Please select the most similar patent number from A, B, C and D. Which number is?
A housing assembly (110), comprising a transparent substrate (110) and a reflective layer (120); the transparent substrate (110) is provided with a decorative surface (111), and the decorative surface (111) is provided with coarse region (113); the reflective layer (120) is disposed on the decorative surface (111), and the reflective layer (120) covers at least a part of the coarse region (113).
A: A housing assembly (10), a processing method therefor, and an electronic device (100). The housing assembly (10) comprises: a substrate (1), which is provided with an inner surface and an outer surface which are arranged opposite to each other, the substrate (1) being a transparent piece; a touch layer (2), which is provided at the inner surface of the substrate (1), the touch layer (2) being suitable for electrically connecting to a motherboard (20) of the electronic device (100); and a decorative layer (10a), which is provided at a side surface of the touch layer (2) away from the substrate (1).
B: A screen (10) having a high contrast and high luminous efficiency comprises the following layers sequentially stacked from an incident side of projected light rays (31): a micro-lens layer (123), a transparent matrix layer (120), a total reflection layer (121), and a light-absorbing layer (11). The light-absorbing layer (11) absorbs light passing through the micro-lens layer (123), the transparent matrix layer (120) and the total reflection layer (121). The micro-lens layer (123) comprises a plurality of micro-lens units. The total reflection layer (121) comprises a plurality of microstructure units. The microstructure unit has a lower first flat surface (124) and an upper second flat surface (125). The first flat surface (124) intersects the second flat surface (125). The plurality of microstructure units form a serrated structure. The micro-lens units and the microstructure units are at least partially arranged in an alternating manner, such that the micro-lens units converge at least a portion of the projected light rays (31) toward the first flat surface (124). The projected light rays converged toward the first flat surface (124) exit after being totally reflected by the first flat surface (124) and the second flat surface (125) sequentially. Also disclosed is a projection system having the screen.
C: Disclosed are a color conversion assembly (100) and a manufacturing method therefor, and a display panel, wherein same can mitigate the problem of cross-coloring between neighboring sub-pixels and can improve the light extraction efficiency thereof. The color conversion assembly (100) comprises: a substrate (110); a light blocking layer (120) located on the substrate (110) and having a plurality of channels; and a color conversion layer (140) located in at least some of the channels, wherein the color conversion layer (140) converts incident light (L1) into light of a target color. The light blocking layer (120) comprises: a support layer (121) located on the substrate (110); a black matrix layer (122) extending continuously on an upper surface and a side surface of the support layer (121), wherein the upper surface of the support layer (121) faces away from the substrate (110); and a reflective layer (123) extending continuously on an upper surface and a side surface of the black matrix layer (122), wherein the upper surface of the black matrix layer (122) faces away from the substrate (110).
D: A liquid crystal display device and a reflective display module (11) thereof. The reflective display module (11) comprises: a first substrate (111); a reflecting layer (113) provided on the first substrate (111) and used for reflecting incident light; and a plurality of color resistors (112) provided on the reflecting layer (113), wherein the incident light enters the reflecting layer (113) through the color resistors (112), and is reflected by the reflecting layer (113) to obtain reflected light, and the reflected light is emitted through the same resistors (112). Therefore, the incident light and the reflected light are prevented from passing through two different types of color resistors (112), thereby improving the reflectivity and eliminating color mixture.
