Abstract: A backlight module and a display device. The backlight module comprises multiple monochromatic light-emitting units (300), a transparent package layer (400) covered on the monochromatic light-emitting unit (300), a brightening layer (600) covered right above the package layer (400), and a composite function structure (500) provided between the package layer (400) and the brightening layer (600) and covering the package layer (400). By using the monochromatic light-emitting units (300) as a light source, the backlight module converts the monochromatic light into a compound light by means of the composite function structure (500), and reflects and scatters the light before emitting so as to reduce the number of monochromatic light-emitting units (300) and reduce the cost of a material. In addition, in addition to the light conversion function, the composite function structure (500) can also be composite with other optical functions. In this way, the thickness of the backlight module can be reduced so as to achieve the ultra-thin design, simplify the manufacturing process, and reduce the manufacturing cost.

Abstract: Provided in the present invention are a timing test method and device, and a VR chip. When a timing test is performed on a VR chip in a server board card, a circuit in the VR chip in the server board card is improved so that an enable voltage obtained by the circuit for dividing an input voltage of the server board card is an enable voltage under a critical state wherein the enable voltage is the maximum and the enable voltage does not drop to an uncontrollable interval when the input voltage drops. Since the circuit in the VR chip in the server board card may cause the enable voltage to not drop to an uncontrollable interval when the input voltage drops, the problem in which the output voltage of the VR chip is not monotonic during the timing test of the VR chip is prevented. Moreover, the circuit in the VR chip in the server board card may ensure that the enable voltage is the maximum on the basis that the enable voltage does not drop to an uncontrollable interval when the input voltage drops. Therefore, the problem in which the VR chip operates abnormally because the voltage is too low may also be prevented.

IPC: F21V5/02
Filed: 2019-07-20
Abstract: A polarizing beam splitter (PBS) (2)-based headlamp unit, comprising a lens (1) and a beam splitter (2). From the viewpoint of a reverse light path, parallel light is refracted twice by passing through the incident surface and exit surface of the lens (1), passes through the beam splitter (2) and then converges on at least two focal points (A, B, C). Each focal point corresponds to one light path system, and each light path system may turn on simultaneously or turn on alone so as to obtain a corresponding headlamp light pattern. The beam combining of the PBS (2) may enable two optical systems to achieve different illuminating light patterns by means of combinations of turning on and turning off light sources, and the two optical systems do not interfere with each other. The PBS (2) obtains at least two precise focal point positions for the focal points of the lens (1), and may accurately obtain an ideal light pattern. A high-beam light pattern may partially cover a low-beam light pattern, which may prevent the occurrence of a significant brightness mutation at the border of the light patterns.
