Abstract: The disclosure provides a displaying substrate, a manufacturing method thereof, and a display panel, and relates to the technical field of display. The displaying substrate comprises a first supporting base (1), plurality of vibrating element modules (2), and a display module (3). The display module (3) comprises display units (31), connecting units (32) and hollowed-out units (33). Each connecting unit (32) is located between two adjacent display units (31). Each hollowed-out unit (33) is located between two adjacent display units (31) except an area where the corresponding connecting unit (32) is located. The hollowed-out units (33) are provided with cavities (40) corresponding to the vibrating element modules (2). Orthographic projections of the hollowed-out units (33) on a reference plane cover orthographic projections of the vibrating element modules (2) on the reference plane. The vibrating element modules (2) and the cavities (40) form a transducer.

The backlight module includes a plurality of light control region groups in one-to-one correspondence with the plurality of light-emitting diode chips, each light control region group includes at least a first light control region and a second light control region. The light control structure includes a plurality of light control substructure groups respectively located in the plurality of light control region groups. Each light control substructure group includes at least a first light control substructure in the first light control region and a second light control substructure in the second light control region.

Abstract: This disclosure relates to a see-through display device, including: a collimated light source assembly, configured to form collimated light and control a light emitting direction; a first light extraction layer, configured to extract, in a collimated manner, the light ray transmitted inside the light guide plate through a light extraction outlet; an extinction layer and a second light extraction layer, wherein the extinction layer includes a light guide region and a light absorption region which are arranged alternately, and the second light extraction layer includes multiple light extraction inlets; a reflecting layer, arranged on a side, close to the light guide plate, of the second light extraction layer and configured to reflect the collimated light extracted from the light extraction outlet to the light guide plate; and a liquid crystal dimming layer. This disclosure further relates to a manufacturing method of the see-through display device.

Abstract: The present application relates to accessories of motor vehicle, particularly to a bracket for motor vehicle rest pedal and rest pedal. The present application aims at solving the problem that existing motor vehicle rest pedals are prone to deforming and breaking. To this end, the bracket comprises a first bracket part secured within the vehicle and a second bracket part connected to the first bracket part and used for fixing the pedal plate. The second bracket part is of L-like plate structure such that a part of the second bracket part extends under the fixed pedal plate and supports the same. The structural stiffness and rigidity of the rest pedal is strengthened by the L-like plate structure of the second bracket part of the bracket of the present application to prohibit deformation of the rest pedal due to bad road condition or emergency braking.
