The invention relates to a lighting device and a display device. The lighting device includes light source units (20) each having a light guide plate and at least one light source. On the light guideplate, there are arranged next to each other a lighting region (4) for causing light entered from the light source to exit to the outside and a light guide region (3) for guiding to the lighting region (4) light entered from the light source. Light source units (20) adjacent to each other in the direction of the optical axis of the light source are arranged such that the lighting region (4) of onelight source unit (20) overlaps at least a part of the light guide region (3) of the other light source unit (20). Between the light guide plate (LG(k)) of the one light source unit (20) and the light source (BL(k+1)) of the other light source unit (20), there are arranged a diffusion reflection sheet (33), and a regular reflection sheet (32) or a light absorption sheet so as to be superposed oneach other. In the tandem type lighting device where the light guide plates are overlapped each other, irregular lighting is suppressed and luminance uniformity and color mixture properties are improved.

A backlight device (2) provided with: a light-source unit (3) comprising a plurality of light-emitting diodes (9) and lenses (10) that spread the light from said light-emitting diodes (9); a housing (4) that contains said light-source unit (3); a diffusion panel (5) disposed so as to cover an opening (6a) in said housing (4); and a reflective sheet (6) that reflects light from the light-source unit (3) towards the diffusion panel (5). The light-emitting diodes (9) are arranged in one or more rows in the middle of the light-source unit (3). The lenses (10) in the light-source unit (3) have input surfaces (11) onto which the light from the light-emitting diodes (9) is incident and output surfaces (12) from which the incident light, having been spread out, is transmitted. The shape of the projection of each input surface (11) from the top surface is made elliptical about the optical axis (Z) by means of a continuous concave surface.

Provided is a display device. The device includes a plurality of point luminophors, a fogging surface body and a lens array. A certain separation distance exists between every two adjacent point luminophors, and the fogging surface body is arranged on the light emitting sides of the point luminophors. The lens array is arranged on one side of the fogging surface body and provided with multiple lens units with positive diopters. Through the match of a light diffusing component and the lens array, after light rays emitted by the luminous point luminophors penetrate through the lens array and the light diffusing component, an image, which is excellent in quality and can be watched from a short distance, can be formed, and the sufficient image luminance and visual range can be maintained at the same time.

The lenses (10) in the light-source unit (3) have input surfaces (11) onto which the light from the light-emitting diodes (9) is incident and output surfaces (12) from which the incident light, having been spread out, is transmitted. The length (d1) of the short sides of each lens (10), orthogonal to the direction in which the lenses (10) are arranged, is greater than half the minimum spacing (d3) between the lenses (10).

Provided is a driving method for a plasma display panel, and a plasma display device, wherein maintaining picture quality, improving driving margin, and reducing power consumption can be achieved, even when applied to an ultra high-definition panel. The driving method for a plasma display panel divides multiple displaying-electrode pairs into multiple displaying-electrode pair groups; divides a field period using multiple subfields, which have writing periods within which write-processing that makes writing-discharges be generated on the discharge-cells that are to emit light, and maintaining periods within which first and second maintaining pulses are provided to scanning electrodes and maintaining electrodes, so as not to have the writing periods for each of the displaying-electrode pair groups overlap, for each of the displaying-electrode pair groups. The aforementioned subfields have the periods of the first and second maintaining pulses to be longer than 5.5 [mu]s, within a range in which the period of time of the maintaining period does not exceed Tw*(N-1) / N, wherein the number of all the displaying-electrode pair groups is assumed to be N, and the time necessary for performing write-processing to the discharge-cells that correspond to all the displaying-electrode pairs is assumed to be Tw.

In a multi-scan device and method for a plasma display panel, data signals relative to each line of a frame are compared. Where two or more lines are found to be identical, only one copy of the line data is stored, together with data identifying the identical lines. Data signals having the same line data are then simultaneously scanned using the stored line data. By simultaneously scanning those lines having the same data signals, the panel scanning time is decreased. This allows the sustain time for generating light to be increased, thereby allowing a brighter image to be displayed.

A mobile phone 100 includes a plurality of operation keys and a key lock function. If an operation is performed on any of the plurality of operation keys while the key lock function is being executed, the mobile phone 100 detects the operation, and notifies a user which of the plurality of operation keys is a predetermined operation key for stopping the execution of the key lock function.
