[0051] Such as Figure 5 As shown, the preparation method of the circuit board may include the following steps.

[0052] Step 510 , coating the coating liquid of the waterproof layer 3 with light-transmitting properties on the substrate 1 , so that the coating liquid of the waterproof layer 3 covers the photosensitive components 2 on the substrate 1 .

[0053] Specifically, the coating solution of the waterproof layer 3 can be in direct contact with the photosensitive device 2 , and other film layers, such as the above-mentioned fixed layer 7 , can also be arranged between the coating solution of the waterproof layer 3 and the photosensitive device 2 .

[0054] In addition, the coating solution of the waterproof layer 3 can completely cover the photosensitive component 2, or partially cover the photosensitive component 2, that is, the coating solution of the waterproof layer 3 is only arranged on the optical path of part of the light.

Abstract

The invention provides a circuit board and a preparation method of the circuit board and relates to the technical field of display. The circuit board comprises a substrate, a photosensitive componentarranged on the substrate, and a waterproof layer coating the photosensitive component, wherein the waterproof layer has a light transmission characteristic, and the waterproof layer comprises a plurality of additive materials for improving the light transmission rate of the waterproof layer. According to the circuit board and the preparation method of the circuit board of the embodiments of the invention, the additive materials are introduced into the waterproof layer, so that the light transmission rate of the waterproof layer is increased, and therefore, the blocking effect of the waterproof layer on the sensing light of the photosensitive component is effectively reduced, and thus, the probability of photosensitive function failure caused by the fact that the photosensitive component cannot sense light is reduced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a circuit board and a method for preparing the circuit board. Background technique [0002] Currently, display devices, such as smart watches, smart phones, etc., have a problem of water ingress during use. Therefore, a waterproof component needs to be added to the display device to prevent water from affecting the display function of the display device. However, the addition of waterproof components will affect the functions of other components in the display device. For example, when the waterproof component is arranged on the optical path of the photosensitive device, it will affect the photosensitivity of the photosensitive device. [0003] Therefore, in the case of adding a waterproof component, how to avoid the influence of the waterproof component on the functions of other components becomes an urgent problem to be solved. Contents of the invention [0004]...
