Detailed Description
The technical solutions of the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which are obtained by a person skilled in the art based on the embodiments of the present application, fall within the scope of protection of the present application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more.
Referring to fig. 1 to 19, a display module is disclosed in an embodiment of the application, and the disclosed display module includes a main display 210, a sub display 220 and a driving mechanism.
The main display screen 210 includes a light transmissive region 211. The light-transmitting region 211 may be a light-transmitting through hole provided in the main display screen 210, or may be a region provided in the main display screen 210 that is not perforated and is capable of transmitting light. The main display 210 may be an OLED display.
The sub display 220 is a flexible screen, and at least part of the sub display 220 is opposite to the light-transmitting region 211. The flexible screen may be a flexible OLED display screen. Alternatively, the sub display 220 may be disposed in parallel with the main display 210.
The driving mechanism is connected to the sub-display 220, and the driving mechanism can drive the sub-display 220 to switch between the first state and the second state by using the flexible screen bendable and crimpable characteristics. Alternatively, the first state may be an expanded state and the second state may be a contracted state, a rolled state, or a collapsed state.
In the case where the sub-display 220 is in the first state, the pixel density of the region on the sub-display 220 opposite to the light-transmitting region 211 is the first density, and the light transmittance of the region on the sub-display 220 opposite to the light-transmitting region 211 is the first light transmittance. At this time, the pixel density of the area opposite to the light-transmitting area 211 on the auxiliary display screen 220 is lower, the light transmittance is higher, and the pixel density of the area corresponding to the light-transmitting area 211 of the display module is inconsistent with that of other areas, so that the area corresponding to the light-transmitting area 211 of the display module is inconsistent with that of the pictures displayed by other areas, resulting in poor display effect of the display module, but the light transmittance of the area corresponding to the light-transmitting area 211 of the display module is higher, so that enough light can pass through the display module.
In the case where the sub display 220 is in the second state, the pixel density of the region of the sub display 220 opposite to the light-transmitting region 211 is a second density, the second density is greater than the first density, and the light transmittance of the region of the sub display 220 opposite to the light-transmitting region 211 is a second light transmittance, the second light transmittance being less than the first light transmittance. At this time, the light transmittance of the area of the auxiliary display screen 220 opposite to the light-transmitting area 211 is lower and the pixel density is higher, in this case, the auxiliary display screen 220 may fill the blank or the portion with lower pixel density formed by the light-transmitting area 211 of the main display screen 210, so that the pixel density of the area of the display module corresponding to the light-transmitting area 211 is consistent with that of the other areas, and further, the area of the display module corresponding to the light-transmitting area 211 is consistent with that of the other areas, so that the display effect of the display module is better and the user experience is improved.
In the embodiment of the application, the driving mechanism can drive the auxiliary display screen to switch between the first state and the second state, and under the condition that the auxiliary display screen is switched to the first state, the pixel density of the area opposite to the light transmission area on the auxiliary display screen is lower, the light transmission rate is higher, the resolutions of different areas of the display module are inconsistent, the overall display effect of the display module is poorer, and more light rays can pass through the display module. Under the condition that the auxiliary display screen is switched to the second state, the pixel density of the area, opposite to the light transmission area, of the auxiliary display screen is higher, the light transmittance is lower, the resolution of each area of the display module is consistent, and then the overall display effect of the display module is better, but fewer light rays can pass through the display module. Therefore, the display module disclosed by the application can solve the problem of poor display effect caused by inconsistent pictures displayed in different areas of the pixels of the full-face screen. Meanwhile, the display module disclosed by the application can also ensure enough light to pass through the display module.
In the above-mentioned scheme, the auxiliary display screen 220 is driven to switch between the first state and the second state by the driving mechanism, and the driving mechanism may be various, for example, the driving mechanism may be a memory alloy driver or a screw mechanism, and the driving mechanism may also be an electromagnetic induction structural member, for example, the driving mechanism may include an electromagnetic coil and a permanent magnet, and the auxiliary display screen 220 is driven to stretch and retract by magnetic force generated by the mutual cooperation of the electromagnetic coil and the permanent magnet.
Of course, other mechanisms may be used for the drive mechanism, such as hydraulic telescoping members, pneumatic telescoping members, etc., and embodiments of the present application are not limited to the particular type of drive mechanism. In an alternative embodiment, the driving mechanism may be an electrostrictive material 400, and the electrostrictive material 400 is switched between an energized state and a de-energized state, so as to drive the secondary display 220 to switch between the first state and the second state. In this case, the expansion and contraction of the sub-display 220 are driven by the characteristic that the electrostrictive material 400 can expand when energized, so that the state of the sub-display 220 is switched.
In addition, compared with the mechanical driving mechanism such as the screw mechanism, the electrostriction material piece 400 has relatively compact structure, higher adjustment precision, smaller transmission loss and quicker response, and can realize high-precision stepless adjustment.
The electronic device further includes a circuit board 500, and the electrostrictive material 400 can be electrically connected to the circuit board 500, thereby supplying power and controlling the electrostrictive material 400. The circuit board 500 may be a flexible circuit board.
In the extension and retraction directions of the electrostrictive material 400 and the auxiliary display screen 220, one end of the auxiliary display screen 220 may be connected to the case 100, the other end of the auxiliary display screen 220 may be connected to the electrostrictive material 400, the electrostrictive material 400 drives the auxiliary display screen 220 in the process of electrically elongating the electrostrictive material 400, the auxiliary display screen 220 is unfolded and switched to the first state, and the electrostrictive material 400 compresses the auxiliary display screen 220 in the process of electrically withdrawing the electrostrictive material 400, so that the auxiliary display screen 220 is switched to the second state. However, such a connection structure makes it necessary for the electrostrictive material 400 and the sub display panel 220 to occupy a large space.
In order to solve the above-described problems, in the disclosed embodiment of the present application, the circuit board 500 may have two mounting portions 510, and the two mounting portions 510 may have a light-transmitting gap in a direction perpendicular to the extension and contraction direction of the electrostrictive material 400, the light-transmitting gap being opposite to the light-transmitting region 211, the number of the electrostrictive material 400 may be two, the two electrostrictive material 400 being one-to-one corresponding to the two mounting portions 510 and being movably disposed, and the length of the mounting portion 510 being greater than the length of the electrostrictive material 400 in an extended state. In a direction perpendicular to the extension and contraction direction of the sub display 220, portions of the sub display 220 adjacent to both side edges are respectively connected to the two electrostrictive material pieces 400. Under such a situation, the two electrostrictive material pieces 400 respectively drive the edges of the two sides of the auxiliary display screen 220 to move, so that the stress of the auxiliary display screen 220 is uniform, and further, the two sides of the auxiliary display screen 220 are synchronously unfolded and synchronously contracted, so that the deviation of the expansion direction of the auxiliary display screen 220 caused by uneven stress of the auxiliary display screen 220 is avoided, and further, unnecessary interference can be avoided.
In addition, the auxiliary display 220 and the electrostrictive material 400 of the connection structure occupy a small space as a whole, and the structure of the electronic apparatus can be made more compact in the case of mounting the display module to the electronic apparatus.
In the above-mentioned aspect, the electrostrictive material 400 may be movably disposed in the mounting portion 510, in an alternative embodiment, the mounting portion 510 may be provided with a bar-shaped groove, the electrostrictive material 400 is disposed in the bar-shaped groove, the length extension direction of the bar-shaped groove is consistent with the extension direction of the electrostrictive material 400, and the length of the bar-shaped groove is greater than or equal to the length of the electrostrictive material 400 in the extended state, so that the electrostrictive material 400 is smoothly extended.
In another alternative embodiment, the electrostrictive material 400 may be movably sleeved on the mounting portion 510, and this connection manner makes the assembly stability of the electrostrictive material 400 and the mounting portion 510 better than the manner in which the bar-shaped groove is provided.
In the embodiment of the present application, the auxiliary display screen 220 may include a light-transmitting base 221 and display pixels 222 disposed on the light-transmitting base 221, and the auxiliary display screen 220 is an elastic screen, so that the auxiliary display screen 220 may be switched between a planar structure and a bent structure, so as to implement switching of the auxiliary display screen 220 between a first state and a second state.
In particular, referring to fig. 5 to fig. 7 again, in the case where the secondary display 220 is in the first state, the secondary display 220 may have a planar structure, and the display pixels 222 are located on a surface of the planar structure facing the light-transmitting region 211, where the area of the surface of the secondary display 220 facing the light-transmitting region 211 is larger, so that the density of the display pixels 222 is smaller, the light transmittance is higher, and the pixel density of the secondary display 220 is further the first density.
Referring to fig. 2 to fig. 4 again, in the case where the secondary display 220 is in the second state, the secondary display 220 may have a bent structure, where the secondary display 220 includes a plane 220a and a bent surface 220b that are distributed in a staggered manner, and the plane 220a faces the light-transmitting region 211, and the display pixels 222 are located on a surface of the plane 220a facing the light-transmitting region 211, at this time, the area of the plane 220a is smaller, so that the density of the display pixels 222 on the plane 220a is larger, the light transmittance is lower, and then the pixel density of the secondary display 220 is the second density.
In the embodiment of the present application, the display pixels 222 are always located on the surface of the secondary display screen 220 facing the light-transmitting area 211, and the area of the surface of the secondary display screen 220 facing the light-transmitting area 211 is changed by switching the secondary display screen 220 between the planar state and the bent state, so as to change the pixel density of the secondary display screen 220.
Based on the display module of the embodiment of the application, the embodiment of the application also discloses electronic equipment. The disclosed electronic device includes a housing 100 and optical components.
The housing 100 provides a mounting base for part of the functional components of the electronic device, such as the main display screen 210 and the optical components. In the embodiment of the present application, the optical component may be the camera 300 or the optical sensor.
The main display screen 210 is disposed on the housing 100, and the main display screen 210 and the housing 100 form an equipment cavity, and the optical components and the driving mechanism are disposed in the equipment cavity, so as to realize protection of the optical components and the driving mechanism, and the light inlet region of the optical components is opposite to the light transmission region 211, so that light can penetrate through the light transmission region 211 and enter the light inlet region of the optical components, thereby realizing corresponding functions of the optical components. For example, in the case where the optical component is the camera 300, the lens of the camera 300 is opposite to the light-transmitting region 211, so that light can be incident on the lens through the light-transmitting region 211, thereby realizing the shooting function of the camera 300. Alternatively, the sub display 220 may be disposed between the light-transmitting region 211 and the optical component.
In the embodiment of the present application, the state of the secondary display screen 220 is switched according to the working state of the optical component, and when the optical component is in the working state, the driving mechanism drives the secondary display screen 220 to switch to the first state, so that the light transmittance of the region of the secondary display screen 220 opposite to the light transmission region 211 is higher, thereby ensuring that enough light can be injected into the optical component, and further ensuring that the optical component can better realize the corresponding function; under the condition that the optical components are in a non-working state, the driving mechanism drives the auxiliary display screen 220 to be switched to a second state, so that the pixel density of the auxiliary display screen 220 is higher, the display pictures of all areas of the display module are consistent, the overall display effect of the display module is better, and the use experience of a user is improved.
In the above-mentioned scheme, at least part of the secondary display screen 220 is opposite to the light-transmitting area 211, the light-entering area of the optical component is opposite to the light-transmitting area 211, and the light is sequentially emitted into the light-entering area of the optical component through the light-transmitting area 211 and the secondary display screen 220, that is, the area of the secondary display screen 220 opposite to the light-transmitting area 211 is located between the primary display screen 210 and the optical component, so as to avoid the secondary display screen 220 touching the primary display screen 210 or the optical component in the switching process between the first state and the second state, resulting in friction or collision loss, and in the light-entering direction of the optical component, there is a safe space between the primary display screen 210 and the optical component and the secondary display screen 220.
In order to ensure the assembly stability of the secondary display 220, the electronic device may further include a support structure, and the secondary display 220 may be supported by the housing 100 or the primary display 210 through the support structure, thereby ensuring the assembly stability and the position stability of the secondary display 220.
In an alternative, the housing 100 may include a bottom case 110, the bottom case 110 may be disposed opposite to the main display 210, and the optical components may be fixedly disposed on the bottom case 110. Alternatively, the optical components may be fixedly disposed on the bottom case 110 through a connection member such as a screw. The electronic device may further include two support bases 610, in the telescopic direction of the secondary display screen 220, the two support bases 610 may be respectively connected to two ends of the secondary display screen 220, ends of the two support bases 610, which are far away from the secondary display screen 220, may be both movably connected to the bottom case 110, and in the process of switching the secondary display screen 220 between the first state and the second state, the two support bases 610 may relatively move with respect to the bottom case 110 in the telescopic direction of the secondary display screen 220.
