Description

Technical Field

[0001] The utility model relates to the technical field of display equipment, in particular to a reflective display with an embedded auxiliary desk lamp. Background Art

[0002] Current state of conventional technology Recently, awareness of eye protection and environmental protection and power saving has risen, and the application and demand of reflective displays have become more and more popular. The display principle of reflective displays mainly relies on ambient light to provide incident light source to help the display reflective display. Generally speaking, the stronger the ambient light, the clearer the image of the reflective display will be. However, some scene limitations with insufficient illumination of ambient light sources are often the biggest application problem of this type of display. For this reason, auxiliary light sources are needed to help reflective displays for effective display and application.

[0003] In the prior art, the method of adding a front light module is currently a reflective display, which is a common auxiliary light source. The so-called front light module refers to an auxiliary lighting application of a light guide plate combined with LED side light, which can provide a uniform light source to guide the display surface and then reflect the display to help. The front light module is often used in an environment with insufficient light. The main disadvantage is that it is expensive. As the size of the display increases, the uniformity of the light guide will become more difficult to control, so it is not suitable for large-size product applications.

[0004] The existing technology uses external or external auxiliary light sources, which are cheap, but there are application problems, mainly because the operating space is expanded and because the light source and the reflective display do not have a fixed optical spatial relationship. If the best reflection effect is required, external conditions need to be fixed and the matching relationship between the two needs to be maintained, which is relatively limited in use. Due to the differences in the characteristics of different reflective display technologies, the requirements for the incident light angle and other characteristics of the auxiliary light source are different. For example, the reflective liquid crystal display (Reflective LCD, RLCD) technology has the characteristics of fast update speed, but the incident light angle of the auxiliary light source is more restricted. Relatively speaking, the electrophoretic display (Electrophoretic display, EPD) technology has the characteristics of high reflectivity and has less restrictions on the incident light angle of the auxiliary light source. The above two auxiliary light source technologies are difficult to fully support all reflective display technologies to have good reflective display results. Summary of the invention

[0005] The purpose of the utility model is to provide a reflective display with a built-in auxiliary desk lamp, which provides an auxiliary light source to help the reflective display to display effectively in scenes with insufficient ambient light illumination, while meeting the requirements of different reflective display technology characteristics, taking into account ease of use, display effect and cost assistance.

[0051] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application.

[0052] As Figure 1 to Figure 1 shown in one of Figures 1, the present invention discloses a reflective display with an embedded auxiliary desk lamp, which includes:

[0059] Furthermore, the power module performs step-up / step-down / voltage stabilization processing and AC / DC conversion on the input power supply.

[0060] Furthermore, it includes a mechanism support base 5, used to support all modules or units.

[0061] Furthermore, the mechanism support base 5 has a support body and more than three support feet provided at the bottom of the support body. The upper end of the support body is detachably and fixedly installed with the mechanism cover plate 4.

[0062] Furthermore, the mechanism cover plate 4 wraps around the four sides of the reflective display module 1 to form four borders of the mechanism cover plate 4.

[0063] Furthermore, the auxiliary lighting unit 2 and the speaker unit 3 are installed on the borders of the mechanism cover plate 4. Specifically, the auxiliary lighting unit 2 and the speaker unit 3 are located on the front side of the border to face the user.

[0064] Furthermore, one end of the auxiliary lighting unit 2 is installed on the border of the mechanism cover plate 4 through a rotating shaft.

[0065] Furthermore, there are more than two auxiliary lighting units 2. The auxiliary lighting units 2 are divided into a horizontal auxiliary lighting unit 21 and a vertical auxiliary lighting unit 22; the vertical auxiliary lighting unit 22 is installed on at least one of the left and right side borders of the mechanism cover plate 4; the horizontal auxiliary lighting unit 21 is installed on the upper border of the mechanism cover plate 4.

[0066] Furthermore, each horizontal auxiliary lighting unit 21 includes a plurality of electrically connected LED lamp beads 6 in series to meet the incident light requirements for the bottom lighting of the reflective display screen; the horizontal auxiliary lighting unit 21 is installed on the border of the mechanism cover plate 4 through a rotating shaft so as to rotate and adjust the lighting range of the horizontal auxiliary lighting unit 21 to increase the lighting coverage range of the reflective display screen. The allowable range of the rotation angle θ of each horizontal auxiliary lighting unit 21 satisfies: 0 degree ≤ θ ≤ 90 degrees.

[0067] Furthermore, the LED series length lH of each horizontal auxiliary lighting unit 21 satisfies: 1 / 4 of the horizontal display width X of the effective reflective display area ≤ lH ≤ 1 / 2 of the horizontal display width X of the effective reflective display area.

[0068] Further, each vertical auxiliary lighting unit 22 includes a plurality of LED lamp beads 6 to meet the incident light requirements of side lighting for the reflective display screen; the vertical auxiliary lighting unit 22 is installed on the frame of the mechanism cover plate 4 through a rotating shaft 7 so as to rotate and adjust the lighting range of the vertical auxiliary lighting unit 22 to increase the lighting coverage range of the reflective display screen.

[0070] Further, the plurality of LED lamp beads 6 of each auxiliary lighting unit 2 are electrically connected in series in a fixed or unequal spacing.

[0071] Further, the spacing of the unequal spacing electrical series connection is 1 mm to 30 mm; the total number of LED light-emitting lamp beads is determined according to different lighting brightness and power consumption specification requirements.

[0072] Further, when the LED light-emitting lamp beads adopt an unequal spacing design, the LED light-emitting lamp beads near the rotating shaft 7 adopt a sparse spacing design, and the LED light-emitting lamp beads far from the rotating shaft 7 adopt a dense spacing design.

[0076] Further, the surface of the reflective display module 1 is provided with an anti-glare film layer, or a low-reflection film layer, or an anti-glare film layer and a low-reflection film layer.

[0077] Specifically, the reflective display module 1 adopts a surface processing or an external film material method to make the surface of the reflective display screen have surface characteristic functions such as AG (Anti-Glare) anti-glare and LR (Low-Reflection) low reflection. The function of AG anti-glare is to make the external incident light enter the surface of the reflective screen, generate diffuse reflection, reduce glare, and reduce the interference of seeing the LED lamp shadow mapping. The function of the LR low-reflection surface treatment is to make the external incident light enter the surface of the reflective screen, suppress the surface reflection interference, and help the reflective screen improve the contrast and color correctness.

[0078] The specific principle of the present utility model will be described in detail as follows:

[0079] Embodiment (1): As Figure 3 or Figure 4 shown. One or more auxiliary lighting units can be divided into horizontal or vertical designs. On the top side of the reflective display screen, one or more horizontal auxiliary lighting units are configured. Each horizontal auxiliary lighting unit is composed of a plurality of LED lamp beads 6 connected in electrical series to meet the incident light requirements for bottom lighting of the reflective display screen, and the lighting range of the horizontal auxiliary lighting unit can be rotated and adjusted through the design of individual rotating shafts 7 to increase the lighting coverage range of the reflective display screen. The angle θ range of the rotating shaft 7 allowed for each horizontal auxiliary lighting unit is: 0 degree ≤ θ ≤ 90 degrees. To obtain the best auxiliary lighting coverage effect, it is recommended that the LED series length lH of each horizontal auxiliary lighting unit satisfy: 1 / 4 of the horizontal width X of the effective display area ≤ lH ≤ 1 / 2 of the effective reflective display width X.

[0080] One or more vertical auxiliary lighting units are configured on the left / right side of the reflective display screen. Each vertical auxiliary lighting unit is composed of a plurality of LED lamp beads 6 to meet the incident light requirements for side lighting of the reflective display screen, and the lighting range of the vertical auxiliary lighting unit can be rotated and adjusted through the design of individual rotating shafts 7 to increase the lighting coverage range of the reflective display screen. The angle R range of the rotating shaft 7 allowed for each vertical auxiliary lighting unit is: 0 degree ≤ R ≤ 90 degrees.

[0081] To obtain the best auxiliary lighting coverage effect, it is recommended that the LED series length lV of each vertical auxiliary lighting unit satisfy: 1 / 2 of the horizontal height Y of the effective display area ≤ lV ≤ the effective reflective display height Y.

[0082] Embodiment (2): Embodiment (2), as Figure 3 and 5 shown, is basically the same as Embodiment (1), and the main difference lies in that the reflective display module uses a non-planar (curved) display screen.

[0083] The advantages of Embodiment (2) can be referred to the lighting light reflection relationship shown in Fig. 6(a) planar screen and Fig. 6(b) curved screen. Taking the lighting of the end LED lamp bead 6 of the auxiliary lighting unit as an example, due to distance limitations, the lighting effect of the end LED lamp bead 6 is the worst. Under the same LED light-emitting range, the same emitted light can help increase the verticality of the incident light on the reflective screen (R2 < R1) through the curvature change of the reflective screen, helping to obtain better reflection characteristics and efficiency utilization.

[0084] Embodiment (3): Each auxiliary lighting unit includes a plurality of LED light-emitting lamp beads, and the lamp beads are designed with a fixed or unequal pitch (pitch) electrical series relationship.

[0085] As Figure 7 shown, when the pitch of the LED lamp beads 6 is closely designed, a stronger unit illumination intensity can be obtained, so that the reflective screen can obtain a higher incident light quantity. When the pitch of the LED lamp beads 6 is loosely designed, a lower unit illumination intensity will be obtained, so that the reflective screen can obtain a lower incident light quantity.

[0086] As Figure 8 shown, a schematic diagram of the illumination of an auxiliary lighting unit. Taking the boundary illumination light of LEDs at different positions as an example, the near illumination optical path (S1) provided by the LEDs near the rotating shaft 7 is shorter. At the illumination position of the reflective screen, a higher incident illumination brightness can be obtained. However, the far illumination optical path (S2) provided by the LEDs relatively far from the rotating shaft 7 is longer. At the illumination position of the reflective screen, only a lower incident illumination brightness can be obtained. Furthermore, the difference in the incident light intensity at different positions of the reflective screen is formed, resulting in uneven reflectivity and affecting the display quality.

[0087] Therefore, for an auxiliary lighting unit, the advantage of adopting a fixed LED lamp bead pitch design is simple structure, and the limitation is that it is easy to cause uneven reflectivity of the reflective screen. If the unequal pitch design is adopted, the advantage is that it can adjust and compensate for the difference in incident light brightness caused by different optical path differences according to the difference in the illumination optical path of LEDs at different positions, so that the reflective screen can evenly reflect the image and help achieve a better auxiliary lighting effect. When the LED lamp beads adopt an unequal pitch design, it is recommended to adopt a sparse pitch design at the end near the rotating shaft 7 and a dense pitch design at the end far from the rotating shaft 7. The above reasonable pitch is recommended to be 1 mm to 30 mm; in addition, the total number of LED lamp beads can be determined according to different illumination brightness and power consumption specification requirements.

[0088] Embodiment (4): Each auxiliary lighting unit includes a plurality of LED lamp beads. Each LED lamp bead 6 can have a fixed projection angle P or adjust different projection angles P. Referring to Fig. 9(a), the light is emitted at the orthogonal projection angle P of the LED. Fig. 9(b) shows the light emitted at the adjusted projection angle P of the LED. For the same LED and light-emitting range, by adjusting the projection angle P of the LED, it can help obtain a larger effective projection range and increase the incident light angle of the reflective screen, so as to improve the display characteristics; as shown in Fig. 10(a), the light is emitted at the orthogonal projection angle P of the LED. Fig. 10(b) shows the light emitted at the adjusted projection angle P of the LED. For the same LED pitch design, the same LED light-emitting range, and the LEDs arranged in electrical series, the effective projection range can also be improved by adjusting the projection angle. It is recommended that the projection angle P of the LED be 0 degrees to 80 degrees.

[0089] As shown in FIGS. 11(a), 11(b), and 11(c), the LED projection angle adjustment method of the auxiliary lighting unit proposed in the present invention can be achieved by combining conventional mechanical means, such as link groups, sector handles, rockers, cams, gears, racks, etc. For example, in FIG. 11(a), a double-rocker mechanism is adopted. The double-rocker mechanism is a four-bar hinge mechanism in which both connecting rods are rockers, and it is called a double-rocker mechanism. In the mechanism, the two rockers can be the driving members respectively. The LED lamp beads are installed on the relative outer side wall of one of the rockers of the double-rocker mechanism, and the other rocker acts as the driving member to drive the rocker installed with the LED lamp beads to change the relative position, thereby adjusting the LED projection angle. As shown in FIG. 11(b), a rocker-cam mechanism is adopted. The LED lamp beads are installed on the surface of one side of the rocker, and the other end of the rocker is driven by a cam to swing, thereby changing the LED projection angle; as shown in FIG. 11(c), a gear-rack mechanism is adopted. The LED lamp beads are installed on the gear and rotate with the gear. The gear meshes with the rack, and the reciprocating movement of the rack drives the gear to rotate reciprocally within a set range, thereby changing the LED projection angle.

[0090] Embodiment (5): For the reflective display module proposed in the present invention, surface processing or external film materials can be used to endow the surface of the reflective display screen with surface characteristic functions such as AG (Anti-Glare) and LR (Low-Reflection). The purpose is to make the external incident light enter the surface of the reflective screen, undergo diffuse reflection, reduce glare, and reduce the interference of seeing the LED light shadow mapping. The function of the LR surface treatment is to make the external incident light enter the surface of the reflective screen, suppress the surface reflection interference, and help the reflective screen improve the contrast and color accuracy.

[0091] In addition, due to the present utility model having the optimal adjustment characteristics of the lighting projection range and the incident light angle, it can support and be applicable to various reflective display technologies with different degrees of severity of incident light conditions, including Optically Compensated Birefringence mode Reflective LCD technology, Cholesteric mode Reflective LCD technology, Electrophoretic display technology, and electrowetting display technology.

[0092] The utility model adopts the above technical solutions, and supports characteristics and requirements such as multi-sided and flexible auxiliary light source illumination, convenient storage, adjustable projection incident light angle and illumination range, and providing the incident light angles required by various reflection display technologies. The utility model overcomes the problems of size support limitation, excessive cost, space occupation, reflection effect limitation, etc. of the existing auxiliary light source technology.

Without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Generally, the components of the embodiments of this application described and illustrated in the drawings here can be arranged and designed in various different configurations.
