UxTouch are LCD TFT displays with specially designed projected capacitive touch panels. UxTouch display can be mounted without any holed in the housing. Our standard UxTouch displays include double-sided adhesive tape (DST) to stick TFT easily to the housing.

UxTouch models with double-side adhesive tape (PN with endings 00, 01, 03, 04) can be mounted by connecting the glass to the housing. Riverdi recommends to use support brackets assembled to display’s back. An additional support will stiffen the whole structure and minimize the influence of external factors such as vibration. Figure 1 and Figure 2 below show examples of using support elements.

Figure 1. Example of using support brackets

For dimensions 3.5”, 4.3”, 5.0” and 7.0” the product with mounting frame version is available. Thanks to the four catches attached to the side, frame provides strong assembly to the surface by mounting element (like the screw, see Figure 3). The frames are specially designed to fit Riverdi products perfectly. The diameter of the mounting hole is 3.5mm.

Note1:The brightness of LCD panel could be changed by adjusting the AC component of VCOM.

Note2: STHL, STHR, OEH, L/R, CPH1~CPH3, STVD, STVU, OEV,CKV,U/D

Note: If LED is driven by high current, high ambient temperature & humidity condition. The life time of LED will be reduced. Operating life means brightness goes down to 50% initial brightness. Typical operating life time is estimated data.

Note 1. Contrast Ratio(CR) is defined mathematically as below, for more information see  Figure 4 .

Note 2. Surface luminance is the LCD surface from the surface with all pixels displaying white. For more information, see Figure 4 .

Note 3. The uniformity in surface luminance δ WHITE is determined by measuring luminance at each test position 1 through 5, and then dividing the maximum luminance of 5 points luminance by minimum luminance of 5 points luminance. For more information, see Figure 4 .

Note 4. Response time is the time required for the display to transition from white to black (Rise Time, Tr) and from black to white (Decay Time, Tf). For additional information see FIG 1. The test equipment is Autronic-Melchers’s ConoScope series.

Note 5. CIE (x, y) chromaticity, the x, y value is determined by measuring luminance at each test position 1 through 5, and then make average value.

Note 6. Viewing angle is the angle at which the contrast ratio is greater than 2. For TFT module the contrast ratio is greater than 10. The angles are determined for the horizontal or x axis and the vertical or y axis with respect to the z axis which is normal to the LCD surface. For more information see Figure 4.

Note 7. For viewing angle and response time testing, the testing data is based on Autronic-Melchers’s ConoScope series. Instruments for Contrast Ratio, Surface Luminance, Luminance Uniformity, CIE the test data is based on TOPCON’s BM-5 photo detector.

Note 8. For TFT module, Gray scale reverse occurs in the direction of panel viewing angle.

I: input, O:output, P:Power

Note 1. If LVDS input data is 6 bits, SELB must be set to High;
If LVDS input data is 8 bits, SELB must be set to Low.

Note 2. When CABC_EN = ”00”, CABC OFF.
When CABC_EN = “01”, user interface image.
When CABC_EN = “10”, still picture.
When CABC_EN = “11”, moving image.
When CABC off, don’t connect DIMO, else connect it to backlight.

Note 3. When L/R = “0”, set right to left scan direction.
When L/R = “1”, set left to right scan direction.
When U/D = “0”, set top to bottom scan direction.

DEVICE_MODE

This register is the device mode register, configure it to determine the current mode of the chip.

GEST_ID

This register describes the gesture of a valid touch.

TD_STATUS

This register is the Touch Data status register.

TOUCHn_XH(n:1-10)

This register describes MSB of the X coordinate of the nth touch point and the corresponding event flag.

TOUCHn_XL(n:1-10)

This register describes LSB of the X coordinate of the nth touch point.

TOUCHn_YH(n:1-10)

This register describes MSB of the Y coordinate of the nth touch point and corresponding touch ID.

TOUCHn_YL(n:1-10)

This register describes LSB of the Y coordinate of the nth touch point.

Standard acceptance/rejection criteria for TFT module.

Ambient conditions:

•       Temperature: 25±°C
•       Humidity: (60±10) %RH
•       Illumination: Single fluorescent lamp non-directive (300 to 700 lux)

Viewing distance:

35±5cm between inspector bare eye and LCD.

Viewing Angle:

U/D: 45°/45°, L/R 45°/45°

Note:
1) The test samples should be applied to only one test item.
2) Sample size for each test item is 5~10pcs
3) For Damp Proof Test, pure Water (Resistance>1MΩ) should be used.
4) In case of malfunction defect caused by ESD damage, if it would be recovered to normal state after resetting, it would be judged as a good part
5) EL evaluation should be expected from reliability test with humidity and temperature: some defects such as black spot/blemish can happen by natural chemical reaction with humidity and fluorescence EL has.
6) After the reliability test, the test samples should be inspected after 2 hours at least.
7) Functional test is OK. Missing segment, shorts, unclear segment, non display, display abnormally, liquid crystal leak are not allowed.
8) After testing, the current IDD should be within initial value ±20%
9) No low  temperature bubbles, end seal loose and fall, frame rainbow, ACF bubble growing are allowable in the appearance test
