The at least one light sensor 160 is disposed between the upper polarizer 140 and the lower polarizer 150; each of the photo sensors 160 is electrically connected to the control chip 170.
In summary, in the embodiment, the optical sensor is disposed in the liquid crystal display module of the electronic device; the problem that in the prior art, the light sensor is arranged through the opening, and the collected environment light brightness is inaccurate due to the fact that the light sensor is limited by the angle and the light source direction when the environment light brightness is collected is solved; because the optical sensor is arranged in the LCD panel, the optical sensor is not limited in a certain small hole when collecting optical signals, and the accuracy of the ambient light brightness collected by the optical sensor is improved.
Fig. 2 is a schematic structural view illustrating a liquid crystal display module according to another exemplary embodiment. The liquid crystal Display component may be an LCD (liquid crystal Display) panel of an electronic device such as a mobile phone, a tablet computer, a notebook computer, a smart television, and the like.
As shown in fig. 2, the liquid crystal display assembly includes: the liquid crystal display panel includes an upper substrate 210, a lower substrate 220 disposed in parallel with the upper substrate 210, a liquid crystal layer 230 enclosed between the upper substrate 210 and the lower substrate 220, an upper polarizer 240 attached to a surface of the upper substrate 210 not adjacent to the liquid crystal layer 230, and a lower polarizer 250 attached to a surface of the lower substrate 220 not adjacent to the liquid crystal layer 230.
Alternatively, as shown in fig. 2, the upper substrate 210 includes: an upper glass substrate 211 and a CF 212. The lower surface of the upper glass substrate 211 is adjacent to the liquid crystal layer 230, and the CF212 is attached to the upper surface of the upper glass substrate 211. The CF212 enables the LCD panel to present color pictures, and a plurality of R, G, B color blocks with different pixels corresponding to three colors are arranged on the CF 212. As shown in fig. 3, several different arrangements of pixel patches on the CF are exemplarily shown. In a first possible arrangement, the color blocks of different pixels corresponding to the three colors CF31 and R, G, B are arranged in stripes. In a second possible arrangement, the different pixel patches corresponding to the three colors CF32, R, G, B are arranged in a triangle. In a third possible arrangement, the different pixel patches corresponding to the three colors CF33, R, G, B are arranged in a square shape. In a fourth possible arrangement, the color blocks of different pixels corresponding to the three colors CF34 and R, G, B are shown in a mosaic arrangement (or referred to as a diagonal arrangement). Of course, the several arrangements shown in fig. 3 are merely exemplary and illustrative, and the present embodiment is not limited to other possible arrangements.
Additionally, referring to fig. 2 and 4 in combination, fig. 4 shows a side view of a CF 212. The CF212 includes pixel patches 212a and Black matrices (Black Matrix)212b distributed among the respective pixel patches 212 a. The pixel patches 212a are different pixel patches corresponding to R, G, B. Black matrixes 212b are distributed among the pixel patches 212 a. The black matrix 212b serves to prevent leakage of background light, improve display contrast of the LCD panel, prevent color mixing, and increase purity of color.
Alternatively, as shown in fig. 2, the lower substrate 220 includes: a lower glass substrate 221 and a TFT array 222. Wherein, the upper surface of the lower glass substrate 221 is adjacent to the liquid crystal layer 230; a TFT array 222 is disposed on an upper surface of the lower glass substrate 221.
As shown in fig. 2, the liquid crystal display module further includes: at least one light sensor 260 and a control chip 270. Each of the light sensors 260 is disposed between the upper polarizer 240 and the lower polarizer 250. For example, each of the light sensors 260 may be disposed on the upper surface of the lower glass substrate 221; for another example, each of the light sensors 260 may also be disposed on a surface of the liquid crystal layer 230 adjacent to the upper glass substrate 211; as another example, each light sensor 260 may also be disposed on the CF212, and so on. Each of the photo sensors 260 is electrically connected to the control chip 270. The optical sensor 260 is used for converting the optical signal into an electrical signal and providing the electrical signal to the control chip 270.
Alternatively, when the number of the photo sensors 260 is plural, for example, when the number of the photo sensors 260 is n (n ≧ 2), the n photo sensors 260 are arranged uniformly and dispersedly. For example, in fig. 4, the respective photosensors 260 are uniformly and dispersedly arranged on the CF 212. By arranging the plurality of light sensors 260 and uniformly and dispersedly arranging the plurality of light sensors 260, it can be avoided that all the light sensors 260 are completely shielded by fingers or other objects of a user due to the operation of the user on the LCD panel, so that even if some light sensors 260 are shielded, another part of the light sensors 260 are still not shielded, and the other part of the light sensors 260 which are not shielded can still acquire accurate sensor data.
in addition, each of the photosensors 260 includes a photosensitive element disposed toward the upper polarizer 240 side, ensuring that a light signal is normally received. The photosensitive element includes, but is not limited to, any one of a photoresistor, a photodiode, a phototransistor, and a silicon photocell. The photosensitive element is used for converting optical signals into electric signals. Alternatively, the photosensitive element may be made of a transparent material.
in one possible implementation, as shown in fig. 4, the respective photosensors 260 are disposed on the black matrix 212b of the CF 212. For example, when there are a plurality of photosensors 260, the plurality of photosensors 260 are uniformly and dispersedly arranged on the black matrix 212b of the CF 212. By disposing the photo sensor 260 on the black matrix 212b, it can be ensured that the light transmittance of the LCD panel is not disturbed by the disposition of the photo sensor 260, thereby ensuring that the display effect of the LCD panel is not affected.
alternatively, referring to fig. 4 in combination, the light sensor 260 and the control chip 270 are connected by wires 280, and each wire 280 is also disposed on the black matrix 212b of the CF 212. By also disposing the conductive lines 280 on the black matrix 212b, it can be ensured that the disposition of the conductive lines 280 does not interfere with the transmittance of the LCD panel, thereby ensuring that the display effect of the LCD panel is not affected. Alternatively, the wire 280 may be made of a transparent material.
As shown in fig. 2, the liquid crystal display assembly may further include: at least one backlight 290. The at least one backlight 290 is electrically connected to the control chip 270. The backlight 290 is disposed on the back of the lower polarizer 250. Backlight 290 is used to provide a light source behind the LCD panel. The type of the backlight 290 includes, but is not limited to, any one of EL (Electro luminescence), CCFL (Cold Cathode Fluorescent Lamp), LED (Light Emitting Diode), and the like.
in addition, the control chip 270 may be an MCU (micro controller Unit), which is also called a single-chip microcomputer or a single-chip microcomputer, and is a chip-level computer. In a possible implementation manner, taking the MCU as an example to dynamically adjust the backlight brightness according to the ambient light brightness, each of the light sensors 260 collects the ambient light brightness, the MCU obtains the ambient light brightness from each of the light sensors 260, calculates the obtained ambient light brightness, determines the backlight brightness according to the calculation result, and controls the backlight source 290 to emit light according to the determined backlight brightness. For example, when the ambient light brightness is high, the light emitting brightness of the backlight 290 is controlled to be high; when the ambient light brightness is small, the light emitting brightness of the backlight 290 is also controlled to be small.
In addition, the display area corresponding to the liquid crystal display module may be a complete display area, and the display area is correspondingly provided with at least one backlight source 290. Each backlight 290 is used to control the backlight brightness throughout the display area.
Or, optionally, as shown in fig. 5, the display area 51 corresponding to the liquid crystal display assembly is divided into m (m ≧ 2) display blocks (such as the illustrated first display block 52, second display block 53, third display block 54, and fourth display block 55), each display block is correspondingly provided with at least one backlight 290, and each display block is correspondingly provided with at least one light sensor 260. For each display block, the corresponding backlights 290 are used to individually control the backlight brightness of the display block. For example, if the first display area 52 is correspondingly provided with a first backlight source and a first light sensor, and the second display area 53 is correspondingly provided with a second backlight source and a second light sensor, the first backlight source is used for individually controlling the backlight brightness of the first display area 52 according to the ambient light brightness collected by the first light sensor, and the second backlight source is used for individually controlling the backlight brightness of the second display area 53 according to the ambient light brightness collected by the second light sensor. The display area corresponding to the LCD panel is divided into a plurality of display blocks, and the backlight brightness of the display blocks is controlled in a partition mode by different backlight sources, so that the flexibility of backlight control is improved.
In summary, in the embodiment, the optical sensor is disposed in the liquid crystal display module of the electronic device; the problem that in the prior art, the light sensor is arranged through the opening, and the collected environment light brightness is inaccurate due to the fact that the light sensor is limited by the angle and the light source direction when the environment light brightness is collected is solved; because the optical sensor is arranged in the LCD panel, the optical sensor is not limited in a certain small hole when collecting optical signals, and the accuracy of the ambient light brightness collected by the optical sensor is improved. In addition, because the independent hole opening is not needed, the area of the front panel of the electronic equipment can be saved, and the integral design aesthetic feeling of the electronic equipment is improved.
In addition, the optical sensor is arranged on the black matrix of the CF, so that the arrangement of the optical sensor cannot interfere with the light transmittance of the LCD panel, and the display effect of the LCD panel is not influenced.
In addition, the plurality of optical sensors are arranged and are uniformly and dispersedly arranged, so that the situation that all the optical sensors are completely shielded by fingers or other objects of a user due to the operation of the user on the LCD panel can be avoided, and even if some optical sensors are shielded, the other part of the optical sensors are still not shielded, and the other part of the optical sensors which are not shielded can still acquire accurate sensor data.
