[0003] There are multiple LED lights under the display panel of the vacuum cleaner working at the same time. Because the distance between the LED lights and the display panel is relatively close, there will be shadow areas (partially relatively dim) on the display panel. Because these shadow areas are far away from the LED light source, there is only a small amount of light. Irradiate these areas, resulting in poor display effect of the display panel
When eliminating light shadows in existing vacuum cleaners, one is to increase the distance between the LED light source and the display panel, which will also increase the irradiation range of the light source, thereby covering the shadow area, but will increase the thickness of the vacuum cleaner; That is, the number of LED lights) will lead to an increase in cost

Abstract
The dust collector display panel comprises a PCB, a light guide plate, a light-transmitting film and a panel, the PCB is provided with a plurality of light source parts which are arranged at equal intervals in the length direction of the PCB, and the surface of the side, facing the light source parts, of the light guide plate is provided with a plurality of concave first arc surfaces which are arranged at equal intervals in the length direction of the PCB; one first arc surface corresponds to one light source part in position, the light-transmitting film is fixedly mounted on the light guide plate, and the panel is fixedly mounted on the light-transmitting film. Compared with the prior art, on the basis that the thickness of the dust collector is not changed, the shadow area on the display panel is effectively eliminated, and meanwhile the cost is effectively controlled.
Description
technical field [0001] The invention belongs to the field of vacuum cleaner display panels, and in particular relates to a vacuum cleaner display panel for eliminating light and shadow. Background technique [0002] A vacuum cleaner is a cleaning device widely used in human life and industrial production. The working principle of the vacuum cleaner is to use the motor to drive the blades to rotate at a high speed, generate negative air pressure in the sealed shell, and then absorb the dust through the external vacuum pipe. [0003] There are multiple LED lights under the display panel of the vacuum cleaner working at the same time. Due to the close distance between the LED lights and the display panel, there will be shadow areas on the display panel (partially dim), because these shadow areas are far away from the LED light source and have only a small amount of light. These areas are irradiated, resulting in poor display effect of the display panel. When eliminating light...
