Array substrate and display device comprising same

The invention belongs to the technical field of display, in particular to an array substrate and a display device comprising the same. The array substrate comprises a substrate as well as a plurality of data cables and a plurality of grid lines which are arranged on the substrate in a crossed manner, wherein the data cables and the grid lines divide the substrate into a plurality of pixel areas, and thin film transistors are arranged in the pixel areas; each thin film transistor comprises a grid electrode, a source electrode and a drain electrode; and the array substrate further comprises colored films and black matrixes, the colored films are directly arranged on grid electrodes located on the upper layers of the thin film transistors or above the source electrodes and the drain electrodes which are located on the upper layers of the thin film transistors, the arrangement directions of the colored films are identical with extending directions of the data cables, and the black matrixes are arranged above the grid lines corresponding to the colored films. The array substrate and the display device have benefits as follows: the aperture ratio is higher, the image picture contrast is high, the cost is lower, the preparation process is simpler, and requirements for high resolution, lightness and attractiveness are easy to meet.

Continuous zooming infrared lens with extra large zoom ratio

ActiveCN103852874AFacilitates target search with a large field of viewImprove light transmittanceOptical elementsPhysicsCamera lens
The invention relates to a continuous zooming infrared lens with an extra large zoom ratio. The continuous zooming infrared lens with the extra large zoom ratio is sequentially provided with a front fixing set, a zoom set, a compensation set, a first rear fixing set, a focusing set and a second rear fixing set along an optical axis from the object side, the zoom set and the compensation set are a biconcave negative lens and a biconvex positive lens respectively, the first rear fixing set is a negative meniscus lens, and the focusing set and the second rear fixing set are respectively a positive meniscus lens. The six lens have the positive diopter, the negative diopter, the positive diopter, the negative diopter, the positive diopter and the positive diopter respectively. When the lens changes from the wide angle state to the long focus state, the distance from the zoom set to the front fixing set and the distance from the compensation set to the first rear fixing set increase gradually. The infrared lens can achieve the ultra large zoom ratio of ten times or more. Because only the six lens are adopted, the light transmittance is guaranteed; the infrared lens is compact in structure and easy to install, adjust and assemble and has the temperature compensation function.

Under-screen camera assembly and corresponding terminal equipment

The invention provides an under-screen camera assembly, and the assembly comprises an organic light-emitting diode display screen whose display region comprises an under-screen camera shooting area and a non-under-screen camera shooting area; and a camera shooting module which is located at the rear end of the under-screen camera shooting area, and comprises a lens cone, a lens set and a photosensitive assembly. The lens cone comprises a lens set installation section and an extending section; the lens set is installed on the inner side face of the lens set installation section; and the extending section is formed by extending upwards from the top of the lens set installation section, and the top surface of the extending section leans against the bottom surface of the organic light emittingdiode display screen. The invention further provides corresponding terminal equipment. According to the application, the extending part is arranged at the top of the lens cone to enable the screen and the camera shooting module to lean against each other, so that the camera shooting module can be accurately aligned with the under-screen camera area; and the lens set with the same optical design can adapt to terminal equipment of multiple models with different sizes.
