Please refer to fig. 1-2. Fig. 1 is a top view illustrating a display device 100 according to an embodiment of the present invention. Fig. 2 is a partial perspective lower view illustrating the display device 100 of fig. 1. As shown in fig. 1 to 2, the present invention provides a display device 100. For example, the display device 100 may be a load-type display device, and may allow a user to measure his or her electrocardiogram signal. The specific structure of the display device 100 is described in detail below.
Please refer to fig. 3-4. Fig. 3 is a front view illustrating the display device 100 of fig. 1, in which the thickness of the cover plate 160 is shown in an exaggerated scale. Fig. 4 is a partial enlarged sectional view showing a line A-A of fig. 1. In this embodiment, as shown in fig. 1 to 4, the display device 100 includes a display substrate 110, a circuit board 120, at least one conductive pad 130, at least one first double-sided tape 140, at least one conductive foam tape 150, and a cover 160. The display substrate 110 has a first region Z1 and at least a second region Z2 adjacent to each other. Specifically, the first region Z1 and the second region Z2 are located at a peripheral position of the display substrate 110 and are arranged along a side of the display substrate 110. The circuit board 120 is at least partially disposed in the first area Z1, and the first area Z1 may be actually an outgoing line area of the display substrate 110. The conductive pad 130 is disposed on the first surface 121 of the circuit board 120 opposite to the display substrate 110. The first double-sided tape 140 is disposed in the second zone Z2. The conductive foam tape 150 is disposed on the first double-sided tape 140 and the conductive pad 130. The cover 160 includes a transparent substrate 161 and at least one conductive layer 162. The light-transmitting substrate 161 may be, for example, a glass plate, and includes a second surface 163 facing the display substrate 110 and a third surface 164 facing away from the display substrate 110. The conductive layer 162 at least partially covers the peripheral region of the transparent substrate 161 and at least partially covers the second surface 163 and the third surface 164. The conductive foam tape 150 is at least partially disposed between the second surface 163 of the transparent substrate 161 and the conductive pad 130, and electrically connects the conductive layer 162 and the conductive pad 130.
In practical applications, the circuit board 120 may be, for example, a flexible printed circuit board (Flexible Printed Circuit; FPC) or a Chip On Film (COF). More specifically, if the display device 100 is a liquid crystal display (Liquid Crystal Display; LCD), the circuit board 120 may be connected to the lower substrate of the display module. If the display device 100 is an Organic Light-Emitting Diode (OLED) display or a Micro-LED (Microscopic Light-Emitting Diode) display, the circuit board 120 may be connected to a circuit substrate having a thin film transistor (Thin Film Transistor; TFT) or a microchip (Micro-chips) on a display panel.
As described above, since the conductive layer 162 at least partially covers the third surface 164 of the transparent substrate 161, by the user touching the conductive layer 162 covering the third surface 164 with, for example, a finger, the electrocardiographic signals of the user can sequentially pass through the conductive layer 162, the conductive foam tape 150, the conductive pad 130 and the circuit board 120, and be transmitted to a system (not shown) of the signal connection circuit board 120 for subsequent recording and analysis.
Specifically, as shown in fig. 4, the conductive foam tape 150 includes conductive foam 151 and a conductive double-sided tape 152. The conductive foam 151 abuts against the first double-sided tape 140 and the conductive pad 130, and the conductive double-sided tape 152 is connected between the conductive foam 151 and the conductive layer 162. In other words, the conductive foam 151 is in direct contact with the conductive pad 130, thereby facilitating conductivity therebetween. Moreover, since the conductive double-sided tape 152 is positioned only on one side of the conductive foam 151 and not on the other side, the conductive foam tape 150 has better compressibility, which is further advantageous for improving the conductivity of the conductive foam tape 150.
Further, as shown in fig. 4, the conductive double-sided tape 152 of the conductive foam tape 150 includes a conductive substrate 153, a first adhesive layer 154, and a second adhesive layer 155. The conductive substrate 153 includes a first side 156 and a second side 157 opposite. The first adhesive layer 154 is disposed on the first side 156 of the conductive substrate 153 and is configured to adhere to the conductive layer 162 of the cover 160. The second adhesive layer 155 is disposed on the second side 157 of the conductive substrate 153 and is configured to adhere the conductive foam 151 of the conductive foam tape 150. In practical applications, the conductive substrate 153, the first adhesive layer 154 and the second adhesive layer 155 are all made of conductive materials.
In addition, as shown in fig. 4, the first double-sided tape 140 includes a first substrate 141, a third adhesive layer 142, and a fourth adhesive layer 143. The first substrate 141 includes an opposite third side 144 and a fourth side 145. The third adhesive layer 142 is disposed on the third side 144 of the first substrate 141 and is configured to adhere the conductive foam 151 of the conductive foam tape 150. The fourth adhesive layer 143 is disposed on the fourth side 145 of the first substrate 141 and is configured to adhere to the display substrate 110. In practical applications, the first substrate 141, the third adhesive layer 142 and the fourth adhesive layer 143 may be made of conductive materials or non-conductive materials according to practical situations.
In addition, in practical applications, as shown in fig. 4, the number of the second regions Z2 is two, and the first region Z1 is located between the second regions Z2. The number of the first double-sided tapes 140 is also two, and the first double-sided tapes 140 are respectively disposed in the corresponding second regions Z2. The number of conductive pads 130 is also two, and the conductive pads 130 are separated from each other. The number of the conductive foam tapes 150 is also two, and the conductive foam tapes 150 are separated from each other and respectively disposed on the corresponding first double-sided adhesive tape 140 and the corresponding conductive pad 130. The number of the conductive layers 162 is also two, and the conductive layers 162 are separated from each other and electrically connected to the corresponding conductive foam tapes 150 respectively.
Further, in the present embodiment, as shown in fig. 4, the conductive foam 151 abuts against the corresponding conductive pad 130 and the third adhesive layer 142 of the corresponding first double-sided tape 140, and the conductive double-sided tape 152 is connected between the corresponding conductive foam 151 and the corresponding conductive layer 162.
Please refer to fig. 5. Fig. 5 is a partially enlarged cross-sectional view illustrating a display device 100 according to another embodiment of the present invention. In this embodiment, as shown in fig. 5, the display device 100 further includes a second double-sided tape 170. The second double-sided tape 170 is located between the conductive pads 130 to be spaced apart from the conductive pads 130, and the second double-sided tape 170 is connected between the conductive foam 151 of the conductive foam tape 150 and the circuit board 120. In this way, the second double-sided adhesive tape 170 can help to fix the relative position of the conductive foam tape 150 with respect to the circuit board 120, so that the electrical connection between the conductive foam tape 150 and the conductive pad 130 is more stable.
Further, as shown in fig. 5, the second double-sided tape 170 includes a second substrate 171, a fifth adhesive layer 172, and a sixth adhesive layer 173. The second substrate 171 includes an opposite fifth side 174 and a sixth side 175. The fifth adhesive layer 172 is disposed on the fifth side 174 and is configured to adhere to the conductive foam 151 of the conductive foam tape 150. The sixth adhesive layer 173 is disposed on the sixth side 175 and is configured to adhere to the circuit board 120. In practical applications, the second substrate 171, the fifth adhesive layer 172 and the sixth adhesive layer 173 may be made of conductive materials or non-conductive materials according to practical situations.
