DETAILED DESCRIPTION

The invention now will be described more fully hereinafter with reference to the accompanying drawings, in which various embodiments are shown. This invention may, however, be embodied in many different forms, and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like reference numerals refer to like elements throughout.

It will be understood that when an element is referred to as being “on” another element, it can be directly on the other element or intervening elements may be present therebetween. In contrast, when an element is referred to as being “directly on” another element, there are no intervening elements present.

It will be understood that, although the terms “first”, “second”, etc. may be used herein to describe various components, these components should not be limited by these terms. These terms are only used to distinguish one component from other components. Thus, “a first component” discussed below could be termed a second component without departing from the teachings herein.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms, including “at least one,” unless the content clearly indicates otherwise. “Or” means “and/or.” As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. It will be further understood that the terms “comprises” “comprising”, “includes” and/or “including” when used herein, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

Furthermore, relative terms, such as “lower” or “bottom” and “upper” or “top,” may be used herein to describe one element's relationship to another element as illustrated in the Figures. It will be understood that relative terms are intended to encompass different orientations of the device in addition to the orientation depicted in the Figures. For example, if the device in one of the figures is turned over, elements described as being on the “lower” side of other elements would then be oriented on “upper” sides of the other elements. The exemplary term “lower,” can therefore, encompasses both an orientation of “lower” and “upper,” depending on the particular orientation of the figure. Similarly, if the device in one of the figures is turned over, elements described as “below” or “beneath” other elements would then be oriented “above” the other elements. The exemplary terms “below” or “beneath” can, therefore, encompass both an orientation of above and below.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

Exemplary embodiments are described herein with reference to cross section illustrations that are schematic illustrations of idealized embodiments. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, embodiments described herein should not be construed as limited to the particular shapes of regions as illustrated herein but are to include deviations in shapes that result, for example, from manufacturing. For example, a region illustrated or described as flat may, typically, have rough and/or nonlinear features. Moreover, sharp angles that are illustrated may be rounded. Thus, the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the precise shape of a region and are not intended to limit the scope of the present claims.

Hereinafter, embodiments of the disclosure will be described in detail with reference to the accompanying drawings.

The sensor scan signals may have voltage levels predetermined to turn on transistors which are supplied with the sensor scan signals.

For connection with the sensor scan lines SS0 to SSn, the sensor scan driver 114 may be directly mounted on the substrate 112 or may be coupled to the substrate 112 through a separate component such as a flexible printed circuit board (“FPCB”).

The read-out circuit 115 may receive signals (e.g., currents), which is output from the sensor pixels SP, through the output lines O1 to Om.

In one embodiment, for example, when the sensor scan driver 114 sequentially supplies the sensor scan signals, the sensor pixels SP may be selected on a line-by-line basis, and the read-out circuit 115 may sequentially receive currents output from the sensor pixels SP selected on a line basis.

In such an embodiment, the read-out circuit 115 may recognize current touch information by sensing a change in current of the sensor scan signals from the sensor pixels SP.

The first electrode 332 and the second electrode 333 of the third transistor T3 may be connected or coupled to other components through respective contact holes CH6 and CH7.

In such an embodiment, the third transistor T3 may be turned on when a sensor scan signal is supplied to the (i-1)-th sensor scan line SSi-1. When the third transistor T3 is turned on, the voltage of the sensor electrode 300 may be initialized to the reference voltage Vcom.

The capacitor electrode 350 may be disposed to overlap the sensor electrode 300, and may thus form a capacitor with the sensor electrode 300.

The capacitor electrode 350 may be connected or coupled to the i-th sensor scan line SSi. In one embodiment, for example, the capacitor electrode 350 may be connected or coupled to the i-th sensor scan line SSi through the gate electrode 324 of the second transistor T2.

FIGS. 6A and 6B are diagrams illustrating a change in capacitance of a second capacitor related to the sensor electrode 300 depending on a ridge and a valley of a fingerprint. In particular, FIG. 6A illustrates a state in which a ridge 410 of a finger 400 is located on a sensor pixel, and FIG. 6B illustrates a state in which a valley 420 of the finger 400 is located on the sensor pixel.

Referring to FIGS. 6A and 6B, the sensor electrode 300 and the capacitor electrode 350 may form a first capacitor Cl. The sensor electrode 300 and the capacitor electrode 350 may be spaced apart from each other, and at least one insulating layer (not illustrated) may be interposed therebetween.

When the finger 400 of the user is placed on the sensor pixel to recognize a fingerprint, the sensor electrode 300 and the finger 400 may form a second capacitor C2.

In such an embodiment, the second capacitor C2 is a variable capacitor, the capacitance of which may vary depending on whether the ridge 410 or valley 420 of the fingerprint is placed on the sensor electrode 300.

Since the distance between the ridge 410 and the sensor electrode 300 is shorter than the distance between the valley 420 and the sensor electrode 300, the capacitance of the second capacitor C2 in the state where the ridge 410 is placed on the sensor electrode 300, as shown in FIG. 6A, and the capacitance of the second capacitor C2 in the state where the valley 420 is placed on the sensor electrode 300, as illustrated in FIG. 6B, may differ from each other.

Referring to FIGS. 3 to 6A and 6B, since a change in the capacitance of the second capacitor C2 influences the output current Io of the sensor pixel SP, the read-out circuit 115 may detect or recognize the fingerprint of the user by sensing a change in the output current Io.

A sensor protective layer (not shown) may be disposed on the sensor electrode 300. The sensor protective layer (not shown) may be used as a surface to be touched by the user.

The read-out circuit 115 may detect or recognize the palm print of the user in the foregoing manner.

In an embodiment, as described above, the sensor electrode 300 and the capacitor electrode 350 may define or constitute the first capacitor C1. The first transistor T1, the second transistor T2 and the third transistor T3 may define or form a sensor circuit 200.

The second capacitor C2, which is a variable capacitor, may be formed by the sensor electrode 300 and the finger 400, as described above with reference to FIGS. 6A and 6B. Here, the capacitance of the second capacitor C2 may change depending on the distance between the sensor electrode 300 and the finger 400, information about whether the valley or ridge of a fingerprint is placed on the sensor electrode 300, the magnitude of pressure applied by a touch or the like may be obtained by sensing the change in capacitance of the second capacitor C2.

The first transistor T1 may control a current flowing to the j-th output line Oj. For this operation, the first transistor T1 may be coupled between the j-th output line Oj and the second transistor T2.

In one embodiment, for example, the second transistor T2 may include a first electrode connected or coupled to the j-th reference voltage line Pj, a second electrode connected or coupled to the first electrode of the first transistor T1, and a gate electrode connected or coupled to the i-th sensor scan line SSi.

Therefore, the second transistor T2 may be turned on when a sensor scan signal is supplied to the i-th sensor scan line SSi. When the second transistor T2 is turned on, a reference voltage Vcom may be applied to the first electrode of the first transistor T1.

The third transistor T3 may be coupled between the j-th reference voltage line Pj and the sensor electrode 300.

In such an embodiment, the third transistor T3 may be coupled between the second node N2 and the j-th reference voltage line Pj, and the gate electrode thereof may be connected or coupled to the (i-1)-th sensor scan line SSi-1.

Therefore, the third transistor T3 may be turned on when a sensor scan signal is supplied to the (i-1)-th sensor scan line SSi-1. When the third transistor T3 is turned on, the voltage of the sensor electrode 300 may be initialized to the reference voltage Vcom.

The capacitor electrode 350 may be disposed to overlap the sensor electrode 300, and may then form the first capacitor C1 with the sensor electrode 300.

The capacitor electrode 350 may be connected or coupled to the i-th sensor scan line SSi.

Thus, the first capacitor C1 may be coupled between the second node N2 and the i-th sensor scan line SSi.

The second capacitor C2 may be connected or coupled to the second node N2.

The first node N1 is a node to which the first electrode of the first transistor T1 and the second electrode of the second transistor T2 are commonly connected, and the second node N2 is a node to which the sensor electrode 300, the gate electrode of the first transistor T1 and the second electrode of the third transistor T3 are commonly connected.

Therefore, during the first period P1, the third transistor T3 may remain turned on, and the second node N2 may be initialized to the reference voltage Vcom which is applied from the j-th reference voltage line Pj.

Thereafter, during a second period P2, the sensor scan signal may be supplied to an i-th sensor scan line SSi.

Therefore, during the second period P2, the second transistor T2 may remain turned on, and the current Io may flow from the j-th reference voltage line Pj to the j-th output line Oj through the second transistor T2 and the first transistor T1.

In an embodiment, the first transistor T1 may control the amount of output current Io in response to a gate voltage (i.e., voltage applied to the second node N2).

In one embodiment, for example, the output current Io may change depending on the gate voltage Vg of the first transistor T1, and the gate voltage Vg of the first transistor T1 may be determined by the following equation: Vg=Vcom+{Vc1/(Vc1+Vc2)}×Vs.

In the equation above, Vcom denotes the reference voltage, Vc1 denotes the capacitance of the first capacitor C1, Vc2 denotes the capacitance of the second capacitor C2, and Vs denotes a change in the voltage of the first sensor scan signal that is supplied to the i-th sensor scan line SSi.
