Specific implementation mode
To keep the purpose, technical scheme and advantage of the application clearer, below in conjunction with attached drawing to the application embodiment party
Formula is described in further detail.
The brightness of each region light extraction of touching display screen is most important for the display effect of touching display screen.Since touch-control is aobvious
The light transmission rate in the touch control electrode region in display screen is less than the light transmission rate of lead areas, so the light that touch control electrode region is sent out
Brightness be less than the brightness of light that lead areas is sent out so that touching display screen will appear light and shade phase when being shown in illuminated state
Between striped (also referred to as disappear shadow phenomenon), display effect is poor.The utility model embodiment provides a kind of touching display screen, should
The brightness of each region light extraction of touching display screen is more uniform, avoids the generation of light and dark striped, and it is aobvious to improve touch-control
The display effect of display screen.
Fig. 1 is a kind of structural schematic diagram for touching display screen that the utility model embodiment provides.As shown in Figure 1, this is touched
Controlling display screen 10 may include：Light source layer 101, brightness adjustment layers 102 and touch control layer 103, and brightness adjustment layers 102 are located at light source

Corresponding second area 1022.It should be noted that the touch control layer of touching display screen can have multiple touch control electrode regions and more
A lead areas, and there is its corresponding first area in each touch control electrode region, each lead areas have its corresponding the
Two regions.One of touch control electrode region and a lead areas and a touch area pair are illustrated only in Fig. 1
The corresponding second area of the lead areas in the first area answered and this.
The light that light source layer 101 is sent out can pass through 1021 directive touch control electrode region 1031 of first area so that from touch-control
The brightness for the light that electrode zone 1031 projects is the first brightness a1, the light that light source layer 101 is sent out can pass through second area 1022
Directive lead areas 1032 so that the brightness of the light projected from lead areas 1032 is the second brightness a2。It can be less than
Default fractional threshold, at this point, human eye can not feel the first brightness a1With the second brightness a2Difference, that is to say it is considered that touch
The light that display screen projects brightness uniformity is controlled, without light and dark striped.
Exemplary, which can be 1%, that is to sayIt should be noted that | a1-a2|
For the first brightness a1With the second brightness a2Brightness absolute value of the difference,For the absolute value and the second brightness a2Ratio.
In conclusion the touching display screen that the utility model embodiment provides includes brightness adjustment layers, brightness adjustment layers
First area is corresponding with the touch control electrode region of touch control layer, the second area of brightness adjustment layers and the lead areas pair of touch control layer
Answer, and projected by first area the light in touch control electrode region brightness and the light by second area injection lead areas it is bright
It is smaller to spend difference.When touching display screen is shown in illuminated state, due under the action of the brightness adjustment layers, from touching display screen
The luminance difference for the light that each region is projected is smaller, avoids touching display screen and generates light and dark striped, and therefore, touch-control is aobvious
The display effect of display screen is preferable.
Optionally, which can be single layer touch control layer, and the material of the touch control layer 102 can be electrically conducting transparent material
Matter, if electrically conducting transparent material is tin indium oxide (English：Indium tin oxide；Referred to as：ITO).It is exemplary, the single layer touch-control

Light brightness it is higher.Blast block density can be the sum of area of all blast blocks and the region gross area in the region
Ratio, the spacing between blast block density and the shape of blast block and adjacent blast block is related.Since first area is corresponding
The light transmission rate in touch control electrode region is less than the light transmission rate of the corresponding lead areas of second area, so from touch control electrode region
The brightness of the light of injection is less than the brightness of the light projected from lead areas.Brightness adjustment can be set in the utility model embodiment
The blast block density of first area is more than the blast block density of second area in layer, so that the light projected from touch control electrode region
The brightness of line and the luminance difference of the light projected from lead areas are smaller so that touching display screen when being shown in illuminated state not
Generate light and dark striped.Exemplary, the blast block density of second area can be 0, and that is to say can be only in first area
Blast block is set, without blast block is arranged in second area.
It should be noted that first area blast block density and second area blast block density can according to brightness with
The default correspondence of blast block density is configured, and in the default correspondence blast block density of first area with from touching
The brightness for controlling the light that electrode zone projects is negatively correlated, the brightness of the blast block density of second area and the light projected from lead areas
It is negatively correlated.

The first area of different blast block density is respectively set in display screen, and counts from the corresponding touch control electrode area in each first area
The brightness for the light that domain is projected；Then, it is determined that the luminance difference of each brightness of statistics and the brightness of the light projected from lead areas, and
Calculate the ratio of each brightness absolute value of the difference and the brightness of the light projected from lead areas；Finally, minimum ratio is corresponded to
The blast block density of first area be determined as：The blast of the corresponding first area in touch control electrode region of this kind of touching display screen
Block density.
It should be noted that the ratio of the obtained minimum needs to be less than default fractional threshold (such as 1%), if the ratio
More than default fractional threshold, then need to continue to test so that minimum ratio is less than default fractional threshold.
Optionally, brightness adjustment layers 102 or dim layer, which, which can be used for weakening, injects the dim layer
The brightness of light, and project the light after weakening brightness.Exemplary, which can be only arranged at second area, to subtract
The brightness of the weak light projected from the corresponding lead areas of second area so that the brightness of the light projected from lead areas with from
The luminance difference for the light that touch control electrode region is projected is smaller, and touching display screen is avoided to generate light and dark striped.
