Display with wide viewing area

The present invention provides a display, and more particularly a display having a wide viewing area without reducing the size of the frame.

The appearance of display devices (such as computer screens and mobile screens) with ultra-thin bezels is one of the factors that increase consumer desire to buy. The greater the ratio of the displayed image to the surface area of the display device, the smaller the ratio of the border to the surface area of the display device. Although the display of the ultra-thin bezel has better market competitiveness, the display area of the display device is equivalent to the size of the optical components (such as polarizers) of the display module, and the size of the frame depends on the structural design, product assembly and safety. Factors such as strength are difficult to narrow and narrow indefinitely. Therefore, how to overcome the size limitation of the frame and design a display device with a narrower border or no border is an important development goal of the relevant institution industry.

The present invention provides a display having a wide viewing area without reducing the size of the frame to solve the above problems.

The patent application scope of the present invention discloses a display having a wide viewing area, which comprises a frame body, a display module and a panel module. The display module is disposed in the frame, and the panel module is disposed on the frame and covers the display module. The panel module has a visible area overlapping the display module. The panel module comprises a light transmissive glass, a carrier film and a microlens combination. The carrier film is disposed between the light transmissive glass and the display module. The microlens combination is located at the In the visible area, and disposed between the display module and the transparent glass. The microlens assembly has optical properties of divergent light.

The display of the present invention does not need to change the size of the frame, but uses a combination of microlenses disposed between the display module and the light transmissive glass to refract light, thereby magnifying the image output by the display module to a range of the visible area, providing a narrow The visual effect of the border. The microlens assembly may be disposed on the carrier film or the light transmissive glass, and may include a plurality of plano-convex lens units or plano-concave lens units according to the position of the lens and the change in the orientation of the lens unit. The purpose of the microlens assembly is to converge the image light from the display module, thereby diverging the image light to emit it through the light transmissive glass, so that the panel module can have the visual effect of enlarging the image of the display area to the size of the visible area.

The microlens assembly is composed of a transparent material, such as indium tin oxide (ITO) or other transparent material, which is directly formed or bonded to the carrier film or the light transmissive glass by printing, imprinting or etching, so the microlens is used. Combining to produce an enlarged image does not increase the assembly steps of the display. Compared with the prior art, the display of the present invention has the advantages of compact size and easy assembly, can form a wide viewing area and cause a visual effect of a narrow bezel, and does not need to physically narrow the frame size to damage the structural strength of the display.

The display area Rd is divided into a main display area R1 and a sub display area R2. The sub-display area R2 may have a frame shape and is disposed around the periphery of the main display area R1, that is, the position of the sub-display area R2 is between the main display area R1 and the frame 12. The microlens assembly 24 is preferably disposed in the sub display region R2 for refracting light passing through the boundary of the display region Rd (for example, the sub display region R2) to display the display region Rd. The image is enlarged to the extent of the visible area Rv. However, the arrangement area of the microlens assembly 24 is not limited to the foregoing embodiment, and for example, a part of the microlens assembly 24 can also be disposed in the main display area R1. Any technique that can refract light through a combination of microlenses to magnify an image belongs to the design of the present invention, and therefore, other embodiments will not be separately illustrated.

Referring to FIG. 5, FIG. 5 is a cross-sectional view showing a portion of a panel module 16C according to a third embodiment of the present invention. The circuit assembly 32 of the panel module 16C also has a carrier film 34 and a control circuit 36. The control circuit 36 can be disposed on one or both sides of the carrier film 34, and the circuit assembly 32 is located on the transparent glass 20 and the display module. 14 rooms. The carrier film 22 of the third embodiment is separated from the line assembly 32 is a separate component located between the light transmissive glass 20 and the line assembly 32. The microlens assembly 24 is disposed on the upper end surface of the carrier film 22, and the lower end surface of the carrier film 22 is adhered to the line assembly 32. The carrier film 22 of the third embodiment is adhered to the side of the line assembly 32 facing the light transmissive glass 20, so the microlens assembly 24 includes a plurality of plano-convex lens units 38 positioned between the carrier film 22 and the light transmissive glass 20. The convex surface of any of the plano-convex lens units 38 faces the light transmissive glass 20.

Please refer to FIG. 6. FIG. 6 is a cross-sectional view showing a part of the panel module 16D according to the fourth embodiment of the present invention. The circuit assembly 32 of the panel module 16D has a carrier film 34 and a control circuit 36 that can be disposed on one or both sides of the carrier film 34. In particular, the microlens assembly 24 of the fourth embodiment is disposed on a side of the light transmissive glass 20 facing the display module 14, and the carrier film 22 is located between the microlens assembly 24 and the line assembly 32. Therefore, the microlens assembly 24 includes a plurality of plano-concave lens units 30, and the concave surface of either of the plano-concave lens units 30 faces the carrier film 22. The carrier film 22 can be used to prevent the microlens assembly 24 from directly touching the line assembly 32 when the light transmissive glass 20 is pressurized.
