The GC9307, a TFT LCD driver with QVGA resolution, has gained widespread use among LCD module manufacturers since its launch. Sinocrystal are excited to share a series of practical insights we have gathered from using the GC9307 driver.
Basic Features of the GC9307
The GC9307 supports full-color, 8-color display modes, and a sleep mode, allowing for flexible display adjustments based on specific needs. Additionally, its precise power control via software helps reduce energy consumption and extend device battery life. It integrates several on-chip functions, including a timer generator, oscillator, DC/DC converter, and point/column inversion, significantly simplifying circuit design.
In terms of interfaces, the GC9307 provides an 8-/9-/16-/18-bit parallel system interface for the 8080-I/8080-II series, and supports 3-/4-line serial system interfaces, offering great convenience for connecting with different devices. The external IM [3:0] pins select the input system interface, and the pixel color sequence is determined by the 3-bit setting of the DBI [2:0] 3Ah register, ensuring accurate data transmission.
How to Use the GC9307
As the core driver for TFT LCD screens, using the GC9307 involves hardware connections, software configuration, and display control. First, connect the GC9307 to the TFT LCD screen using an appropriate interface (such as parallel 8080 or SPI) to ensure correct data and power signal transmission. Next, configure the GC9307 through software based on application needs, including setting display mode, color depth, and resolution. Finally, write control code to send commands and data to the GC9307, enabling image display and updates. In software control, the GC9307 supports various commands and data formats, allowing developers to configure it flexibly.
