Problems solved by technology

However, in addition to the light source and photoelectric sensor, in order to obtain the image of the texture, it is also necessary to use a lens and other components to form an optical path system to control the optical path. The optical path system will make the device thicker and cost higher.

Embodiment Construction

[0041] Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed descriptions will be omitted. Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale.

[0042] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship of one component of an icon to another component, these terms are used in this specification only for convenience, for example, according to the description in the accompanyin...

Abstract

The disclosure provides an electronic device and a texture recognition device, and relates to the technical field of image recognition. The texture recognition device of the present disclosure includes a sensing layer, a transparent contact layer, a light-shielding layer and multiple light sources. The sensing layer includes a plurality of photosensitive units distributed in an array; the transparent contact layer is arranged on one side of the sensing layer; the light-shielding layer is arranged between the sensing layer and the transparent contact layer, and the light-shielding layer includes a plurality of light-transmitting parts arranged in an array; Light source Each light source array is distributed on the side of the light-shielding layer close to the transparent contact layer. The light emitted by the light source is reflected by the transparent contact layer and transmitted to the photosensitive unit through the light-transmitting part. The texture recognition device of the present disclosure can reduce thickness and cost.

Description

technical field [0001] The present disclosure relates to the technical field of image recognition, and in particular, to an electronic device and a texture recognition device. Background technique [0002] The recognition technology of fingerprints, palmprints and other lines has been widely used in various devices such as mobile phones and computers for identification and to improve the security of devices. Among them, the implementation methods of texture recognition mainly include optical, capacitive, and ultrasonic imaging technologies, among which optical texture recognition technology is more commonly used. [0003] At present, the optical texture recognition technology generally uses a light source to irradiate fingerprints, palmprints and other textures, and images the light reflected from the textures, and the texture information can be obtained through image processing. However, in addition to the light source and photoelectric sensor, in order to obtain the image...
