The imaging lens system is disposed between a preloading element and a driving base of the lens driving module. The preloading element includes an injection molded part and a ferromagnetic part partially embedded in the injection molded part. A rollable element is disposed in each of mounting structures of the injection molded part and in contact with a displaceable lens carrier of the imaging lens system.

The driving base includes a driving coil and an electrical wiring pattern. The driving coil corresponds to the magnet for generating a driving force to drive the displaceable lens carrier to move along the optical axis.

Abstract: A method for converting input RGB data signals to output RGBW data signals for use in an OLED display is disclosed. In the OLED display, each pixel has three color sub-pixels in RGB and one W sub-pixel. Input RGB data signals in signal space are normalized and converted into input data in luminance space. A baseline adjustment level is determined from the input data and is used to compute baseline adjusted data in luminance space. After being converted from luminance space into signal space, baseline adjusted data in RGBW are represented by N binary bits presented to the four sub-pixels. To suit the color characteristics of the display, color-temperature correction to the output signals is also carried out. In luminance space, the maximum color-temperature corrected output data fall within the range of 0.4/k and 0.5/k, with k being the ratio of W sub-pixel area to the color sub-pixel area.
