For the curved surface display module in the prior art, because the top surface of the reflection cavity support is a curved surface and the patch light emitting devices are all arranged on the hard circuit board with the flat structure, in order to ensure the display uniformity among different pattern parts, additional compensation measures need to be made, for example, when the distance between the pattern parts and the corresponding patch light emitting devices is too small, resistors need to be connected in series on the patch light emitting devices to weaken the brightness of the patch light emitting devices; or the distance between the pattern part and the corresponding patch light emitting device is too large, more patch light emitting devices need to be arranged to enhance the light emission of the pattern part. In practical operation, the above compensation measures are all insufficient, such as the former compensation measure may cause color difference in display of the pattern portion while reducing the brightness of the patch light emitting device, and the latter compensation measure has a plurality of light emitting devices arranged in one reflective cavity, so that the brightness often cannot reach the required brightness, and meanwhile, the phenomenon of light and shadow superposition of the corresponding pattern portion may occur.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The first embodiment is as follows:
FIG. 2 is a schematic diagram of a curved display module according to an embodiment of the invention. The embodiment of the invention provides a curved surface display module which comprises a reflecting cavity support 1, a pattern film 2 and a plurality of light-emitting devices 4.
Specifically, the top surface of the reflection cavity support 1 is a curved surface, the pattern film 2 is attached to the top surface of the reflection cavity support 1, and correspondingly, the final shaping structure of the pattern film 2 is a curved surface pattern film.
The reflector holder 1 has a number of reflector cavities 3 arranged on the top surface of the reflector holder 1.
Optionally, the top surface of the reflection cavity bracket 1 is provided with a plurality of groups of cup structures in the areas corresponding to the plurality of reflection cavities 3; any reflection cavity 3 in the plurality of emission cavities 3 is formed by surrounding a corresponding group of cup structures in the plurality of groups of cup structures.
It should be noted that the reflective cavity 3 refers to a cavity structure, and basically, the reflective cavity 3 is used for accommodating the light emitting device 4, and light of the light emitting device 4 is transmitted out of the reflective cavity 3 onto the pattern film 2, and therefore, the reflective cavity 3 must be opened in a direction corresponding to one side of the pattern film 2, that is, the reflective cavity 2 is in contact with the pattern film 2 in a direction corresponding to one side of the pattern film 2. Basically, the cup structure is a technical means for forming the reflective cavity 3, and the specific structure of the cup structure will be described in the following embodiments.
Specifically, the pattern film 2 is provided with a plurality of pattern portions (fig. 2 is not marked for the reason of viewing angle, and is understood by combining the following characters and the description of the following embodiments); the pattern portion is a region for displaying a pattern on the pattern film 2, generally, the region of the pattern film 2 except the pattern portion is opaque, and the pattern portion is processed into a hollow structure or a light-transmitting structure according to a process for transmitting light. In a specific implementation, any one of the reflective cavities 3 corresponds to a position where one of the plurality of pattern portions is disposed, and each pattern portion is controlled and displayed by a light emitting device in one of the reflective cavities 3.
It should be noted that, a pattern portion according to the embodiment of the present invention does not refer to a pattern, but refers to a pattern in one area, and it is specifically understood that a pattern in an area corresponding to one reflective cavity 3 is a pattern portion.
Specifically, the plurality of light emitting devices 4 are respectively arranged in the plurality of reflective cavities 3, and the number of the light emitting devices 4 in any one reflective cavity 3 of the plurality of reflective cavities 3 is at least one; any one of the plurality of light emitting devices 4 includes a light emitting portion, and a distance between any one of the plurality of light emitting devices 4 and the corresponding pattern portion is equal. In the embodiment of the present invention, the position area where the light emitting device 4 actually emits light is named as a light emitting part (distinguished from the structure of the pin, the bracket, etc.), and the display effect of the pattern part is affected by the distance between the corresponding light emitting part and the pattern part, so that, in order to make the final display effect of each pattern part tend to be uniform, the distance between the light emitting part and the corresponding pattern part of the light emitting device of the embodiment of the present invention is equal (marked by the distance L in the present embodiment), thereby ensuring that the display uniformity of each pattern part tends to be uniform. Specifically, the following embodiments will explain the specific arrangement structure of the light emitting device.
In addition, regarding the concept that the distance between the light emitting part and the pattern part is equal, on one hand, in practical implementation, the light emitting part is a space region, the pattern part is a curved surface region, and the distance between the light emitting part and the pattern part is difficult to define, and generally, the distance between the light emitting part and the pattern part can be specifically understood as the distance from one point on the light emitting part (such as the center point of the light emitting part) to one point on the pattern part (such as the center point of the pattern part); on the other hand, since there is no absolute equality in actual manufacturing, the equality of the distances between the light emitting portion and the pattern portion is equal to a theoretical value, and the actually produced product may have a certain dimensional error. In summary, in terms of the definition that the defined distance between the light emitting part and the pattern part is equal, there may be a certain dimension error in the distance between the light emitting part and the pattern part for the actual product, but the related product should be included in the technical content and the technical features disclosed in the embodiments of the present invention.
In summary, the embodiment of the present invention provides a curved display module, which is different from the arrangement form of the circuit board in which the light emitting devices are all arranged in a unified flat plate structure in the prior art, and the distance between the light emitting device and the corresponding pattern portion in each reflective cavity is adjusted in a targeted manner, so that the uniformity of the display effect among different pattern portions tends to be consistent.
