Problems solved by technology

However, when the light emitted by the light emitter into the first optical window is strung into the second optical window and then received by the light sensor (that is, the light signal emitted by the light emitter is directly received by the light sensor without being absorbed and reflected by the skin), It will lead to the deviation of the calculation results, which will reduce the accuracy of the detection results.

Abstract

The embodiment of the invention provides a preparation method of a cover plate, the cover plate and an electronic device. The preparation method of the cover plate comprises the following steps: providing a first light-transmitting material, a second light-transmitting material and a shading material; the first light-transmitting material and the second light-transmitting material being arranged at intervals, and the shading material being arranged on the periphery of the first light-transmitting material and the periphery of the second light-transmitting material; extruding the first light-transmitting material, the second light-transmitting material and the shading material to obtain a composite bar; and treating the composite bar, and obtaining the cover plate. According to the preparation method of the cover plate provided by the embodiment of the invention, the first light-transmitting material, the second light-transmitting material and the shading material are combined together by adopting an extrusion method to obtain the cover plate, and the shading material is arranged between the first light-transmitting material and the second light-transmitting material in the cover plate for blocking; light crosstalk between the first light-transmitting material and the second light-transmitting material can be avoided.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to a method for preparing a cover, the cover and electronic equipment. Background technique [0002] Optical components inside electronic devices can be used to detect environmental parameters or human body parameters. For example, there is a blood oxygen detection function among the health functions of smart watches. The current mainstream blood oxygen detection method is photoplethysmographic (PPG). The light-transmitting area of ​​the body enters the outside world, and then passes through the tissues and arteries and veins in the skin. Part of it is absorbed, and part of it is reflected back to the light sensor. The light signal received by the light sensor is converted into an electrical signal, and the blood oxygen data is obtained after conversion. [0003] The existing PPG structure generally includes a housing, the housing includes a back cover, the back cover...
