Embodiment Construction

[0021] As mentioned in the background, in the prior art, the capacitive fingerprint imaging technology is mostly integrated with the display module of the self-luminous display panel.

[0022] In order to solve the above-mentioned technical problem, the present invention provides a display module, through the use of the photosensitive device integrated in the liquid crystal display panel and the point-shaped image-picking light source, under the premise of ensuring the display effect, a clear image can be obtained. Fingerprint images, so as to better realize the integration of fingerprint recognition and image display functions.

[0023] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] refer to figure 1 , shows a schematic cross-sectional structure diagram of the first embodiment of the...

Abstract

The invention discloses a display module. The display module comprises a liquid crystal display panel, a protecting layer and a punctiform image collecting light source, wherein the liquid crystal display panel comprises multiple displaying pixel units, the displaying pixel units comprise permeable areas and non-permeable areas, and the non-permeable areas of part of the displaying pixel units areprovided with light sensing members, the protecting layer is located above the liquid crystal display panel, the face, facing the surface of the liquid crystal display panel, of the protecting layeris a back face, a groove is formed in the back face, the groove is located on one side of the liquid crystal display panel, at least part of the punctiform image collecting source is located in the groove, the face, back to the surface of the liquid crystal display panel, of the protecting layer is a sensing detecting face, light generated by the punctiform image collecting light source enters theprotecting layer from at least one surface of the groove, the light is transmitted to the sensing detecting surface through the protecting layer to form reflecting light which carries fingerprint information on the sensing detecting surface, and the reflecting light is collected by a light sensing member to obtain a fingerprint image. The display module has the advantages that under the premise that a displaying effect is ensured, a clear fingerprint image is obtained to well achieve the integration of fingerprint recognition and image display functions.

Description

technical field [0001] The invention relates to the field of optical fingerprint identification, in particular to a display module. Background technique [0002] Fingerprint imaging recognition technology is to collect the fingerprint image of the human body through the fingerprint sensor, and then compare it with the existing fingerprint imaging information in the system to judge whether it is correct or not, and then realize the technology of identity recognition. Due to its ease of use and the uniqueness of human fingerprints, fingerprint recognition technology has been widely used in various fields. For example, security inspection areas such as public security bureaus and customs, building access control systems, and consumer products such as personal computers and mobile phones, etc. [0003] The realization of fingerprint imaging recognition technology includes optical imaging, capacitive imaging, ultrasonic imaging and other technologies. Relatively speaking, the o...
