Description

Liquid crystal display

The present invention relates to a liquid crystal display device.

In general, a liquid crystal display (LCD) has a structure in which love is injected between two glass plates, that is, an LCD panel. Thus, when electrical pressure is applied between the liquid crystals, the arrangement of each liquid crystal molecule causes a change, and various characters or images are displayed on the LCD panel according to the change of the optical refractive index. These LCDs usually operate from 1.5V to 2V power supplies and consume very little power and are widely used in mobile phones, PDAs, MP3s, computer monitors, and televisions.

On the other hand, the LCD Window (LCD Window) refers to a transparent protective window that is mounted on the outer surface of the LCD panel to protect the LCD panel from external shock, mainly acrylic (acryl), PC (Poly carbonate) or PET (Polyethylene terephthalate) It is made of a synthetic resin substrate such as).

Recently, with the development of the digital industry, various digital electronic devices are becoming smaller and slim, and the thickness of the LCD panel and the LCD window is also becoming thinner.

In this trend, the conventional LCD window has a problem that scratches easily occur on the surface by external impact or contact with the synthetic resin substrate.

The present invention provides a liquid crystal display device including a window in which scratching does not occur due to external impact or contact.

According to an aspect of the present invention, there is provided a liquid crystal display device including a liquid crystal panel and a window disposed on the liquid crystal panel and formed by mixing glass fibers with a synthetic resin material.

In the embodiment of the present invention by forming a window by mixing the glass fiber in the synthetic resin material, the strength and hardness of the window is increased, there is an effect that can prevent scratches applied to the window from the external impact.

For example, without departing from the scope of the present invention, the second component may be referred to as the first component, and similarly, the first component may also be referred to as the second component.

When a component is said to be "connected" or "connected" to another component, it may be directly connected to or connected to that other component, but it may be understood that another component may exist in between. Should be. On the other hand, when a component is said to be "directly connected" or "directly connected" to another component, it should be understood that there is no other component in between.

The terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting of the invention. Singular expressions include plural expressions unless the context clearly indicates otherwise. In the present application, the terms "comprises", "having", and the like are used to specify that a feature, a number, a step, an operation, an element, a component, But do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, or combinations thereof.

Now, a liquid crystal display according to an exemplary embodiment of the present invention will be described in detail with reference to the drawings. The same or corresponding elements are denoted by the same reference numerals regardless of reference numerals, and redundant description thereof will be omitted.

1 is an exploded perspective view of a liquid crystal display according to an exemplary embodiment of the present invention, FIG. 2 is an assembly view of FIG. 1, FIG. 3 is a cross-sectional view taken along AA of FIG. 2, and FIG. 4 is an embodiment of the present invention. A plan view of the window according.

1 to 3, the liquid crystal display device includes a liquid crystal panel 10, a backlight unit 20, a window 30, a mold frame 40, a poron tape 50, and a black pattern 60. Include.

The liquid crystal panel 10 is arranged on the top surface of the backlight unit 20 and is accommodated in the mold frame 40.

The liquid crystal panel 10 is a panel in which a liquid crystal layer is formed between the upper and lower substrates facing each other, and the liquid crystal cells are arranged in a matrix form at the intersections of the plurality of gate lines and the data lines.

The backlight unit 20 is accommodated in the mold frame 30 to generate light and emit upward.

The backlight unit 20 includes a reflective sheet 21, a light guide plate 22, a light emitting diode 23, and an optical sheet 24.

The reflective sheet 21 reflects light generated from the light emitting diode 23 upwards.

The light guide plate 22 is disposed on the upper surface of the reflective sheet 21 and receives light emitted from the light emitting diode 23 to emit light upward through reflection, refraction, and scattering.

The light emitting diodes 23 are disposed on the side surfaces of the light guide plate 22 to generate light and emit light toward the side surfaces of the light guide plate 22.

The optical sheet 24 is disposed on the upper surface of the light guide plate 22 to improve characteristics of light passing through the optical sheet 21.

The mold frame 40 accommodates the liquid crystal panel 10 and the backlight unit 20 and is made of a synthetic resin material such as polycarbonate.

The top edge of the liquid crystal panel 10 is attached to the PORON tape 50 having a thickness of about 0.4 to 0.9 mm, and a black pattern having the same size as the PORON tape 50 on the top surface of the PORON tape 50. 60 is attached. Openings 51 and 61 are formed in the porous tape 50 and the black pattern 60 so that the liquid crystal panel 10 can be seen from the outside through the window 30.

The PORON tape 50 may be attached to the upper portion of the liquid crystal panel 10 to prevent foreign substances from flowing into the liquid crystal panel 10 and may perform a predetermined insulation function.

The black pattern 60 may be attached to the upper portion of the liquid crystal panel 10 to prevent external light from flowing into the liquid crystal panel 10.
