First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the electronic device or the proximity sensor 141 near the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched.

Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

The display unit 151 may include a flat panel display module such as a liquid crystal display (LCD) module, a thin film transistor-liquid crystal display (TFT) module, or an organic light emitting diode (OLED)

The window glass 151a may be positioned on the front surface of the display unit 151 to protect the display unit 151. [ The window glass 151a may be formed to have two or more curvatures and the window glass 151a of Figure 3 may have different curvatures in the first area D1, the second area D2, and the third area D3 And illustrates the applied state.

The window glass 151a may have a curve shape in which the upper and lower ends of the window glass 151a face the entire area. Here, the second area D2, which is the center area, may be formed to have a smaller curvature than the upper and lower ends of the area for displaying a screen. The first region D1 and the third region D3 extending from both ends of the second region D2 may be formed to have different curvatures from the second region D2. The curvature applied to the window glass 151a, the number of curvatures, the direction of the curvature, and the like can be variously set according to the design method of the designer.

The image correction unit (not shown) corrects at least any one of luminance non-uniformity and image distortion caused by the difference in distance between the window glass 151a and the display unit 151. [ The screen correction unit includes a prism pattern layer formed on the window glass 151a for increasing light transmittance, a control unit for controlling the brightness of each area of the display unit 151 and controlling the shape of the image displayed on the display unit 151 180), and the like.

4 and 5 are views for explaining the curvature structure of the window glass 151a. Fig. 4 is a side view of the window glass 151a and an enlarged view of the recessed area. Fig. 5 is a cross- And an enlarged view of the lumbar region.

Referring to FIG. 4, the window glass 151a may have a curve shape in which the upper and lower ends of the window glass 151a face the front side of the central region, and the window glass 151a may have a curved shape in the first region D1, the second region D2, Different curvatures can be applied. Referring to the enlarged view of the first area D1 and the second area D2, when the first area D1 has a curvature larger than that of the second area D2, It may have a shape protruding further toward the front than the area D2.

5 is an enlarged view of the first area D1 and the second area D2 when the curvature of the first area D1 is set smaller than the window glass 151a of FIG.

Referring to FIG. 5, when the curvature of the first region D1 is smaller than that of FIG. 4, it may have a shape that is less protruded than the first region D1 of FIG. As described above, the curvature of the window glass 151a can be variously changed according to the design method of the designer.

6 to 8 are views for explaining the state of bonding between the window glass 151a of the electronic apparatus and the display unit 151 according to the present invention.

Referring to FIG. 6, the electronic apparatus according to the present invention includes a display unit 151 and a window glass 151a disposed on the front surface of the display unit 151 and having two or more curvatures.

The window glass 151a may have different curvatures for the first area D1, the second area D2 and the third area D3. The window glass 151a illustrated in FIG. And a curve shape in which the lower end faces the front side.

The display unit 151 may include a flat panel display module such as a liquid crystal display (LCD) module, a thin film transistor-liquid crystal display (TFT) module, or an organic light emitting diode (OLED)

If the window glass 151a having a curvature is stacked on the flat display portion 151, the interval between the display portion 151 and the window glass 151a may be different according to each point. For example, in the case of the point A where the curvature of the window glass 151a fluctuates, the interval between the window glass 151a and the display unit 151 may be widened or narrowed as shown in FIG. 8, the distance between the window glass 151a and the display unit 151 is relatively small as shown in FIG. 8, at the end B of the display unit 151. In this case, Can be expanded. In addition, when the curvature of the window glass 151a is large, the interval between the window glass 151a and the display unit 151 in the central area becomes narrower and the interval in the outer area can be widened.

As described above, when a flat display portion 151 and a window glass 151a having a curvature are bonded to each other, a liquid type adhesive such as an optical transparent adhesive resin (OCR) can be used. In the case of using the OCR method, even when the gap between the display unit 151 and the window glass 151a is irregular, it is possible to easily adhere and to fill the empty space between the display unit 151 and the window glass 151a, It is possible to obtain the effect of reducing the difference in refractive index between the two.

On the other hand, the interval between the display unit 151 and the window glass 151a may be different according to each point. When the first area D1 and the second area D2 which are both ends of the window glass 151a are not the screen display areas, there is a low possibility that the change in the interval with the display part 151 becomes a problem, When the interval between the window glass 151a and the display unit 151 is widened, the luminance of the corresponding region is lowered, and when the interval is narrowed, the luminance of the corresponding region may be increased. In addition, the light emitted from the display unit 151 may be transmitted through the curved window glass 151a, and the direction of light transmission may be changed, so that the screen displayed on the display unit 151 may be distorted. Thus, the screen correction unit uniformly displays the brightness of the display unit 151 and prevents the image from being distorted even if the interval between the window glass 151a and the display unit 151 changes.

9 and 10 are diagrams for explaining a method of processing a window glass 151a having a multiple curvature of an electronic apparatus according to the present invention, in which the window glass 151a is provided with a screen correction unit.

A prism pattern layer (P) can be formed on the window glass (151a) as a screen correcting unit. The prism structure can increase the amount of light by verticalizing the traveling direction of light. Accordingly, by forming the prism pattern layer P in the area where the interval between the display part 151 and the window glass 151a is wide, the light amount of the corresponding area can be increased to improve the brightness.

FIG. 9 illustrates a method of processing the window glass 151a when a predetermined curvature is realized after the prism pattern layer P is formed on the flat window glass 151a.

(a), a prism pattern layer P is formed in a region of the flat window glass 151a which is in contact with the display portion 151. [ The prism pattern layer P may be formed by a laser processing method. In addition, various techniques such as bonding a sheet on which the prism pattern layer P is formed may be applied.

Here, the prism pattern layer P must transmit light of the display portion 151 vertically. Accordingly, the vertex angle may be formed so as to face the center portion or the outer frame portion according to the curvature to be applied to the window glass 151a. In addition, the angle of the apex angle can be improved by 40 to 60 degrees to improve the vertical effect of light.

(b), a curvature is implemented in a flat window glass 151a on which a prism pattern layer P is formed. Accordingly, the apex angle of the prism pattern layer P is vertically arranged, and the light emitted from the display unit 151 can be vertically transmitted regardless of the curvature applied to the window glass 151a. The amount of light transmitted through the window glass 151a is increased due to the vertical direction of light propagation, and thus the brightness of the region where the prism pattern layer P is formed can be improved.

10 illustrates a processing method of forming the prism pattern layer P on the window glass 151a on which the curvature is implemented.

the prism pattern layer P may be formed later as shown in (b) after first implementing the curvature in the window glass 151a, as shown in FIG.

a prism pattern layer P may be formed in a region of the window glass 151a having curvature that is in contact with the display portion 151 and the angle of the apex angle of the prism pattern layer P may be 40 ~ 60 degrees, and the vertical effect of light can be improved.

The prism pattern layer P formed on the window glass 151a may be formed by a laser processing method and various techniques such as bonding a sheet on which the prism pattern P is formed may be applied.

In addition to the method of forming the prism pattern layer P on the window glass 151a, a technique of coating the window glass 151a may be applied to adjust the brightness. For example, when the brightness of the window glass 151a is to be improved, the high-refraction coating process can be performed on the region. In the high refractive index coating process, the brightness of the coated region can be improved by a coating method using materials such as TiO 2 and Ag ultrafine particles. On the other hand, when it is necessary to lower the luminance, a low refraction coating process can be applied to the area. In the low refraction coating process, the brightness of the coated region can be reduced by a coating method using a material such as SiO2.

11 and 12 are diagrams illustrating a distribution of curvature centers of a display of an electronic apparatus related to the present invention. The center of curvature is the center of the curvature source.

Referring to FIG. 11, the center of curvature of the electronic device related to the present invention may exist in the upper, middle, and lower regions in the front region of the window glass 151a. Since the center of curvature is distributed in the front area of the window glass 151a, the window glass 151a can have a concave silhouette in the front direction.

Further, as shown in Fig. 12, the center of curvature may be located in the front and rear regions of the window glass 151a, respectively. When the center of the curvature is located on the front side of the window glass 151a, the window glass 151a has a concave silhouette in the front direction. When the center of curvature is located on the rear side of the window glass 151a, And a convex silhouette.

The central distribution of the curvatures shown in Figs. 11 and 12 is only an example, and the number of curvatures and the position of the center can be arbitrarily changed by the designer.

13 to 15 are perspective views of a display of an electronic apparatus according to the present invention.

13 illustrates the shape of the window glass 151a when the center of curvature is located in the front region and the rear region of the window glass 151a, respectively. Referring to FIG. 13, since the center of the curvature of the upper region of the window glass 151a is located on the front surface of the window glass 151a, the corresponding region has a concave silhouette in the front direction. Since the center of curvature of the lower end region of the window glass 151a is located on the rear side of the window glass 151a, the window glass 151a has a convex silhouette in the front direction. Accordingly, the overall shape of the window glass 151a may be formed such that the upper end thereof is concave and the lower end thereof is convex.

14 illustrates the shape of the window glass 151a when the center of curvature is located in the front area of the window glass 151a. Referring to FIG. 14, when the center of curvature is located on the entire surface of the window glass 151a, the window glass 151a has a concave silhouette in the front direction.

15 illustrates the shape of the window glass 151a when the center of curvature is located in the rear area of the window glass 151a. Referring to FIG. 15, when the center of curvature is located on the rear surface of the window glass 151a, the window glass 151a has a convex silhouette in the front direction.

16 is an icon display state diagram of an electronic device related to the present invention, and illustrates an icon (I) display state when a control unit 180 (FIG. 1) for controlling the display unit 151 includes a screen correction unit.

When the window glass 151a having a curvature and the flat display unit 151 are bonded to each other, the brightness may become uneven or the image may be distorted due to the difference in the distance between the window glass 151a and the display unit 151. [

The control unit 180 can control the display unit 151 such that the luminance of the corresponding region is higher for the region where the interval between the window glass 151a and the display unit 151 is relatively wide and the luminance is lowered. The control unit 180 can control the display unit 151 so that the luminance of the corresponding region is lowered in a region where the interval between the window glass 151a and the display unit 151 is relatively narrow and the luminance is high. In this manner, the controller 180 can solve the non-uniformity of brightness by increasing or decreasing the brightness of each area of the display unit 151 as necessary.

When the curvature is applied to the window glass 151a, the light emitted from the display unit 151 can be transmitted through the curved window glass 151a, and the direction of light transmission can be changed. It can be distorted.

16 (a) to 16 (d) are display state diagrams of the icon I in the absence of the screen correction section, and (a ') to The display state of the icon I is illustrated.

(a), when the window glass 151a is flat, the icon I displayed on the display unit 151 can be displayed without distortion. Accordingly, the control unit 180 displays the icon I as it is, as in (a ').

(b), when the window glass 151a is convex, the icon I displayed on the display unit 151 may be enlarged and displayed in a larger size than the actual size. Accordingly, the controller 180 displays an icon I having a size smaller than the original state as shown in (b '), so that the icon I displayed through the window glass 151a is normally displayed.
