First, the screen protection control related signals: 1. VDD-DET power supply detection signal: The logic board's CN2033 socket 14 and 15 provide a 5V power supply to the X drive component's CN4001 socket 14 and 15. This voltage is directly connected to the X drive component’s power supply. Additionally, the CN4701 socket 13 pin sends this signal through a cable to the Y drive component’s CN5001 socket 13 pin, forming the VDD-DET power detection signal. 2. Y adapter component power supply detection signal: The Y drive components T5000 (LJ26-00105A) and U5001 (FSL136MR) generate the VSCAN voltage and provide two power supplies for the Y adapter component: 17V and 144V. The 17V power is delivered from the Y drive component’s CN5002 pin 4 to the Y adapter component’s CN5400 pin 9, while the 144V power comes from the Y drive component’s CN5002 pins 1 and 2 to the Y adapter component’s CN5400 pins 11 and 12. The 17V also goes directly to the CN5403 socket pin 11 and is transmitted via a connector to the Y drive component’s CN5005 socket pin 2. The 144V powers the Y adapter IC and is tested, with the result output to CN5403 socket pin 10 in open-drain mode, then sent to the Y drive component’s CN5005 socket pin 3 via a connection. 3. Protection request signal (DRV-RESET) and protection execution signal (DS-RESET): DRV-RESET is a signal sent by the Y drive component to the logic board when an error is detected. It is normally low, and a high level indicates a protection request. This signal is sent from the Y drive component’s CN5006 socket pin 21 to the logic board. DS-RESET is the signal sent from the logic board to the Y drive component to trigger protection. A high level activates the protection, and it is sent from the Y drive component’s CN5006 socket pin 22. Second, S50HW-YD14 screen protection circuit (on Y drive components): The S50HW-YD14 protection circuit receives VDD power from the logic board’s CN2022 socket through a cable, connecting to the Y drive component’s CN5006 pins 25 and 24 to power the protection detection circuit. The 17V power passes through resistors R5007 and ZD5000, lighting the optocoupler LED. The secondary side acts as a short, and the optocoupler’s 4th pin is grounded. U5005’s 3rd pin is low, and U5003’s 17th pin outputs low, which is sent to the double diode D5009’s 1st pin. At the same time, the VDD-DET signal from CN5001 is divided by R5013 and R5058, turning on Q5004 and pulling its collector low to D5009’s 3rd pin. These two low-level signals are combined through OR gates formed by D5009, R5014, and R5011, and are sent to the Y drive component’s CN5006 socket 21 pin (DRV-RESET). When the logic board detects a low DRV-RESET signal, it confirms the screen circuit is functioning properly. On the other hand, if the X board is disconnected or damaged, the VDD-DET signal cannot activate Q5004. The VDD power flows through R5012 and D5009 to ground, preventing the optocoupler from emitting light. The secondary side becomes an open circuit, and the VDD power is divided through R5008 and R5088, sending a high-level signal to U5005’s 3rd pin. After being amplified, a high-level DRV-RESET signal is generated through D5009, R5014, and R5011. Similarly, if the Y switch component detects an issue with the 144V power supply, Q5401 turns on, shorting the optocoupler’s 1st pin to ground, causing the optocoupler to stop emitting light and generating a high DRV-RESET signal. When the logic board detects a high DRV-RESET signal, it immediately triggers protection: it sends a DS-RESET signal through the Y drive component’s CN5006 socket pin 22, which is applied to U5005 and U5000 pin 1, grounding them. This turns off the two chips’ outputs, halting subsequent operations and cutting off signal input. The logic board also sends a VS-ON shutdown signal to the power board, turning off the VS and VA power supplies for protection. This screen protection mechanism is identical to that of the S50HW-YD13, making it suitable for maintenance purposes.
The Solar Battery is an innovative device that harnesses the power of the sun to store energy for later use.
