Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Like reference numerals throughout the specification denote substantially identical components. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following description, a detailed description of known technologies or configurations related to the present invention will be omitted when it is determined that the gist of the present invention may be unnecessarily obscured. In addition, the component names used in the following description may be selected in consideration of easiness of specification, and may be different from the parts names of actual products.

FIG. 4 is a view illustrating a structure of a multi-view display device according to an embodiment of the present invention. Referring to FIG. 4, the multi-view display according to the present invention includes a cell panel 100 and a lenticular lens film (LLS).

The multi-view display device according to the present invention can be implemented on the basis of a flat panel display device. Hereinafter, the cell panel 100 is illustrated as a display panel of a liquid crystal display device, but is not limited thereto.

The cell panel 100 includes a pixel array 104 in which data wirings and gate wirings (or scan wirings) are orthogonal and pixels are arranged in a matrix form. Each of the pixels may include sub-pixels of different colors for color implementation.

As shown in Fig. 4, in the case of reproducing different view images at the left viewing angle, the center viewing angle, and the right viewing angle, the pixel array 104 can be divided into three pixel groups. The pixel array 104 includes a first pixel group L for displaying an image of a first video content (hereinafter referred to as a " first view image ") (Left View), an image of a second video content (Hereinafter, referred to as "second view image") representing a second viewpoint image, a second pixel group C displaying a second viewpoint image (center view) And displays the images of different video contents including the pixel group R and the like.

The lenticular lens film (LLS) uses the lenticular lens surface to separate the light path of the first view image, the light path of the second view image, and the light path of the third view image by viewing angle. A first pixel belonging to the first pixel group L, a second pixel belonging to the second pixel group C, a third pixel belonging to the third pixel group (L) within one lens pitch (P lens ) of the lenticular lens film (LLS) R) is disposed in the second pixel. The first pixel displays a first view image, and light passing through the first pixel is propagated at a first viewing angle. The second pixel displays a second view image, and the light passing through the second pixel propagates at a second viewing angle. The third pixel displays the third view image, and the light passing through the third pixel propagates to the third viewing angle. The first pixel is visible to the viewer located at the left viewing angle through the lens surface. The second pixel is visible to a viewer located at a central viewing angle through the lens surface. The third pixel is visible to the viewer located at the right viewing angle through the lens surface. Accordingly, the viewer can view the first to third view images according to the viewing angle, and a plurality of viewers having different viewing angles can simultaneously view the first to third view images.

Since the lenticular lens film LLS does not block light, the brightness of the first to third view images can be increased as compared with a barrier. Accordingly, since the multi-view display device according to the present invention can increase the brightness, the cost and the power consumption of a back light unit (BLU), which is not shown, can be reduced and can be used as an outdoor display device.

The cell panel 100 includes a top plate and a bottom plate bonded together by a sealant. A liquid crystal layer is formed between the upper plate and the lower plate. A color filter array may be formed on the first surface of the top plate that is in contact with the liquid crystal layer.

The color filter array includes a color filter and a pixel black matrix formed on the inner surface or the first surface of the upper substrate 103. A pixel black matrix is formed at the boundary between neighboring pixels to prevent optical interference between neighboring pixels. A slit black matrix (hereinafter referred to as "slit BM") 107 is formed on the outer surface or the second surface of the upper substrate 103.

The width of the slit BM 107 may vary depending on the model of the multi-view display device but must be greater than the width of the pixel black matrix of the pixel array 104 to block the light of the unwanted neighbor view image, Interference can be prevented. The slit BM 107 also provides an effect of preventing the interference of view images at neighboring viewing angles, thereby enlarging the viewing angle.

The slit BM 107 may be formed by a photolithography process, a screen printing process, or the like. The slit BM 107 intercepts light diffused at a wide angle to prevent interference between neighboring view images displayed at neighboring viewing angles. The upper polarizer 102 is bonded to the second surface of the upper substrate 103. The slit BM 107 is covered with the upper polarizer 102. The lenticular lens film (LLS) is adhered to the outer surface of the upper polarizing plate (102) by the adhesive layer (101).

The lower panel of the cell panel 100 includes a TFT array formed on the upper surface or the inner surface of the lower substrate 105. The TFT array includes data wirings and gate wirings, TFTs formed at intersections of data wirings and gate wirings, pixel electrodes defined in a matrix form by data wirings and gate wirings, Storage capacitors (Cst), and the like. The lower polarizer 106 is bonded to the back or outer surface of the lower substrate 105.

An alignment film for forming a pre-tilt angle of the liquid crystal is formed on a surface of the upper substrate 103 and the lower substrate 105 which is in contact with the liquid crystal layer. A spacer for maintaining a cell gap of the liquid crystal layer is formed between the upper substrate 103 and the lower substrate 105.

A cell panel driving unit not shown includes a data driving circuit, a gate driving circuit, and a timing controller. The data driving circuit converts the digital video data of the first to third view images input from the timing controller into analog gamma voltages to generate data voltages and supplies the data voltages to the data lines. The gate driving circuit supplies a gate pulse (or a scan pulse) synchronized with the data voltage supplied to the data lines under the control of the timing controller to the gate lines, and sequentially shifts the gate pulse. The timing controller transmits the digital video data of the first to third view images to the data driving circuit, and controls the operation timing of the data driving circuit and the gate driving circuit.

When a lenticular lens film (LLS) is attached to the cell panel 100 in the multi-view display device having such a structure, it is possible to provide an image with good quality so as to match the designed intentions by aligning accurately. That is, the first pixel belonging to the first pixel group L, the second pixel belonging to the second pixel group C, and the third pixel belonging to the second pixel group C in the one lens pitch (P lens ) of the lenticular lens film (LLS) The third pixels belonging to the group R must be accurately arranged to perform image separation correctly.

Hereinafter, specific embodiments will be described with reference to FIGS. 5 to 7, in which the lenticular lens film (LLS) is accurately attached to the cell panel 100 in the multi-view display apparatus according to the present invention. Further, the structures of the multi-view display device having unique characteristics according to each of these embodiments will be described.

In general, a lenticular lens film (LLS) has a structure in which a plurality of semi-cylindrical lenses (UL) are arranged on one base film (BF). Here, the semi-cylindrical lens UL means a portion occupying one lens pitch (P lens ) in FIG. The lenticular lens film (LLS) is produced by cutting the surface of the base film (BF) and inserting semi-cylindrical lenses (UL). Among the thus prepared lenticular lens films (LLS), the regions where the shapes of the semicylindrical lenses (UL) are intact are selectively cut and then adhered to the cell panels.

In this adhesion process, the unit semi-cylindrical lens (UL) of the lenticular lens film (LLS) must be arranged so as to exactly coincide with the arrangement of the first pixel column, the second pixel column and the third pixel column of the pixel array 104. However, it is not easy to align the arbitrarily cut lenticular lens film (LLS) with the pixels of the pixel array 104 accurately.

First, a first embodiment of the present invention will be described with reference to FIG. 5 is a view showing a structure of a lenticular lens film according to a first embodiment of the present invention, showing a plan view on the right side and a sectional view on the left side.

Referring to FIG. 5, the lenticular lens film LLS according to the first embodiment includes display area parts LA and non-display area parts NA located on both sides of the display area part LA. An alignment mark AM is displayed at the boundary between the display area LA and the display area LA. In particular, a plurality of semi-cylindrical lenses (UL) are arranged in the display area LA. On the other hand, no lens pattern is formed in the non-display area parts NA. The alignment mark AM is preferably formed of a black material such as black matrix or slit BM 107.

The alignment mark AM of the lenticular lens film LLS according to the first embodiment can be aligned and aligned after aligning with the outermost black matrix of the cell panel 100. [ Then, the unit semicylindrical lenses (UL) of the lenticular lens film (LLS) can be precisely arranged so as to coincide with the arrangement of the pixel array (104).

In the first embodiment, a lenticular lens film (LLS) in which a lenticular lens pattern is not present in the non-display area NA and a lenticular lens pattern exists only in the display area LA is presented. However, when considering a method of forming a lenticular lens pattern, it is considerably difficult to form the lenticular lens pattern only in a part. Hereinafter, with reference to FIG. 6, a more preferred embodiment considering the step of forming the lenticular lens pattern will be described. 6 is a view showing the structure of a lenticular lens film according to the second embodiment, showing a plan view on the right side and a sectional view on the left side.

Referring to FIG. 6, the lenticular lens film LLS according to the second embodiment includes display area parts LA and non-display area parts NA located on both sides of the display area part LA. A lenticular lens pattern having the same pitch is formed in both the display region LA and the non-display region NA. The alignment mark AM is displayed in the lenticular lens patterns formed in the non-display area NA. The alignment mark AM may be formed of a black material such as a black matrix or a slit BM 107 on the valley of the unit lenticular lens formed in the non-display area NA.

The formation of the lens pattern in both of the display region LA and the non-display region NA of the lenticular lens film LLS can be realized by forming the lens pattern having a good shape in the pixel array 104, So that it can be aligned with the other. For example, in the case of forming a lens pattern by cutting the surface of the base film BF, the rental pattern in a certain region of the edge portion may be damaged or uneven due to the apparatuses and environments used in the manufacturing process. Therefore, it is possible to define, as a display region LA, a portion which maintains a certain lens pattern without being damaged, and a certain number of lens patterns outside the outermost lens pattern of the display region LA to a non- Can be defined. An alignment mark AM is displayed at an intermediate position of about three to five unit semicylindrical lenses UL having a relatively good pattern even in the non-display area NA.

The alignment marks AM of the lenticular lens film LLS according to the second embodiment can be aligned and aligned after being aligned with the outermost black matrix of the cell panel 100. [ Then, the unit semicylindrical lenses (UL) of the lenticular lens film (LLS) can be precisely arranged so as to coincide with the arrangement of the pixel array (104).

Alternatively, after the alignment marks AM of the lenticular lens film LLS according to the second embodiment are aligned with the outermost slit BM 107 of the cell panel 100, they can be cemented . As a result, the unit semi-cylindrical lenses (UL) of the lenticular lens film (LLS) can be precisely arranged so as to coincide with the arrangement of the pixel array (104).

In this case, at least three or more pixel arrays 104 may be disposed outside the outermost slit BM 107. This is because the slit BM 107 is formed not at the boundary of all the pixel arrays 104 but at one lens pitch P including three pixel columns (the first pixel column, the second pixel column and the third pixel column) one for each lens . Therefore, even if the alignment mark AM is aligned with the outermost slit BM 107, the unit lenticular lens UL can be normally disposed on the pixel array 104 disposed outside the alignment mark AM.

Next, another method of aligning the lenticular lens film LLS and the cell panel 100 will be described with reference to FIG. Fig. 7 shows the structure of a lenticular lens film according to the third embodiment, showing a plan view on the right side and a cross-sectional view on the left side.

Referring to FIG. 7, the lenticular lens film LLS according to the third embodiment includes non-display area parts NA located on both sides of the display area LA and the display area LA. A lenticular lens pattern is formed on both the display area LA and the non-display area NA. For example, the lenticular lens film LLS according to the third embodiment includes the first unit semi-cylindrical lenses UL1 having the first pitch LP1 value formed in the non-display area NA, LA) having a second pitch (LP2) value formed in the second unit semi-cylindrical lenses UL2. In particular, the second pitch LP2 value may be greater than the first pitch LP1 value. In the third embodiment, the alignment mark AM may or may not be included in the boundary between the non-display area NA and the display area LA. The case in which the alignment mark AM is included is the same as in the first and second embodiments, and thus a detailed description thereof will be omitted.

The reason why the alignment mark AM may not be included in the third embodiment is that since the first pitch LP1 and the second pitch LP2 have different sizes, It is possible to accurately detect between the first pitch LP1 and the second pitch LP2. Therefore, even if there is no special alignment mark AM, it is possible to distinguish the non-display area NA and the display area LA.

In the lenticular lens film LLS according to the third embodiment, after the boundary between the non-display area NA and the display area LA is aligned with the outermost black matrix of the cell panel 100, . Then, the unit semicylindrical lenses (UL) of the lenticular lens film (LLS) can be precisely arranged so as to coincide with the arrangement of the pixel array (104).

Alternatively, a lens pattern of a predetermined number of second unit semi-cylindrical lenses UL2 after the boundary between the non-display area NA and the display area LA toward the display area LA may be formed on the cell panel 100, After aligning them to match the outermost black matrix of FIG. Alternatively, a lens pattern next to a certain number of second unit semicylindrical lenses UL2 from the boundary of the non-display area NA and the display area LA toward the display area LA may be formed on the cell panel 100 , And then they can be joined together.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Therefore, the present invention should not be limited to the details described in the detailed description, but should be defined by the claims.

NA: non-display area AM: alignment mark
UL: unit semi-cylindrical lens UL1: first unit semi-cylindrical lens
