Problems solved by technology

[0004] However, in practical applications, the light received by the photosensitive device 93 is severely lost due to scattering or reflection in the propagation process, and the adjacent photosensitive device 93 is also easily triggered by mistake for the same reason, resulting in the sensitivity of the photosensitive device 93 not reaching the ideal state.

Abstract

The invention discloses a cover plate, a manufacturing method thereof and a display panel. The cover plate comprises a first substrate, a light condensation structure and a flat layer, wherein the light condensation structure is arranged on the first substrate, and the flat layer covers the light condensation structure and the substrate; and the light condensation structure is made of first photoresist, the flat layer is made of second photoresist, a refractive index of the second photoresist is smaller than that of the first photoresist, and the flat layer covers the light condensation structure and the substrate. According to the cover plate, the manufacturing method thereof and the display panel, the sensitivity and the precision of a photosensitive device can be improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a cover plate, a manufacturing method thereof, and a display panel. Background technique [0002] With the development of display technology, additional functions such as automatic color temperature adjustment of display panels, photo copying, remote light-sensing interaction, and optical fingerprint recognition have become important technical means to increase the added value of display products and increase product differentiation. [0003] figure 1 It is a schematic structural diagram of an existing display device. Such as figure 1 As shown, the existing display device includes a display panel 91 , a backlight module 92 and a photosensitive device 93 . In order to realize the above additional functions, the photosensitive device 93 is generally integrated on the display panel 91 . [0004] However, in practical applications, the light received by the photosensit...
