QE for Display: Development Assistance Tool for Display Applications


This development assistance tool supports the development of embedded systems which use the LCD display functions of display controllers from Renesas. It supports MCUs of the RZ and RX families.


New release: QE for Display[RX] V2.0.0
V2.0.0 of QE for Display[RX] now supports embedding of the emWin from SEGGER Microcontroller. You can use the GUI of QE for Display[RX] to adjust the display timing and quality of images as well as make settings required for the Segger emWin. These settings are automatically reflected in your project so you do not need to manually merge the source code generated by QE for Display[RX] with that generated from the Segger emWin.

QE for Display is one of several solution toolkits which operate within the e² studio integrated development environment.

This product can shorten times to develop embedded systems that include image display through the Video Display Controller 5 (VDC5) in the case of the RZ family and the graphics LCD controller (GLCDC) in the case of the RX family, since QE for Display eases the initial adjustment of the display.

Interlinkage with the separately available RZ/A Software Development Kit (for the RZ family) and Envision Kit (for the RX family) strongly supports the development of HMI applications.


Dedicated View for Easy Settings of LCD Panel Timing

Timing settings which match the refresh rate specification of the display are easy to obtain while checking the results on the actual display. Settings that are not in accord with the requirements of the LCD spec. are marked as being in error, so the user is easily able to identify problems.

(refer to the Note1)

Easy Slider-Based Adjustment of Image Quality Settings

This tool supports various functions for adjusting image quality. You can easily adjust the images while checking the actual display. QE for Display[RZ] supports the adjustment of brightness, contrast, sharpness, gamma correction, and dithering, as well as the rotation and mirroring of images. QE for Display[RX] supports processing to make the settings in a sequence of processing through settings for calibration, brightness, contrast, gamma correction, and then dithering.

(refer to the Note1)

The dedicated GUI makes setting complex gamma correction easy.

Checking the handy block diagram helps you to move around the settings screen without becoming confused.

(refer to the Note1)

Check the Settings on the Actual Display

A single button press writes the current settings to registers, so you can check the results on the actual LCD panel. This tool also has a mode for automatically writing the changes to registers every time a setting is changed.

Generate a Header File Which Reflects the Settings for Use in Projects

When you have finished the settings, the settings corresponding to those in the GUI display are created in a header file for direct incorporation in projects. QE for Display can also operate in conjunction with the Supported Sample Programs.
