G104X1-L04 Technical Features
Next, we will focus on analyzing the technical features of the G104X1-L04 display panel to help readers gain a deeper understanding of its performance advantages.
l XGA Resolution (1024 × 768 pixels): The standard XGA resolution offers a balanced combination of clarity and compatibility, making it widely applicable across industrial systems, embedded devices, and legacy equipment.
l Ultra-High Contrast Ratio (1000:1): The high contrast ratio delivers deeper blacks and brighter whites, enhancing overall image clarity and detail.
l DE (Data Enable) Only Mode: Supporting DE-only mode simplifies the timing control design, reducing system complexity and improving integration efficiency for engineers.
l 180-Degree Rotation Display Option: The module supports a 180-degree rotation feature, providing greater flexibility for installation in various system designs and mounting orientations.
l Replaceable LED Light Bar: The backlight system features a replaceable LED light bar, which simplifies maintenance and extends the overall lifespan of the display module.
G104X1-L04 Limitations
In this section, we will briefly analyze the limitations of the G104X1-L04, including constraints across various aspects.
l Relatively Limited Resolution: It may be insufficient in scenarios with current high-resolution display requirements (such as Full HD and above).
l Relatively High Power Consumption: Due to the use of a high-brightness backlight design, it may impose certain power consumption pressure in devices that operate for long periods.
l Limited Interface Compatibility: It only supports the LVDS interface. For systems using mainstream newer interfaces (such as eDP), additional conversion circuits may be required, increasing design complexity.
G104X1-L04 Block Diagram
The Input Connector on the left side of the block diagram is the starting point where the display receives commands. Through the LVDS interface (RX0–RX3 and clock signals), the raw data sent from the computer motherboard is transmitted to the central Timing Controller (TCON). Acting like a traffic controller, the TCON precisely manages the data flow, decomposing the video signals and distributing them to the side Scan Driver ICs and the bottom Data Driver ICs.
Stable power support is essential for the operation of the display. The DC/DC Converter in the center of the diagram converts the external power input into various reference voltages required for circuit operation. Meanwhile, at the bottom, the LED Backlight Unit and its dedicated converter operate independently from the image signal processing. This subsystem receives power (Vi) through a 10-pin connector and provides a uniform background light source for the screen.
G104X1-L04 Interface & Pinout
The G104X1-L04 display uses an industry-standard LVDS (Low Voltage Differential Signaling) interface, which not only ensures superior data transmission stability but also features exceptional EMI (Electromagnetic Interference) resistance.
