Referring to fig. 1, the liquid crystal display for displaying medical diagnostic images of the present embodiment may include a chassis (not shown) in which a backlight module 1, a display module 2, and an optical film layer 3 are disposed. The optical film layer 3 is located between the backlight module 1 and the display module 2, a power socket can be arranged on the casing, and the display module and the backlight module are electrically connected with the power socket so as to supply power to the display through the power socket.
The backlight module 1 may be referred to as a light source module, a lighting module, a backlight assembly, etc., the display module 2 may be referred to as a liquid crystal display panel, a display assembly, a panel module, a panel assembly, etc., and the optical film layer 3 may be referred to as a modulation film layer, a functional film layer, a display enhancement film layer, etc.
The light emitted by the backlight module 1 can be uniformly diffused to the whole display panel area of the display module 2, specifically, the light emitted by the backlight module 1 reaches the display panel of the display module 2 after being modulated by the optical film layer 3, and different kinds of optical film layers 3 can realize various different functions, such as improving the contrast ratio and brightness of the display panel of the display module 2 or enhancing the color expression of the display panel of the display module 2.
The backlight module 1 may include a base light assembly 11 and an enhanced light assembly 12. Wherein the basic light component 11 is configured to provide basic light to the display module 2, so that the display module 2 has a first brightness; the light enhancement component 12 is configured to provide enhancement light to the display module 2, so as to match the basic light provided by the display module 2 to make the display module 2 have a second brightness, where the second brightness is higher than the first brightness; the optical film layer is used for carrying out optical treatment on the basic light and the enhanced light. For example, the first luminance may be 250-300cd/M2 (candela per square meter) and the second luminance may be greater than or equal to 1000cd/M2 (candela per square meter).
In the lcd according to the embodiment of the present invention, the basic light component 11 of the backlight module 1 is configured to provide basic light for the display module 2 so that the display module 2 has a first brightness, and the light enhancing component 12 of the backlight module 1 is configured to provide enhanced light for the display module 2 so that the display module 2 has a second brightness in cooperation with the basic light provided by the display module 2, where the second brightness is higher than the first brightness, so that the brightness of the display screen of the lcd can be improved by cooperation of the enhanced light component 12 or the enhanced light and the basic light.
In some embodiments, the primary light assembly 11 includes a back plate 13 and a first set of light sources 14 disposed on a first side of the back plate 13, the first side of the back plate 13 being a side of the back plate 13 proximate to the optical film layer; light emitted by the first set of light sources 14 can enter the display module 2 through the optical film layer. Thus, the light emitted by the first group of light sources 14 directly enters the display module 2, so that the light loss can be reduced, and the peak brightness of the display module 2 can be improved, thereby enabling the display module 2 to provide brighter pictures.
In addition, the light rays emitted by the first group of light sources 14 directly enter the display module 2, so that the attenuation degree of the light rays in each area is basically the same, the light rays are distributed on the display module 2 more uniformly, and the risk of darkening of the edge of a display picture of the display module is reduced.
In some embodiments, the light enhancement assembly 12 includes a second set of light sources 15 disposed on a first side of the back plate 13, the light emitted by the second set of light sources 15 being capable of entering the display module 2 through the optical film layer.
The technical effect of the arrangement of the second group of light sources 15 of the enhanced light assembly 12 provided in this embodiment is substantially the same as the technical effect of the arrangement of the first group of light sources 14 of the basic light assembly 11, and will not be described in detail herein.
Referring to fig. 2, in some embodiments, the first set of light sources 14 and the second set of light sources 15 each include a plurality of light beads; the plurality of light beads of the second set of light sources 15 and the plurality of light beads of the first set of light sources 14 are arranged on the first side of the back plate 13 in a crossing manner, so that the second set of light sources 15 can fill gaps among the plurality of light beads of the first set of light sources 14, uniformity of light rays emitted by the backlight module 1 is improved, brightness of basic light provided by the first set of light sources 14 is reduced, and brightness of enhanced light provided by the second set of light sources 15 is different, so that display effect of the display module 2 is affected. Alternatively, the light beads may be LED light sources. 141 in fig. 2 represents one bead of the first set of light sources 14, 142 represents another bead of the first set of light sources 14; 151 denotes one bead of the second set of light sources 15 and 152 denotes another bead of the second set of light sources 15.
When the plurality of light beads of the second group of light sources 15 are arranged to cross the plurality of light beads of the first group of light sources 14, the adjacent light beads can reflect light mutually, so that more light irradiates the backlight module 1, the luminous flux of the backlight module 1 is increased, and the display panel of the display module 2 has higher brightness. The luminous flux refers to the quantity of light emitted by the backlight module 1 in a unit time.
In order to improve the brightness of the display screen of the lcd, in some embodiments, the distribution area of the first set of light sources 14 and the second set of light sources 15 on the surface of the back plate 13 facing the display module 2 is greater than 75% of the total area of the surface of the back plate 13 facing the display module 2. In one embodiment, the ratio is 80%.
In order to solve the problem, in some embodiments, the light enhancement module 12 includes a first group of light enhancement sources, a second group of light enhancement sources, a first light source controller and a second light source controller; the first light source controller is electrically connected with the first group of enhanced light sources, and the second light source controller is electrically connected with the second group of enhanced light sources.
The first group of enhanced light sources and the second group of enhanced light sources can be respectively used for providing enhanced light for the display module 2 so as to match the basic light provided by the display module 2 to enable the display module 2 to have second brightness. Therefore, the first group of reinforcing light sources can be controlled by the first light source controller to provide reinforcing light for the display module 2, when the first group of reinforcing light sources provide reinforcing light for the display module 2, and the display module 2 cannot have second brightness, the second group of reinforcing light sources are controlled by the second light source controller to provide reinforcing light for the display module 2, and the display module 2 has second brightness in cooperation with basic light provided by the display module 2, so that the service life of the liquid crystal display is prolonged.
To facilitate the enhancement light component 12 to provide the enhancement light to the display module 2, the display module 2 has a second brightness in cooperation with the basic light provided by the display module 2, and in some embodiments, the liquid crystal display further includes an illumination sensor, where the illumination sensor is electrically connected to the second light source controller; the first light source controller and the second light source controller may include a backlight control board and a logic board, respectively, and the backlight control board and the logic board are electrically connected, and the illumination sensor may be electrically connected with the logic board of the second light source controller. Electrical connection includes making electrical connection through wires or making electrical connection by way of wireless communication.
A first group of enhanced light sources in the enhanced light assembly 12 is configured to provide enhanced light to the display module 2, so as to match the basic light provided by the display module 2 to enable the display module 2 to have a second brightness; the illumination sensor is used for monitoring the current brightness of the display module 2, if the current brightness of the display module 2 is lower than the preset brightness threshold, a control signal is sent to the second light source controller, so that the second light source controller controls the second group of enhanced light sources to provide enhanced light for the display module 2, and thus the enhanced light provided by the enhanced light component 12 can be timely and conveniently adjusted, and the display module 2 always has the second brightness.
The preset brightness threshold may be the second brightness, or may be slightly higher or slightly lower than the second brightness.
In some embodiments, the backlight module 1 of the lcd provided in the embodiments of the present invention includes a basic light assembly 11 and an enhanced light assembly 12, and the basic light assembly 11 and the enhanced light assembly 12 are controlled to enable the display module 2 to have three brightness values: providing a first luminance of the primary light only by the primary light assembly 11, providing a third luminance of the enhanced light only by the enhanced light assembly 12, and providing a second luminance of the primary light and the enhanced light both by the primary light assembly 11 and the enhanced light assembly 12, wherein the third luminance is located between the first luminance and the second luminance; in this way, better display effect can be obtained by using different backlight brightness under different ambient light conditions, for example, the display screen is clearer by using the second brightness in a bright environment, and glare is reduced by using the first brightness in a dark environment.
Compared with the method for only providing the highest brightness value to ensure the definition of the display picture, the display module 2 has three brightness values, and the proper brightness value is selected according to the actual environment condition, so that the power consumption of the liquid crystal display can be saved while the definition of the display picture is ensured.
Optionally, according to the specific display brightness requirement of the display module 2, the backlight module 1 may further be provided with other light components capable of providing light corresponding to different brightness values.
In some embodiments, the first set of light sources 14 and the second set of light sources 15 each comprise a plurality of light beads; the plurality of light beads of the second set of light sources 15 are arranged in an array on the back plate 13, and the number of the light beads of the first set of light sources 14 and the number of the light sources of the second set of light sources 15 accord with a preset proportional relationship. In one example, 4 or 5 light beads of the first group of light sources 14 are arranged around each light bead of the second group of light sources 15.

In this way, the first group of light sources 14 and the second group of light sources 15 are dispersed at different positions of the back plate 13, so that the heat can be conveniently and uniformly distributed and dispersed, and the problem of local overheating is avoided.
Wherein, the end of the back plate 13 refers to the side perpendicular to the first side of the back plate 13, which may also be referred to as the left side of the back plate 13 or the right side of the back plate 13; the second set of light sources 15 may include a plurality of light beads 14. The second group of light sources 15 is disposed at the end of the back plate 13 so that the light emitted by the second group of light sources 15 can enter the back plate 13 through the end of the back plate 13, and therefore, the second group of light sources 15 is not necessarily fixed to the end of the back plate 13.
It should be understood that, in the first set of light sources 14 provided on the first side of the back plate 13, adjacent light beads have a predetermined interval therebetween, and that on the back plate 13, there is exit light refracted after light passing through the second set of light sources 15 enters the back plate 13 at the interval between the adjacent light beads.

In this way, the light guide plate can perform optical treatments such as scattering, refraction and reflection on the light emitted by the first group of light sources 14 and the second group of light sources 15 through the internal microstructure, so that the light emitted by the first group of light sources 14 and the second group of light sources 15 is uniformly dispersed on the surface of the whole light guide plate to be emitted, and the loss of the light emitted by the first group of light sources 14 and the second group of light sources 15 in the propagation process is reduced, thereby improving the display brightness of the liquid crystal display.
