Introduction to LK204-25-USB-WBThe LK204-25-USB-WB is a display module that is part of the LCD, OLED Character and Numeric category of display modules. It has an integrated USB controller and LCD display. The module is built with an STN-type LCD display and operates in full color graphics mode using 4,000 colors. It has a pixel resolution of 320x240 and a contrast ratio of 250:1.Application fieldThe LK204-25-USB-WB is a popular choice for point of sale retail terminals, instrumentation devices, medical equipment, and gaming consoles. Its USB connection ensures compatibility and reliability with many consumer electronic devices. Its small size allows it to be used in portable and handheld devices for displaying digital images or text.Working PrincipleThe LK204-25-USB-WB has a unique technology to drive the LCD display called Resonant-Switching. This technology enables the operation at a wide range of input voltages and eliminates the need for an external transformer. The internal oscillator works with a constant frequency and low distortions are achieved with the use of fast rise time MOSFET switches. The module is also capable of dimming the display brightness with pulse-width modulation (PWM). The adjustment of the brightness can be done through writing to the display memory at a specific address. This technology also leads to low power consumption and longer lifespans as the LCD display is not subjected to constant high voltage.ConclusionIn conclusion, the LK204-25-USB-WB module is a great choice for applications where the display device needs to be small and require USB connection. With its low power consumption and range of input voltages, this display module is perfect for consumer electronic devices. The Resonant-Switching technology and the PWM power dimming feature ensure that the device can be used for a variety of applications.
