A backlight module for a display panel of a display device is provided. The backlight module comprises a light-emitting unit and a control unit. The light-emitting unit provides light to the display panel. When the display panel displays images in a first mode, the control unit drives the light-emitting unit to emit light of a first total brightness. When the display panel displays images in a second mode, the control unit drives the light-emitting unit to emit light of a second total brightness.

A display capable of providing 2D and/or 3D images. The display comprises a liquid crystal display device and a self-emissive display device. The self-emissive display device is disposed on the rear of the liquid crystal display device, in which the liquid crystal display device provides a first image and the self-emissive display device a second image and a backlight source. One of the first and second images comprises a parallax barrier pattern for forming a three-dimensional (3D) image, and the other is a 2D image.

An LCD panel includes an array substrate, a color filter substrate positioned above the array substrate, a dielectric layer disposed on the array substrate facing the color filter substrate, and a liquid crystal layer interposed between the array substrate and the color filter substrate. The color filter substrate includes a plurality of red pixel regions, green pixel regions, and blue pixel regions, and the dielectric layer has different thickness corresponding to the red pixel regions, the green pixel regions, and the blue pixel regions. Accordingly, the liquid crystal layer has a first thickness corresponding to the blue pixel regions, a second thickness corresponding to the green pixel regions, and a third thickness corresponding to the red pixel regions. The first thickness is less than the second thickness, and the second thickness is less than the third thickness.

A viewing-angle adjustable liquid crystal display includes a display panel, a backlight unit, and a sidelight unit. The backlight unit is located under the sidelight unit, and the sidelight unit is disposed under the display panel. The sidelight unit includes a first sidelight source and a light-guide plate. The first sidelight source is disposed at one end of the light-guide plate. The displaying method includes providing direct light to the display panel in response to the narrow-viewing-angle-mode signal; and providing scattering light to the display panel in response to the wide-viewing-angel-mode signal.

An improved ratchet wheel structure of a ratcheting wrench, having a restricting base at the bottom of the ratchet wheel, wherein the external diameter of the restricting base is slightly smaller than the diameter of the bottom hole on the fixing base of the ratchet wheel, and it extends to the intersection point of the ratchets of the ratchet wheel to form a serrated disk, and the ratchets aligned in parallel with the axial direction in the middle section of the ratchet wheel, and it extends to the intersection point of the positioning area such that the tip of the ratchets is corresponsive to the external diameter of the ratchet wheel, and a latching groove being disposed around an appropriate position in the positioning area such that a C-shaped buckle being latched into the latching groove for positioning. The ratchet wheel is embedded into the fixing groove of the ratchet wheel, and the serrated disk of the ratchet wheel and the restricting base just fit into the accommodating groove of the cross base and the restricting hole for the positioning, and the C-shape buckle will then be embedded into the inner edge of the hole in the accommodating groove such that the ratchet wheel in the accommodating groove will not fall off. Since the ratchets of the ratchet wheel are relatively of the same size as the external diameter of the ratchet wheel, the ratchets can keep its minimum external diameter for the ratchet wheel, and allow maximum effective ratchet diameter for the pawls of the blocking member for the engagement of the ratchets in order to strengthen the ratchets and avoid them from being cracked. In addition, the ratchet wheel and the ratchets are formed integrally to accomplish the effect of easy manufacture and quality inspection.

A method of fabricating a circuit board structure with concave conductive cylinders is provided. Firstly, a conductive layer is provided and a dielectric layer is formed on a surface of the conductive layer. Next, a plurality of vias is formed in the dielectric layer, where the vias are exposed on the surface of the conductive layer. A conductive material is then filled in the vias to form a plurality of conductive cylinders on the surface of the conductive layer, so that the tips of the conductive cylinders are exposed on a surface of the dielectric layer relatively far away from the conductive layer. The exposed tips of the conductive cylinders are removed, so that the height of the conductive cylinders is lower than the dielectric layer and the conductive cylinders sunk into the dielectric layer.

A mobile device protective case (10) includes a frame (20) and a slidable shutter (30) mounted on the frame (20) to function as a slidable component. After a mobile device (50) has been inserted into the frame (20), the slidable shutter (30) hides a touch panel (51) of the mobile device (50) to prevent the touch panel (51) from being scratched or scraped. To start using the mobile device (50), a user moves the slidable shutter (30), such that the touch panel (51) of the mobile device (50) is exposed and can be directly operated by the user.
