Embodiment Construction

[0073] Certain terms are used in this specification and the following claims to refer to specific components, but those with ordinary knowledge in the art should understand that hardware manufacturers may use different terms to refer to the same component. Subsequent claims do not use the difference in name as the method of distinguishing components, but the difference in function of the components as the criterion for distinguishing. The "comprising" mentioned in the entire specification and subsequent claims It is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" includes any direct and indirect electrical connection means. Therefore, if the article describes a first device Coupling to a second device means that the first device can be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means.

Abstract

The present invention provides a light source device for a reflective microdisplay panel is disclosed. The light source device comprises: a first light bar, disposed on a first side of the reflective microdisplay panel. The first light bar comprises: a substrate, a plurality of micro LED units, and a controlling unit. The micro LED units are formed on the substrate, each micro LED unit corresponding to a screen area of the reflective microdisplay panel. The controlling unit is coupled to the micro LED units, and utilized for controlling luminance of each of the micro LED units individually according to luminance of the screen areas of the reflective microdisplay panel.

Description

technical field [0001] The present invention relates to an image sensor and a light source device, in particular to a pixelated light source device for a reflective micro display panel. Background technique [0002] Generally speaking, a liquid crystal silicon silicon reflective liquid crystal panel (LCoSpanel) has various sizes, such as 0.22 inch (inch), 0.29 inch, 0.45 inch, 0.5 inch or 0.7 inch, but the size of the traditional light emitting diode package cannot be based on A variety of different sizes of monocrystalline silicon reflective LCD panels to adjust. [0003] Please refer to figure 1 , figure 1 It is a simplified schematic diagram of a conventional LED package 100 for a single crystal silicon reflective liquid crystal panel 110, wherein the size of the single crystal silicon reflective liquid crystal panel 110 is 0.22 inches. The active area 112 of the monocrystalline silicon reflective liquid crystal panel 110 can be matched with a conventional LED package ...
