Certain terms are used throughout the description and following claims to refer to particular components. As one skilled in the art will understand, electronic equipment manufacturers may refer to a component by different names. This document does not intend to distinguish between components that differ in name but not function. In the following description and in the claims, the terms “include”, “comprise” and “have” are used in an open-ended fashion, and thus should be interpreted to mean “include, but not limited to...”. Thus, when the terms “include”, “comprise” and/or “have” are used in the description of the present disclosure, the corresponding features, areas, steps, operations and/or components would be pointed to existence, but not limited to the existence of one or a plurality of the corresponding features, areas, steps, operations and/or components.
The directional terms used throughout the description and following claims, such as: “on”, “up”, “above”, “down”, “below”, “front”, “rear”, “back”, “left”, “right”, etc., are only directions referring to the drawings. Therefore, the directional terms are used for explaining and not used for limiting the present disclosure. Regarding the drawings, the drawings show the general characteristics of methods, structures, and/or materials used in specific embodiments. However, the drawings should not be construed as defining or limiting the scope or properties encompassed by these embodiments. For example, for clarity, the relative size, thickness, and position of each layer, each area, and/or each structure may be reduced or enlarged.
When the corresponding component such as layer or area is referred to “on another component”, it may be directly on this another component, or other component (s) may exist between them. On the other hand, when the component is referred to “directly on another component (or the variant thereof)”, any component does not exist between them. Furthermore, when the corresponding component is referred to “on another component”, the corresponding component and the another component have a disposition relationship along a top-view direction, the corresponding component may be below or above the another component, and the disposition relationship along the top-view direction are determined by an orientation of the device.
It will be understood that when a component or layer is referred to as being “connected to” another component or layer, it can be directly connected to this another component or layer, or intervening components or layers may be presented. In contrast, when a component is referred to as being “directly connected to” another component or layer, there are no intervening components or layers presented. In addition, when the component is referred to “be coupled to/with another component (or the variant thereof)”, it may be directly connected to this another component, or may be indirectly connected (such as electrically connected) to this another component through other component(s).
The terms “about”, “substantially”, “equal”, or “same” generally mean within 20% of a given value or range, or mean within 10%, 5%, 3%, 2%, 1%, or 0.5% of a given value or range.
Although terms such as first, second, third, etc., may be used to describe diverse constituent elements, such constituent elements are not limited by the terms. These terms are used only to discriminate a constituent element from other constituent elements in the specification, and these terms have no relation to the manufacturing order of these constituent components. The claims may not use the same terms, but instead may use the terms first, second, third, etc. with respect to the order in which an element is claimed. Accordingly, in the following description, a first constituent element may be a second constituent element in a claim.
It should be noted that the technical features in different embodiments described in the following can be replaced, recombined, or mixed with one another to constitute another embodiment without departing from the spirit of the present disclosure.

In the present disclosure, the type of the fingerprint sensor is not limited. For instance, the type of the fingerprint sensor may be a capacitive fingerprint sensor, an optical fingerprint sensor, an ultrasonic fingerprint sensor or a fingerprint sensor with other suitable type.

In addition, since the first connection line 160 may be formed by printing, coating or adhering, the resolution (such as a line width) of the first connection line 160 may be restricted (for example, the lower resolution and/or the greater line width). Accordingly, in some embodiments, the electronic device 100 may optionally include a demultiplexer (DEMUX) disposed on the second substrate 140 and electrically connected between the third conductive line T3 and the first connection line 160. Since the demultiplexer may make one first connection line 160 provide signals for different third conductive lines T3 in different times, or make different third conductive lines T3 provide signals for one first connection line 160 in different times, the number of the first connection line(s) 160 may be less than the number of the third conductive lines T3.

The display component 122 can include a pixel electrode and a common electrode.
In some embodiments, the electronic device 100 may include the display panel 100D, and the electronic device 100 may further include a light converting layer (shown in the following figure), a light shielding layer (shown in the following figure), an optical layer, other suitable layer or a combination thereof.

The light shielding layer may include such as black photoresist, black ink, black resin, pigment, dye, other suitable material or a combination thereof, and the light shielding layer may be a single-layer structure or a multi-layer structure.
