3.6 Power On/Off Sequence
The specification details a precise power-on and power-off sequence that must be strictly followed to avoid damage to the module. Key timing parameters include delays between VCCS, HPD, AUX channel, valid video data, and LED converter control signals (VLED, LED_EN, LED_PWM).
Critical Requirement: The backlight must be turned on after the power supply for the logic and the interface signal is valid. The backlight must be turned off before the power supply for the logic and the interface signal is invalid. Failure to adhere to the sequence may cause abnormal display or permanent damage.
4. Application Scenario
The LS156I02-E-V1's 15.6-inch diagonal size with Full-HD (1920×1080) resolution and IPS technology for free viewing direction make it an excellent choice for a wide range of applications including notebook computers, portable monitors, and industrial displays where high image quality and wide viewing angles are critical.
5. Handling Precautions And Compliance
The LCD panel is made of glass and is fragile. The polarizer surface is easily scratched. The module should be handled with care to avoid applying pressure on the display area. ESD (Electrostatic Discharge) protection is mandatory throughout handling and assembly. The module should be stored in a clean, dry environment away from direct sunlight and corrosive gases. It is strongly recommended to read the full specification document (LS156I02-E-V1 Product Specification Revision 1.0) before integration and to test the module under application-specific conditions to verify compatibility and performance. The manufacturer disclaims liability for damages resulting from improper use or modification.
