(a), (b) shown in Figure 11 are for illustrating the sheet in the optical display device production system of present embodiment The figure of the cut off operation of part F11.

Sheet shaped piece F11 sizes for example more corresponding than with the appearance and size of optical display components P are slightly larger.Here, above-mentioned " with The corresponding size of appearance and size of optical display components P " refers to, when being bonded to optical display components P, not generating in reality Border uses the size of the upper redundance as problem.Sheet shaped piece F11 is more corresponding than with the appearance and size of optical display components P big It is small big, therefore cut off the redundance for becoming problem in actual use using disconnecting device 184.For example, being shown in optics The central portion of component P is provided with the display area of display image, has electric component installation in the end set of optical display components P Portion, the electric component mounting portion have multiple terminals for connections such as semiconductor chip, flexible printed wirings.In this case, Such as the optical component FO of the size in following region is cut out from sheet shaped piece F11, which is the viewing area of optical display components P More than the size in the domain and size region below of the outer shape of optical display components P (contour shape when vertical view), and It is the region for avoiding the funtion parts such as electric component mounting portion in optical display components P.

By sheet shaped piece F11 fit in the laminating apparatus of optical display components P for example with illustrate in the first embodiment Laminating apparatus 1 is same.In the present embodiment, it is provided with detection device on the transport path in the downstream side of the laminating apparatus 189 and disconnecting device 184.

Detection device 189 includes the photographic device 183 shot to the optical display components P for being fitted with sheet shaped piece F11. The cutting line WCL of photographed data of the detection device 189 based on photographic device 183, detection sheet shaped piece F11 (is intended to cut sheet shaped piece F11 Disconnected position).

Photographic device 183 for example crosses sheet shaped piece above the optical display components P for being placed in cut-out workbench 185 F11 shoots optical display components P.Base of the photographic device 183 for example to the optical display components P for being bonded sheet shaped piece F11 The image of the quadrangle of plate (such as colour filtering chip basic board) is shot.Detection device 189 for example to shooting gained photographed data into Row image procossing detects the position of the outer peripheral edge of substrate, comes the position of the outer peripheral edge as the cutting line WCL of sheet shaped piece F11 It detects.

The information of the cutting line WCL detected by detection device 189 is sent to control device 190.Control device 190 is based on The information of the cutting line WCL sent from detection device 189, controls disconnecting device 184 and cuts off sheet shaped piece along cutting line WCL F11.Second area FS quilts on the outside of the first area FB opposed with the display area of sheet shaped piece F11 and first area FB as a result, It cuts off, the optical component FO of target size (size that the specification based on optical display device is set) is cut out from sheet shaped piece F11.

To the cutting line WCL of each optical display components P detection sheet shaped pieces F11 conveyed on transport path.Thus, i.e., Just there are the deviations of size by each optical display components P, also can reliably be cut out from sheet shaped piece F11 and optical display components P The corresponding size of appearance and size optical component FO.

In the present specification, the big sheet shaped piece F11 of the optical component FO than target sizes are being fitted in into optics display unit After part P, the photographed data based on optical display components P cuts off the redundance of sheet shaped piece F11, and this mode is referred to as " window Mouth cutting mode ".It in the present embodiment, can be by the optical component of desirable size by using window cutting mode FO fits in the desirable position of optical display components P.By using window cutting mode, effect below can be obtained.

(1) in the case where sheet shaped piece to be bonded to optical display components P, it is contemplated that optical display components P and optics Fitting deviation (position offset) etc. of each dimensional discrepancy and optical component FO of component FO relative to optical display components P, will The optical component FO more slightly larger than original required size fits in optical display components P.However, in the method, it is aobvious in optics Show that the peripheral portion of the display area of component P is formed with to showing the extra region (frame region) without contribution, hinders equipment Miniaturization.Using window cutting mode, shot to being fitted with the optical display components P after sheet shaped piece F11, Photographed data based on shooting gained cuts off sheet shaped piece F11, therefore can reliably match the optical component FO of target sizes It is placed in target location.

(2) direction of the optic axis of sheet shaped piece F11 deviates due to foozle from the direction designed originally sometimes.In the feelings Under condition, the preferred direction of the optic axis of measured in advance sheet shaped piece F11 (optical member sheet F1), based on the measurement result come trimmer The opposite bonding position of shape part F11 and optical display components P, but when the size of sheet shaped piece F11 and the optical component as target FO it is in the same size when, such adjustment can not be carried out.In window cutting mode, by the sheet shaped piece bigger than optical component FO F11 fits in optical display components P, then cuts off the redundance of sheet shaped piece F11, therefore can carry out such adjustment.

For example, bonding position (opposite positions of the sheet shaped piece F11 relative to optical display components P can be determined as described below It sets).

First, as illustrated in fig. 12, multiple checkpoint CP are set in the width direction of optical member sheet F1, in each inspection The direction of the optic axis of optical member sheet F1 is detected at point CP.The opportunity of detection optic axis can be manufacture blank volume R1 (references Can also be during blank volume R1 rolls out optical member sheet F1 until carrying out hemisect when Fig. 1).Optical member sheet F1 The data of optics axis direction and the position of the position of the length direction of optical member sheet F1 and width direction deposit in association It is stored in storage device (not shown).

The data that control device 190 obtains the optic axis of each checkpoint CP from the storage device (are divided in the face of optic axis The inspection data of cloth), and detect the optical member sheet F1 (being cut into the region that line CL is divided) for the part for cutting out sheet shaped piece F11 The direction of average optic axis.

For example, as shown in Figure 12 B, the edge line EL angulations (offset in the direction for setting optic axis and sheet shaped piece F11 Angle) it is θ max, when minimum angle (smallest offset angle) is θ min, by the flat of peak excursion angle θ max and smallest offset angle θ min Mean value θ mid (=(θ max+ θ min)/2) are detected as mean deviation angle.Also, by the edge relative to sheet shaped piece F11 The direction that line EL forms mean deviation angle θ mid is detected as the direction of the average optic axis of sheet shaped piece F11.It needs It is bright, it is set for the deviation angle, such as by the direction for rotating gained counterclockwise relative to the edge line EL of sheet shaped piece F11 Just, the direction for rotating clockwise gained to be set as bearing to calculate.

Then, so that the direction of the average optic axis of the optical member sheet F1 detected by above-mentioned method relative to The mode for forming desirable angle on one side of the display area P4 of optical display components P, to determine sheet shaped piece F11 relative to light Learn the bonding position (opposite bonding position) of display unit P.For example, due to design specification by the side of the optic axis of optical component In the case of the direction for being set as in 90 ° relative to the monogon of display area P4, so that optical member sheet F1's is average Sheet shaped piece F11 is fitted in optical display components by the direction of the optic axis mode in 90 ° relative to the monogon of display area P4 P。

Later, using detection device 189 shown in (a) in Figure 11, the cutting line WCL of detection sheet shaped piece F11, using cutting Disconnected device 184 cuts off sheet shaped piece F11 along cutting line WCL.The optics structure that the direction of optic axis has been controlled very closely as a result, Part FO is configured to desirable size and configuration is in desirable position.Thus, it is possible to provide display quality excellent narrow frame Optical display device DP.
