Neon lamp strip with four-side light emitting function

ActiveCN222437778UUniform luminanceuniform light distributionElectric lightingLight fasteningsEngineeringSilica gel
The neon lamp strip comprises a light-emitting assembly, a first rectangular transparent silica gel sleeve, a rectangular diffusion silica gel sleeve and a second rectangular transparent silica gel sleeve. The light-emitting assembly comprises a first FPC board and a second FPC board. A plurality of first lamp beads arrayed in the length direction of the first FPC board are arranged on the upper surface of the first FPC board, and a plurality of second lamp beads arrayed in the length direction of the second FPC board are arranged on the lower surface of the second FPC board. The first lamp beads and the second lamp beads are distributed in an up-down staggered mode. Four diffusion silica gel sheets which are distributed in a matrix are embedded in the tube wall of the first rectangular transparent silica gel sleeve; wherein two of the diffusion silica gel sheets are obliquely arranged, and the inclined surfaces of the diffusion silica gel sheets face the first lamp bead, and the other two diffusion silica gel sheets are obliquely arranged, and the inclined surfaces of the diffusion silica gel sheets face the second lamp bead. The neon lamp strip can emit light from four sides and can effectively reduce the area of a dark area, so that the neon lamp strip is uniform in brightness from four sides, and the light-emitting effect is effectively improved.

Display device

ActiveCN117475840BUniform luminanceImprove light and dark uniformityStatic indicating devicesDisplay deviceData signal
The display device provided in the application detects the pixel voltages of the first to-be-detected sub-pixel and the second to-be-detected sub-pixel electrically connected to the same data line through the detection module. The first to-be-detected sub-pixel is a sub-pixel in which the first transistor electrically connected to the data line is turned on to write the data signal, and the second to-be-detected sub-pixel is a sub-pixel in which the second transistor electrically connected to the data line is turned on to write the data signal. The pixel voltage of the first to-be-detected sub-pixel is related to the turn-on degree of the first transistor, and the pixel voltage of the second to-be-detected sub-pixel is related to the turn-on degree of the second transistor. The compensation module provides a compensation signal to the clock signal control module according to the detection result of the detection module. The voltage value of the first clock signal for controlling the turn-on of the first transistor or the voltage value of the second clock signal for controlling the turn-on of the second transistor is compensated by the clock signal control module, so that the luminance of the sub-pixels on the same data line is consistent, and the brightness and darkness uniformity of the display picture is improved.

Horse race luminous efficiency light guide plate and preparation method thereof

The invention relates to the technical field of light guide elements, in particular to a horse race lighting effect light guide plate which comprises an injection molding light guide plate, a reflecting film covering and attached to the bottom face of the injection molding light guide plate and a shading film partially covering and attached to the top face of the injection molding light guide plate. The area, located between the periphery of the injection molding light guide plate and the periphery of the shading film, of the injection molding light guide plate is a light emitting area, the outer side face of the injection molding light guide plate is obliquely arranged towards the center direction of the injection molding light guide plate from bottom to top, and the outer side face of the injection molding light guide plate and the top face of the injection molding light guide plate are arranged in a fillet mode. Light is smoothly transited to the corner between the outer side face of the injection molding light guide plate and the bottom face of the injection molding light guide plate and then is dispersed through the reflecting film, so that the phenomenon that a local area of a light emitting area is exploded and brightened due to the fact that a horse race luminous efficiency light source is too close to the light emitting area is effectively improved, the light emitting brightness of the light emitting area is balanced, and the light emitting effect is improved.

Reflecting lampshade and backlight module

The utility model relates to a reflection lampshade and a backlight module, the reflection lampshade comprises a reflection lampshade, a plurality of first lamp cups and a plurality of second lamp cups, and more light can enter the periphery of the reflection lampshade through third reflection holes. The light entering the second reflection hole and the first reflection hole can be reflected to the periphery of the reflection lampshade through the second lamp cup and the first lamp cup, the first lamp cup with the higher vertical height is good in light condensation effect, the light diffusion direction is more accurate, and the service life of the lamp is prolonged. The second lamp cup with the lower vertical height can enable light to be diffused to the periphery of the reflection lampshade more widely, so that more light is diffused to the periphery of the reflection lampshade, the brightness of the periphery of the reflection lampshade is improved, the situation that some areas on the reflection lampshade are too bright and the periphery is too dark is avoided, and therefore the overall luminance of the backlight module is uniform, and the backlight module is more attractive. And the display effect of the backlight module is improved.

ActiveCN114967225BIn line with the design trend of thin and lightUniform luminanceNon-linear opticsIdentification meansDisplay deviceEngineering
The present invention discloses a display, which includes a back plate, a cover plate, a light-transmitting plate and a light-emitting mechanism. The back plate and the light-transmitting plate form a storage cavity. The cover plate is arranged on the side of the back plate away from the light-transmitting plate. The cover plate and the back plate cooperate to form a storage space. The storage cavity and the storage space are arranged along the extension direction of the light-transmitting plate. The light-transmitting plate includes a coating layer and a transparent substrate layer that are stacked. The light-emitting mechanism is installed on the back plate, and the light emitted by the light-emitting mechanism is incident on the light-transmitting plate. Since the cover plate and the back plate form a storage space, and the storage space and the storage cavity are arranged along the extension direction of the light-transmitting plate, the electronic components of the display can be placed in the storage space, so the thickness of the display will not be increased. The light-transmitting plate composed of the coating layer and the transparent substrate layer is used, so that the light emitted by the light-emitting mechanism is incident on the light-transmitting plate, and the light can propagate in the transparent substrate layer, and then diffused by the coating layer, so that the display has uniform luminous brightness.
