Abstract We have developed a four primary front projector prototype in a multi HTPS panels configuration. The projector is based on modifications of the optical platform of an off‐the‐shelf high quality brand product. Standard 720p input signal is converted to the required multiprimary input using the ColorPeak™ algorithm implemented in the KESHET™ chip. The result is a substantial increase in color gamut and brightness.
