The conductive layer 410 has a large area so that a sufficiently stable second capacitance can be formed with the common electrode layer 130, and alternatively, the area of the conductive layer 410 may be more than 40% of the area of the display screen. The conductive layer 410 may be an existing structure in the display screen or an independently-added structure, and when the former embodiment is adopted, the structural change of the display screen is small, and the thickness of the display screen is basically not increased due to the conductive layer 410, so that the thickness of the display screen is favorably controlled; when the latter embodiment is adopted, the structure of the conductive layer 410 is not restricted by the existing structure of the display screen, so that parameters such as the material and the size of the conductive layer 410 can be flexibly selected, and the performance of the second capacitor can be improved.
The common electrode layer 130 and the conductive layer 410 are electrostrictive members, and both of them can be deformed by an electric field, thereby generating vibration.

When the vibration sounding scheme disclosed by the embodiment of the application is adopted, the frequency of the sounding can reach K level, and the frequency can meet the condition that a user can hear after modulation.
As can be seen from the above, in the display panel disclosed in the embodiment of the present application, the second capacitor formed by the common electrode layer 130 and the conductive layer 410 may form an electric field, and the electric field may act on the common electrode layer 130 and the conductive layer 410, so that the common electrode layer 130 and the conductive layer 410 vibrate, and the display panel may vibrate to generate sound. This scheme utilizes the structure of display screen self to realize the vibration sound production, no matter how the weight of display screen, all can realize the vibration of display screen through the flexible display screen that realizes of common electrode layer 130 and conducting layer 410, and this kind of scheme can be applicable to the display screen of arbitrary weight, therefore this scheme can be so that carry out the technique of sound production through the display screen vibration and realize more easily, has widened the application scope of this technique.
In addition, the display screen can be directly driven to produce sound, and sound signals do not need to be transmitted step by step, so that the attenuation of acoustic parameters such as frequency and amplitude of the produced sound is small, and the sound production effect is good. When the display screen in the embodiment of the application produces sound, the functions of sound producing devices such as a receiver and a loudspeaker can be realized, so that the number of the sound producing devices can be reduced, and even the sound producing devices do not need to be additionally arranged, so that the number of parts of the electronic equipment adopting the display screen can be greatly reduced, the cost of the electronic equipment is lower, and the difficulty of the structural design can be reduced accordingly.
The display module refreshes the display content once every unit time length T, optionally, the refresh frequency of the display screen can be 60Hz, 60 frames are refreshed every second, and in the time corresponding to each frame, the display and the touch detection of the display screen are multiplexed in a time sharing mode, namely, one part of the time corresponding to each frame is used for displaying, and the other part of the time is used for touch detection. Optionally, a driver may be additionally provided for driving the vibration function of the display screen, or the unit time length T may be redistributed, so that the display, touch detection and vibration functions are simultaneously implemented within the unit time length T. In this embodiment, the unit duration T includes a display period T1, a touch detection period T2, and a vibration period T3, and is time division multiple access, in which: under the condition that the display module is in the display time period t1, the first capacitor is in a working state, and at the moment, the state of the liquid crystal layer 220 or the organic light emitting layer 370 can be controlled through the first capacitor, so that the display function is realized; under the condition that the display module is in the touch detection time period t2, the common electrode layer 130 forms a plurality of detection units, and each detection unit is applied with a touch detection signal, so as to realize the function of touch detection; in the case where the display module is in the vibration period t3, the second capacitor is in an operating state, and the control device applies a driving signal to at least one of the common electrode layer 130 and the conductive layer 410 to vibrate the common electrode layer 130 and the conductive layer 410.
After the mode is adopted, the display, touch detection and vibration functions of the display screen can be simultaneously realized within the same unit time length T, so that the vibration control can be realized according to the requirements of a user when refreshing at every time, and the display screen can be controlled to vibrate more conveniently and more sensitively. In addition, can drive the display screen sound production with the help of being used for driving the driver chip 340 that the display screen shows and touch-control detects, and need not additionally set up the higher special chip of cost to save the space that mainboard 350 was occupied, the components and parts overall arrangement on the mainboard 350 of being more convenient for reduces the cost of display screen simultaneously.
As shown in fig. 3, when the display module is in the display period t1, the common electrode layer 130 is used as the lower plate of the first capacitor and has no signal. Under the condition that the display module is in the touch detection time period t2, the common electrode layer 130 is divided into a plurality of detection units, each detection unit receives a square wave signal with the same frequency and the same phase, the amplitude of the square wave signal can be about 2.5V, a finger of a user can be equivalently grounded, when the finger touches the display screen, the capacitance value of the second capacitor can be changed, meanwhile, in combination with fig. 4, when the display screen receives the square wave pulse S1, the second capacitor is charged, and when the display screen receives the square wave pulse S2, the driving chip 340 detects the capacitance value change of the second capacitor through the common electrode layer 130, so as to determine whether the display screen is touched and the touched position. Under the condition that the display module is in the vibration time period t3, the common electrode layer 130 may receive a square wave signal that can be modulated, and acoustic signals with different frequencies and sizes may be modulated by changing parameters such as the amplitude and duty ratio of the square wave signal. Of course, in the case that the display module is in the vibration period t3, the common electrode layer 130 may also receive a sine wave signal or other types of signals, and the square wave signal is relatively more convenient for modulating the target sound signal.
As described above, when the display screen is a liquid crystal display screen, in the case that the display screen module is in the display period t1, the liquid crystal of the liquid crystal layer 220 is deflected by the driving action of the first capacitor, so that the display function of the display screen is realized. In this embodiment, the backlight assembly may include a first metal frame 510, and a reflective film 520, a light guide plate 530, a diffusion film 540 and a brightness enhancement sheet 550 sequentially stacked on the first metal frame 510, wherein the brightness enhancement sheet 550 may be disposed in one layer or in multiple layers, and adjacent brightness enhancement sheets 550 may be connected by a light shielding adhesive 560. The first metal frame 510 may serve as a base for disposing the reflective film 520, the light guide plate 530, the diffusion film 540, and the brightness enhancement sheet 550. Since the first metal frame body 510 is made of a metal material, it has conductivity, and the first metal frame body 510 is large in size, and can satisfy the condition as the conductive layer 410, so that the first metal frame body 510 can be made as the conductive layer 410. This embodiment uses the existing structure of the backlight assembly to realize the requirement of the second capacitor formed by the conductive layer 410 and the common electrode layer 130, and does not need to additionally provide the conductive layer 410, thereby simplifying the structure of the display screen.
When the display screen is an organic light emitting display screen, as described above, the organic light emitting layer 370 emits light under the driving action of the first capacitor when the display module is in the display period t 1. At this time, the display screen further includes a conductive metal layer disposed on the array substrate 110, and the conductive metal layer is used as the conductive layer 410. That is, the conductive metal layer can be additionally provided, so that the vibration sound emission function of the display screen can be realized for the organic light emitting display screen, and the manufacturing material of the conductive metal layer can be designed with the purpose of improving the performance related to vibration sound emission such as vibration sound emission effect, so that the vibration effect of the display screen can be improved more easily.
Based on the display module assembly, this application embodiment still discloses an electronic equipment, and it includes casing and above-mentioned arbitrary embodiment the display module assembly, this display module assembly sets up in the casing.
