battery status. If the battery is low, it can be charged through the Type-C charging port.

[0098] After turning on the main power switch 102, since the finger is not touching the touch area, the touch circuit does not detect the touch signal. The touch IC output pin outputs a high level, the power supply switch circuit is turned on, the power board supplies power to the peripheral motherboard, the OLED display lights up, the touch panel working indicator light 201 stays on, and the power indicator light 101 also lights up, indicating that the fixture has entered the normal testing state.

[0099] To plug or unplug the OLED display cable, pinch the top and bottom of the OLED display cable connector touchpad 2 with your fingers, thus touching the two touch areas on the back of the OLED display cable connector touchpad 2. After the touch circuit detects the touch signal, the touch IC output pin outputs a low level, the power switch circuit is turned off, the power board disconnects the power supply to the peripheral motherboard, the OLED display turns off, and the touchpad indicator light 201 also turns off. At this time, it is safe to plug or unplug the cable.

[0100] After the ribbon cable is plugged in and unplugged, the finger leaves the touch area, the touch circuit does not detect the touch signal again, the touch IC output pin returns to a high level, the power switch circuit is turned on again, the power board resumes power supply to the peripheral motherboard, the OLED display lights up again, and the touchpad working indicator 201 and the power indicator 101 also light up again, and the testing of the OLED display continues.

[0101] Through the above implementation process, the OLED display touch detection fixture can efficiently complete the detection of OLED displays while ensuring safety, greatly improving the detection efficiency. At the same time, the indicator lights provide real-time feedback on the working status, making it easy for operators to keep track of the fixture's operation.

[0102] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can conceive of other specific embodiments of this utility model without creative effort, and these embodiments will all fall within the scope of protection of this utility model.
