LCD TFT Datasheet Rev.1.0 RiTFT-35 series 2.1 Mounting frame For dimensions 3.5”, 4.3”, 5.0” and 7.0” the product with mounting frame version is available. Thanks to the four catches attached to the side, frame provides strong assembly to the surface by mounting element (like the screw, see Figure 3). The frames are specially designed to fit Riverdi products perfectly. The diameter of the mounting hole is 3.5mm. Figure 1. Mounting frame © 2018 Riverdi Page 4 of 24 www.riverdi.

LCD TFT Datasheet Rev.1.0 RiTFT-35 series Note 1. Contrast Ratio(CR) is defined mathematically as below, for more information see Figure . Contrast Ratio = Average Surface Luminance with all white pixels (P1, P2, P3, P4, P5) Average Surface Luminance with all black pixels (P1, P2, P3, P4, P5) Note 2. Surface luminance is the LCD surface from the surface with all pixels displaying white. For more information, see Figure . Lv = Average Surface Luminance with all white pixels (P1, P2, P3, P4, P5) Note 3.
