A surface light source device and LCD employing light guide plates having inconspicuous micro-reflector arrays are provided. Alight guide plate 30 illuminating an LCD panel of a surface light source device has a back face 32 provided with many micro-reflectors 20 arranged with sidewise intervals on imaginary lines Ki which are generally perpendicular to an imaginary reference line S with longitudinal intervals getting smaller according to an increasing distance from an incidence face 33. On each imaginary line Ki, the sidewise intervals get smaller or micro-reflector sizes get larger according to an increasing distance from the reference line S. Making many microreflector trios each of which consists of micro-reflectors arranged adjacent to each other and on any imaginary lines Ki to Ki+2, each of the trios has micro-reflectors are located generally on a straight line. Covering rate of the micro-reflectors increases according to an increasing distance from an incidence face 33. The imaginary lines Ki may be curved gently.

A structure of a backlight module, which includes: a light source frame, including: a top plate having a plurality of slits; a bottom plate arranged apart from the top plate; and at least two edge plates arranged oppositely, wherein each of the edge plates has a top end and a bottom end, and both of the bottom ends are separately connected with the bottom plate; wherein the inner surfaces of the top plate, the bottom plate and the edge plates form a reflective cavity; and at least one light source arranged in the reflective cavity. There are several advantages of the backlight module according to the present invention, which includes: 1. the required uniformity and brightness of the backlight module are achieved; 2. its weight is largely reduced; and 3. it can be tiled up to form a large-area backlight module for a large size display.

Near infra-red images of natural scenes usually have better contrast and contain rich texture details that may not be perceived in visible light photographs. The contrast and rich texture details form a NIR image corresponding to a visible light image are useful for enhancing the visual quality of the visible light image. To enhance the visual quality of a visible light image using its corresponding near infra-red image, a computer-implemented method computes a weight region mask from the visible light image, transfers contrast data and texture data from the near infra-red image to the visible light image guided by the weighted region mask. The contrast data is computed from the low frequency subbands of the visible light image and corresponding infra-red image after a wavelet transform by matching the histogram of gradient magnitude. The texture data is computed from the high frequency subbands of both images after wavelet transform.

A display device has a light guide plate formed with a display pattern by a plurality of diffusion dots having translucency in a display pattern formed region, a light shielding layer, and a light source. A plurality of the light guide plates are arranged facing each other, and the light shielding layer is sandwiched between the light guide plates. Light from the light source is selectively introduced to one of the light guide plates to display the display pattern of the light guide plate. The light shielding layer has a surface facing an observer's side formed by a low reflectivity material and a surface facing a side opposite to the observer's side formed by a high reflectivity material. A region facing the display pattern of the light guide plate positioned on the side opposite to the observer's side than the light shielding layer is cut out.

The present disclosure relates to an organic light emitting display panel and a display apparatus. The organic light emitting display panel includes: a first substrate provided with a plurality of pixels each comprising an organic light emitting diode; a second substrate having at least one auxiliary electrode electrically connected to a cathode of the organic light emitting diode, each auxiliary electrodes being located on a side of the second substrate facing the first substrate and corresponding to a gap between adjacent pixels on the first substrate; and an antireflection layer formed on the auxiliary electrode for absorbing light rays directed to the auxiliary electrode. In the present disclosure, by the auxiliary electrode formed on the second substrate and electrically connected to the cathode on the first substrate, the voltage drop of the cathode may be significantly reduced, and the uniformity of the display brightness is improved. Meanwhile, by the antireflection layer formed on the auxiliary electrode, light leakage phenomenon due to reflection of a metal auxiliary electrode may be prevented, thereby improving contrast ratio of the display.

The present invention provides a light emitting diode (LED) element which comprises a substrate, a buffer layer, a plurality of nano-spheres and a light emitting structure. The substrate comprises a plurality of grooves arranged at intervals on a surface of the substrate. The buffer layer is disposed on the surface of the substrate where the grooves being formed, wherein the grooves are disposed between the substrate and the buffer layer. The nano-spheres are received in the grooves, so each groove is provided with at least a nano-sphere. The light emitting structure is disposed on the buffer layer.

A vehicle headlight comprising at least one lighting module mounted on a support. The module comprises a base with a mounting surface inclined backward and toward the top of the headlight. The support comprises a corresponding mounting surface. Positioning means with sliders are provided on these surfaces so as to be able to extract the module and fit it by a translational movement in a direction contained within the plane of the mounting surfaces. The housing comprises a removable portion positioned in the extension of the module in the direction of translation of the positioning means with sliders. The wall of the housing comprises precuts on the circumference of the removable portion. This arrangement makes is possible to easily replace a bulky lighting module such as that of a headlight with style functions.
