The display device includes a display panel including an active area and a non-active area; and a polarization plate on the display panel, the polarization plate including a polarization layer. The polarization layer includes a first pattern corresponding to the active area and a second pattern corresponding to the non-active area, and the second pattern is spaced apart from the first pattern. Thus, it is possible to delay moisture absorption of a polarization layer.

The back plate assembly contains a back plate and a reinforcing plate fixed to a back side of the back plate. The reinforcing plate has a hollowed out pattern with a number of connected reinforcing ribs. A backlight module and a display device incorporating the back plate assembly are also disclosed. The reinforcing plate is designed and manufactured separately and then fixed to the back plate. The reinforcing ribs and engraved openings are integrated on the reinforcing plate, achieving superior capability to withstand deformation and flexibility in customization to suit the need and appearance of various backlight modules and display devices.

A driver mounting apparatus 40 includes a driver mount-side heat supply support member 42, a substrate support member 41, a driver-side heat supply support member 43, a first moving portion 44, and a second moving portion 45. The driver mount-side heat supply support member 42 supports a driver mount portion GSd and supplies heat to the driver mount portion GSd. The substrate support member supports a substrate main portion GSm. The driver-side heat supply support member 43 supports and sandwich a driver 21 with the driver mount-side heat supply support member 42 and supplies heat to the driver 21. The first moving portion 44 relatively moves the driver mount portion GSd and the driver mount-side heat supply support member 42 in an overlapping direction in which the glass substrate GS and the driver 21 are overlapped. The second moving portion 45 relatively moves the driver 21 and the driver-side heat supply support member 43 in the overlapping direction.

A display device of the disclosure includes: a display panel; a decorative member that holds the display panel; and a light guide plate that has rigidity and includes an edge surface attached to the decorative member.

The present invention discloses a touch control device, which is addressed to the rimple problem resulting from the full-lamination design of the touch control panel and the liquid crystal display module. The present invention compensates for the elevation drop of the slightly lower control circuit region of the liquid crystal display module in a thickness-increasing way to make the entire liquid crystal display module have an identical elevation. In some embodiments, the present invention increases the thickness of a portion of a ground tape or an optical adhesion layer to compensate for the elevation drop of the liquid crystal display module with respect to the touch control panel. Thereby, the rimple problem is effectively solved.

Provided is an optical sensor mounting structure which is used in an image display device and in which the gap between a reflection sheet and a tubular cushion for preventing the entry of external light into an optical sensor is eliminated so that the amount of light from a backlight can be measured accurately. A liquid crystal image display device includes an optical sensor that measures light from the back surface of a reflection sheet, a substrate having the optical sensor thereon, and a tubular cushion for preventing the entry of external light into the optical sensor. The front surface of the tubular cushion is bonded to the reflection sheet, and the back surface thereof is bonded to the substrate.

Provided are an optical sheet holding structure capable of preventing an optical sheet from wrinkling and bending in a display apparatus, and from breakage during a vibration test, thereby preventing occurrence of problems such as uneven luminance, luminance degradation and the like, and a display apparatus including the optical sheet holding structure. A chassis for holding an optical sheet includes an engaging part for engaging the optical sheet. The engaging part includes a base provided to stand on a surface of a holding plate for the optical sheet orthogonally to the holding plate and in the thickness direction of the holding plate, and an engaging portion extending substantially parallel to a holding surface from the front edge of the base toward the outside of the frame of the chassis. A distance between the holding surface of the holding plate for the optical sheet and the surface of the engaging piece facing the holding surface is substantially equal to the thickness of the optical sheet. The cross-section of the base of a central engaging part is formed into a shape substantially identical to the shape of an engagement hole provided in the optical sheet.

A lighting device includes a light source, a substrate and a reflective sheet. The light source is mounted on the substrate. The substrate includes a substrate side opening in a vicinity of the light source. The reflective sheet is provided to cover a surface of the substrate. The reflective sheet includes a reflective sheet side opening at a location corresponding to the light source. The substrate side opening is arranged such that an inner edge portion of the reflective sheet side opening is inserted thereto or the light source is fixed thereto.

A lighting device includes a substrate, a light source and a reflective sheet. The light source is fixed relative to a surface of the substrate with a gap therebetween. The reflective sheet includes first and second portions that are separated with respect to each other and are arranged with respect to each other in a first direction. The reflective sheet is configured such that both the first and second portions are inserted into the gap between the light source and the surface of the substrate as viewed from a perpendicular direction, or such that one of the first and second portions extends through the gap between the light source and the surface of the substrate to a vicinity of the other one of the first and second portions that is provided outside of the light source as viewed from the perpendicular direction.

Provided are a backlight module, a preparation method thereof, and a display device. The backlight module includes a substrate, multiple light-emitting elements, a reflection structure and a rubber frame structure, and the multiple light-emitting elements, the reflection structure and the rubber frame structure are located on one side of the substrate. The multiple light-emitting elements and the reflection structure are located within a limited area of the rubber frame structure, and the reflection structure is located between every two adjacent light-emitting elements; and the reflection structure includes a first reflection surface adjacent to a light-emitting element, and the rubber frame structure includes a second reflection surface adjacent to the light-emitting element.
