Abstract:
The disclosure is related to a light guide plate having a light-emitting surface, wherein a plurality of V-shaped grooves is formed on the light-emitting surface; each of the V-shaped grooves extends along a curved path. The V-shaped grooves of the light guide plate extend along the curved path to avoid the light guide plate from collecting light in a single direction. The interference fringes of the light guide plate are reduced, thereby improving the uniformity of light emission of the light guide plate.
Abstract:
Disclosed is a dial plate of an intelligent wristwatch, which includes a body, a first screen, a second screen, and a third screen. The first screen is rotatably connected to the body by a first rotary axle. The second screen is rotatably connected to the body by a second rotary axle. The third screen is rotatably connected to the body by a third rotary axle. The second rotary axle and the third rotary axle are opposite to and parallel to each other. The first rotary axle is perpendicular to the second rotary axle. Vertical distances of the first rotary axle, the second rotary axle, and the third rotary axle from the body are reduced in sequence so that the first screen, the second screen, and the third screen are allowed to overlap each other on the body. Also disclosed is an intelligent wristwatch having an expandable display screen.
Abstract:
The invention provides a splicing backplane for a backlight module, which is arranged on the backside of the backlight module. The splicing backplane comprises a mounting portion and a supporting portion, wherein the horizontal height of the mounting portion is level with or lower than that of the supporting portion; and a plurality of the splicing backplanes are assembled together by the mutual superposition of various mounting portions. A plurality of the splicing backplanes are superposed with each other and combined into one, and the height differences between the mounting portions and the supporting portions of two adjacent backplanes are unequal, so that one backplane can be accommodated into the other backplane. In addition, after the superposition, the overall thickness of the backplanes is invariable.
