Solutions for LCD Displays

LCD Displays have been replacing standard 7-segment displays in embedded systems at tremendous pace. It offers endless possibilities to the interaction between human and the devices. Be it displaying simple things such as text, numbers and graphs; it is also now possible to display videos and images on the same display panel.

Even though the LCD display enables more flexibility in the design, it sometimes takes the developer a longer time to come out with the final solution due to more complex processing and control required.

With Renesas display solutions, it is now possible to unleash your creativity in designing the best human-machine interface and implement it in a short time.

The following demonstration videos show how a high display performance and advanced functionalities can be achieved with our solution.


Strong Backup for Developers

Easy GUI design
GUI Development Environment

The display on a LCD panel usually consists of a collection of parts, such as buttons. Developers need to create not only a single static display, but also transitions on events such as when an icon is touched. Tools that enable developers to develop using a GUI provide strong support for developing such often complex processes.

Image Color Reduction

When the number of colors in an original image provided by a designer is reduced, image quality often degrades. This tool for the RZ/A1 can reduce image data size while minimizing the effect on image quality. Benefits to the system include more efficient use of resources and improved performance.

Create your own environment quickly
HMI Software Development Kit for RZ/A1

Displaying content on an LCD panel is only one requirement of a system. The board support package (BSP) for RZ/A1 provides the other functions that are required—such as camera, storage, and network—in a single package.

QE for Video Display Controller 5

QE for Video Display Controller 5 is a tool for the RZ/A1 that enables the settings of a connected LCD panel to be adjusted using a graphical interface. Even non-technical users can easily adjust the display using this tool. This tool runs as a plug-in in the e2 studio development environment provided by Renesas.
