Embodiment
Please refer to Fig. 1, this figure is depicted as the first embodiment synoptic diagram of the display device with inducing function.Display device with inducing function of the present invention comprises: the display panels 10 and the line of induction 20.
Many lines of induction 20 are arranged between the two adjacent data lines 12, and being configured to of each bar line of induction and 12 of data lines is parallel, and with 14 of sweep traces be configured to vertical.Wherein, the line of induction 20 is in order to transmit touching signals.
The kind of display panels 10 proposed by the invention is: suppose that display panels has the pixel of M*2N, and display panels 10 just has the data line 12 that adds up to the N bar, and add up to the sweep trace 14 of 2M bar, wherein M and N are all positive integer.That is to say that the former data line 12 that should have the 2N bar, utilizes a data line 12 to control left pixel LP and right pixel RP, thereby can reduce the number that is provided with of data line 12 in this to electrically connect the configuration scenario of left pixel LP and right pixel RP respectively.And originally the space of configuration data line 12 still exists, but then belongs to the not zone of wiring in this display panels 10, so the present invention utilizes this zone of not connecting up, that is between the two adjacent data lines 12, and with the line of induction 20 configurations wherein.So, not only make full use of originally the not space of wiring, more can make display panels 10 have inducing function as the contact panel, and not need the extra space that increases the configuration line of induction.
Please refer to Fig. 2 is the second embodiment synoptic diagram with display device of inducing function.In Fig. 2, can further find out framework of the present invention.Beneath at the more detailed explanation of the do of the assembly connection relationship in the display device of inducing function of the present invention.
Please continue with reference to Fig. 2, wherein pixel region 30 comprises first pixel region 32 and second pixel region 34 of sharing sweep trace 14, first pixel region 32 and the 34 adjacent settings of second pixel region, and each bar data line 12 is electrically connected to the right pixel RP of first pixel region 32 and the left pixel LP of second pixel region 34.
Pixel region 30 comprises a plurality of gauge tap 40, and gauge tap 40 is electrically connected to sweep trace 14 and data line 12, and the gauge tap 40 of the right pixel RP of the gauge tap 40 of the left pixel LP of pixel region 30 and pixel region 30 is electrically connected to adjacent scanning lines 14.
As previously mentioned, what display panels 10 of the present invention had a data line 12 adds up to the N bar, and sweep trace 14 add up to the 2M bar.Because this line of induction 20 is in order to transmitting touching signals, therefore, the configured number of the line of induction 20 can be according to the required inducing function of display panels 10, and has some change.When required sensing capability requirement is comparatively sensitive, configurable more the line of induction 20.Relative, when the requirement of inducing function comparatively during low order, configurable less the line of induction 20 is to reduce cost.Therefore, the sum that is provided with of the line of induction 20 can be between 1～N.
In addition, the present invention more comprises a plurality of inductive switches 50, is arranged at the line of induction 20 and sweep trace 14 staggered parts, and each inductive switch 50 correspondence respectively couples the line of induction 20 and sweep trace 14.As shown in Figure 2, inductive switch 50 is arranged in the pixel region 30.Inductive switch 50 is similar general use contact panel, when certain is some in pushing contact panel, inductive switch 50 just with share voltage (Vcom) conducting, at this moment, only the sweep trace 14 that needs inductive switch 50 to be coupled provides start signal, that is open (turn on) inductive switch 50, and touching signals just can enter the line of induction 20 that is coupled by inductive switch 50, and reach the function of touch-control sensing.Wherein, inductive switch 50 can be provided with its number according to the density of required induction.As shown in Figure 2, suppose that display panels 10 has the M row, shown in the figure, just is connected with M inductive switch 50 on single the line of induction 20.In this, the sum that is provided with of inductive switch 50 can be between 1～M.
In addition, data line 12 can send from the signal of video signal of specific use integrated circuit (ASIC) (videosignal), therefore must provide pixel to show required data voltage on data line 12.And the line of induction 20 can connect specific use integrated circuit (ASIC) equally, but need not provide pixel to show required data voltage.
Moreover, the aperture opening ratio in the simple declaration LCD (Aperture Ratio).It is exactly brightness that an important specification is arranged in the LCD, and the most important factor of decision brightness is an aperture opening ratio.So-called aperture opening ratio is exactly the permeable effective coverage of a light ratio briefly.When light emits via backlight, not all light can both pass panel, similarly be signal lead, the TFT itself that LCD device drive chip is used, and the storage capacitors used of stored voltage etc., these zones also because these regional light of process are not subjected to the control of voltage, and can't show correct GTG except incomplete printing opacity, so need utilize shading region (black matrix) to be covered, in order to avoid interfere with the correct brightness of other transmission region.So effectively the ratio of transmission region and entire area promptly is referred to as aperture opening ratio.
Please refer to Fig. 3 is the 3rd embodiment synoptic diagram with display device of inducing function.Pixel region 30 more comprises shading region 60 in the 3rd implements.Wherein, shading region 60 and the line of induction 20 overlapping settings.That is to say, the position that disposed of the line of induction 20 as previously mentioned, about being controlled between two pixels by adjacent data line 12, that is on the zone of not wiring.And the zone of wiring is not to utilize shading region 60 to be covered on using, in order to avoid interfere with the correct brightness of other transmission region.So, shading region 60 and the line of induction 20 both overlapping settings, also because both overlay configuration, even that is to say that the line of induction 20 is not put in the zone of wiring, covered by shading region 60, therefore, even the present invention is provided with the line of induction 20 in the zone of not connecting up, almost can not change to some extent the pixel aperture ratio (Aperture Ratio) of whole display panels 10 yet.
Please refer to Fig. 4, this figure is depicted as the process flow diagram of the display packing with inducing function, comprises the following step.
