Abstract
A displaceable display and a method for controlling an output of a display unit are disclosed. The display arrangement includes a circuit board, a display unit, a detector and a controller. The display unit communicates with the circuit board. The display unit is capable of rotating with respect to the circuit board and being placed in at least one particular orientation with respect to the circuit board. The detector automatically detects the particular orientation of the display unit with respect to the circuit board. The circuit board transmits signals to the controller and the controller routes the signals to output of the display unit as a function of the particular orientation.
Description
- The present invention relates generally to display arrangements, and, more specifically, to a displaceable display arrangement.
- A conventional display arrangement coupled to a sensor arrangement tend not to be flexible with respect to the placement of the display arrangement on a supporting structure (e.g., a sensor arrangement). An example of the conventional display arrangement coupled to the sensor arrangement (e.g., a pressure sensor) a pressure sensor, provides this combination mounted on a wall of a large tank of liquid.
- Once mounted, it is often impractical to change the orientation of the conventional display arrangement with respect to the sensor arrangement. In conventional display arrangements, changing the orientation of the conventional display arrangement might entail re-orienting circuit boards of the combination. Unfortunately, the re-orientation of circuit boards is not always possible under particular configurations, especially where space is very limited and the circuit boards and the circuitry therein are not resilient to displacement.
- Furthermore, because the conventional display arrangement includes a display unit that has a fully functional circuit board included therein, it may be inconvenient or not feasible to access and displace the circuit board of such display unit.
- The present invention provides a display arrangement which includes a circuit board, a display unit, a detector and a controller. The display unit communicates with the circuit board. The display unit is capable of rotating with respect to the circuit board and being placed in at least one particular orientation with respect to the circuit board. The detector automatically detects the particular orientation of the display unit. The circuit board transmits signals to the controller and the controller routes the signals to the display unit as a function of the particular orientation.
- The present invention also provides a method for controlling an output of a display unit. An orientation of the display unit with respect to a circuit board is automatically detected, and output signals from the circuit board are received. Then, the output signals are routed to the output of the display unit as a function of the orientation of the display unit.

- FIG. 1 illustrates an enlarged view of an embodiment of a
displaceable display arrangement 10 according to the present invention. Thedisplaceable display arrangement 10 includes adisplay unit 20 which is mountable on (or connectable) to acircuit board 30. - The
display unit 20 includes adisplay screen 40. Thedisplay screen 40 may be, for example, a liquid crystal display (LCD) or a light emitting diode (LED) display. In FIG. 1, thedisplay unit 20 is disposed on the circuit board in a first orientation A, which is the orientation for optimal viewing of the display screen along a line ofsight 45 of a user. FIG. 1 further illustrates that thedisplay unit 20 has a square shape; however, other shapes, such as, for example, regular polygons and circular shapes are within the scope of the present invention. - The
display screen 40 includes a first display field 50 (which may be, for example, variable) and, optionally, a second display field 60 (which may be, for example, non-changeable or fixed). Thefirst display field 50 may display, for example, symbols, alphanumeric characters or groups of alphanumeric characters which may be updated upon demand. In a preferred embodiment of the present invention, thedisplay unit 20 does not include any circuit board for controlling an output of thefirst display field 50. Thefirst display field 50 illustrated in FIG. 1 shows, as an example, a single alphanumeric character, e.g., a character “A”; however, this exemplary displayed character should not be construed as a limitation of the present invention. Indeed, one or more characters and/or symbols may be displayed on thedisplay screen 40. - In addition, the
second display field 60 may include, for example, symbols, alphanumeric characters or groups of alphanumeric characters. However, the symbols, alphanumeric characters or groups of alphanumeric characters are permanently burned, etched or printed on or within thedisplay screen 40. Thesecond display field 60 illustrated in FIG. 1 shows, for example, a word “DISPLAY”; however, this exemplary displayed word should not be construed as a limitation of the present invention. - Alternatively, the
second display field 60 can be a quasi-permanent display field in which at least one of several sets of symbols, alphanumeric characters or groups of alphanumeric characters can be selectively displayed by thedisplay screen 40. For example, if thesecond display field 60 is showing the units of measurements, then the selected symbols, alphanumeric characters or groups of alphanumeric characters selectively, may be either English or metric units. - Thus, the
first display field 50 may display changing numbers representing variable measurements while thesecond display field 60 can display the metric units of measurement. - The
circuit board 30 includes acircuit arrangement 70 and amounting location 80 for coupling thecircuit board 30 to thedisplay unit 20. In one embodiment according to the present invention, thecircuit arrangement 70 includes all of the circuitry for powering and controlling thedisplay unit 20. Themounting location 80 provides a coupling arrangement for electrically and mechanically connecting thedisplay unit 20 to thecircuit arrangement 70. FIG. 1 illustrates themounting location 80 having a square shape to approximately match the shape of thedisplay unit 20. Themounting location 80 may also have other shapes such as a circular shape or a regular-polygonal shape. Furthermore, themounting location 80 may have shapes that approximately match the shape of thedisplay unit 20 which is rotated at various angled intervals. - FIG. 2 illustrates an enlarged view of the
displaceable display arrangement 10 in which thedisplay unit 20 is in a second orientation B with respect to thedisplay unit 20. Thedisplay unit 20 shown in FIG. 2 has been rotated 90 degrees from the position of thedisplay unit 20 illustrated in FIG. 1, i.e., from the first orientation A. - This rotation B of the
display unit 20 is selected to allow the user of the arrangement to view the first and the second display fields 50, 60 regardless of the orientation of thecircuit board 30. - Despite the fact that the
display unit 20 is rotated 90 degrees with respect to thecircuit board 30, and particularly, with respect to thecircuit arrangement 70 and the mountinglocation 80, thefirst field display 50 of thedisplay unit 20 is oriented for optimal viewing of the user along the line ofsight 45 of the user. Furthermore, since thedisplay unit 20 has not been rotated with respect to the line ofsight 45, thesecond display field 60 is also oriented for optimal viewing along the line ofsight 45. - In operation, the
display unit 20 and thecircuit board 30 may be initially disposed in the first orientation A with thedisplay unit 20 being removably mounted at the mountinglocation 80 of thecircuit board 30. - Subsequently, the
display unit 20 may be oriented in the second orientation B, e.g., by lifting thedisplay unit 20 from the mountinglocation 80 of thecircuit board 30 and rotating thedisplay unit 20 90 degrees with respect to a particular axis of extension M of thecircuit board 30. Other orientations are also possible, depending on the user preferred position of thedisplay unit 20. Thedisplay unit 20 can then be re-mounted onto the mountinglocation 80. An axis of extension N of thedisplay unit 20 is then positioned 90 degrees with respect to the particular axis M of thecircuit board 30. - Although the
display screen 40 may be oriented for optimal viewing along the line ofsight 45 and along the axis N, input signals provided by thecircuit arrangement 70 of thecircuit board 30 to thedisplay unit 20 may require some rearrangement. - The circuit arrangement70 (or a control arrangement which is provided in communication with the circuit arrangement 70) ascertains that the
display unit 20 has been re-oriented with respect to thecircuit board 30. Furthermore, the circuit arrangement 70 (or the control arrangement) determines the extent of the re-orientation (e.g., determines an angle of rotation between the particular axis M and the axis N). Using the orientation information, the circuit arrangement 70 (or the control arrangement) can transmit input signals to thedisplay unit 20, by taking into account the current orientation of thedisplay unit 20 with respect to thecircuit board 30, and may generate an output from thedisplay unit 20 regarding its orientation. For example, thedisplay unit 20 displays the output for viewing along the line ofsight 45 and for easy viewing by the user (with the user being positioned approximately along the axis N and looking down on a front face of the display unit 20). - Although FIG. 2 illustrates the rotation of 90 degrees between the
display unit 20 and thecircuit board 30, the amount of rotation is merely exemplary. Thearrangement 10 of the present invention also allows thecircuit board 30 and thedisplay unit 20 to be rotated numerous degrees of rotation. - FIG. 3 shows a block diagram illustrating an embodiment of the
displaceable display arrangement 10 in an exemplarypressure sensor arrangement 90 according to the present invention. Thecircuit board 30 includes thecircuit arrangement 70 which, in turn, has amicroprocessor 100. It is also possible that the microprocessor is positioned externally from thecircuit arrangement 70 and is in communication therewith. Themicroprocessor 100 powers and controls thedisplay unit 20. Themicroprocessor 100 has at least one set of inputs from, for example, pressure sensors 110 and, optionally, fromother input devices 120. Themicroprocessor 100 has at least one set of outputs, for example, to thedisplay unit 20 and, optionally, toother output devices 130. - In operation, the
pressure sensor arrangement 90 may be mounted via a duct in a wall of a large tank filled with a liquid mixture. The pressure sensors 110 can, for example, be immersed in the liquid mixture on one side of the wall (i.e., an external side of the wall). Thecircuit board 30 can, for example, be on the other side of the wall. The sensors 110 generally sense the pressure of the liquid mixture. The pressure may be transmitted to thecircuit board 30 to generate a corresponding electrical signal, or the sensors 110 may include transmitters which generate corresponding electrical signals which are received by thecircuit board 30. Then, themicroprocessor 100 processes the electrical signals and converts them into actual or relative pressure values. The actual or relative pressure values are converted into operating and control signals which are displayed via thedisplay unit 20. - The
optional input devices 120 may be, for example, sensors for different parameters such as temperature, acidity, or oxygenation. Theinput devices 120 may include user interfaces such as for example, key pads, or values retrieved from memory storage devices. Theoutput devices 130 may be, for example, memory storage devices or other signal processing devices such as computers. - When the
pressure sensor arrangement 90 is mounted, for example, on the wall of the tank via the duct in the wall, thecircuit board 30 can, under certain circumstances, be immovably fixed to the wall of the tank. Thesensor arrangement 90 may be fixed in a position which would ordinarily rotate thedisplay unit 20 coupled thereto into a position in which it would be uncomfortable or inconvenient for the user to view the output on thedisplay unit 20. Thus, without the ability to re-orient thedisplay unit 20 with respect to thecircuit board 30, thedisplay unit 20 may not be easily readable by the user or awkwardly disposed. Thus, by re-orienting thedisplay unit 20 with respect to thecircuit board 30, the user may achieve optimal viewing of the output of thedisplay unit 20. - In the embodiment illustrated in FIG. 3, the
microprocessor 100 determines if thedisplay unit 20 has been re-oriented using outputs of thecircuit board 30. Accordingly, themicroprocessor 100 re-routes the operating instructions and control signals so that thefirst display field 50 of thedisplay screen 40 is correctly oriented for optimal viewing by the user. - FIGS. 4 and 5 illustrate a back view and a side view, respectively, of an embodiment of the
display screen 40 of thedisplay unit 20. Thedisplay screen 40 includes aliquid crystal element 140, for example, mounted on aglass plate 150. Theglass plate 150 includes metallizedcontacts 160 through which the circuit arrangement 70 (using, for example, the microprocessor 100) powers and controls theliquid crystal element 140. - FIGS. 6 and 7 illustrate a back view and a side view, respectively, of an embodiment of a
display screen housing 170 of thedisplay unit 20. Thedisplay screen housing 170 includes a recessedsection 180 and awindow 190. The recessedsection 180 has a particular shape and form for receiving and accommodating thedisplay screen 40 as shown in FIGS. 4 and 5. For example, thewindow 190 may have a circular shape. - FIG. 8 illustrates a back view of an embodiment of the
display unit 20 according to the present invention. Thedisplay unit 20 includes thedisplay screen 40, thedisplay screen housing 170, fourpads 200 and anelastic guide 210. - The
display screen 40, as shown in FIGS. 4 and 5, is placed in the recessedsection 180 of thedisplay screen housing 170, which is illustrated in FIGS. 6 and 7. The four pads are placed on top of the metallized contacts are which are maintained in place against inner walls of the recessedsection 180 by theelastic guide 210. Theelastic guide 210 is shaped, for example, to maintain the fourpads 200 in position by an elastic force. The fourpads 200 are soft and elastic, and enable thedisplay unit 20 to electrically communicate with thecircuit board 30. The fourpads 200 extend, at least in part, out of the recessedsection 180 to provide a cushioned contact with the mountinglocation 80 of thecircuit board 30 when thedisplay unit 20 is mounted on thecircuit board 30. - FIG. 9 illustrates an embodiment of the
pad 200 according to the present invention. Thepad 200, as shown, has a rectangular shape with three layers. Amiddle layer 220 is provided between two insulatinglayers 230. Themiddle layer 220 includes a plurality ofconductive channels 240. Theconductive channels 240 enable electrical communications between the metallizedcontacts 150 of thedisplay screen 40 and thecircuit arrangement 70 of thecircuit board 30. - FIGS. 10 and 11 illustrate a
coupling arrangement 250 for thedisplay unit 20. FIG. 10 shows a top view of thedisplay screen housing 170 with four sets ofnotches 260. - Each set of
notches 260 may include two notches, e.g., adecoupling notch 270 and acoupling notch 280. Thenotches external tool 290 illustrated in FIG. 12. Theexternal tool 290 has, for example, a Phillipsscrew driver tip 300 which fits, at least in part, into thenotches external tool 290 are also contemplated by the present invention. - FIG. 11 illustrates a side view of a section of the
coupling arrangement 250 for thedisplay unit 20 according to the present invention. Acoupling mechanism 310 is disposed across thenotches coupling mechanism 310 pivots around a pivot point 320. - The
display unit 20 is disposed, for example, on a top portion of thecircuit board 30, in particular, over the mountinglocation 80. Thedisplay unit 20 is coupled to thecircuit board 30 by inserting thetip 300 of theexternal tool 290 into thecoupling notch 280, such operation forces thecoupling mechanism 310 downward and clockwise around the pivot point 320. The displacement of the coupling mechanism results in ahook 330 engaging with either a bottom portion of the iscircuit board 30 or a recess adapted to accommodate thehook 330. The process is repeated for each of the remaining sets ofnotches 260. The engagement of thehook 330 also provides for the compression of the four pads 200 (shown in FIG. 8), thus ensuring a resilient contact between thecircuit board 30 and the metallizedcontacts 160 of thedisplay screen 40. To decouple thedisplay unit 20 from thecircuit board 30, thetip 300 of theexternal tool 290 is driven, at least in part, into thedecoupling notch 270. In response, thecoupling mechanism 310 is forced counter-clockwise around the pivot point 320, and thehook 330 releases either the bottom portion of thecircuit board 30 or the recess which is adapted to accommodate thehook 330. - FIG. 13 illustrates another embodiment of the
display screen 40 according to the present invention. The embodiment of thedisplay screen 40 shown in FIG. 13 is the same as thedisplay screen 40 illustrated in FIG. 4, except that two particular contacts of the metallizedcontacts 160 are interconnected to create ashort circuit 340. In operation, when thedisplay screen 40 is coupled to thecircuit board 30, thecircuit arrangement 70, or a control arrangement (which may or may not include the microprocessor 100) determines which two contacts of the metallizedcontacts 160 are interconnected, thereby creating between the metallizedcontacts 160 theshort circuit 340. Upon determining the location of theshort circuit 340, the circuit arrangement 70 (or the control arrangement) can ascertain the orientation of thedisplay unit 20 with respect to thecircuit board 30, in particular, with respect to thecircuit arrangement 70. After determining the orientation of thedisplay unit 20 with respect to thecircuit board 30, the circuit arrangement 70 (for example, via the microprocessor 100) may power and control thedisplay unit 20 so that the output of thedisplay screen 40 is oriented for the desired line ofsight 45 of the user. - FIGS.14-17 illustrates an embodiment of the
display arrangement 40 in which thecircuit arrangement 70 includes a liquid crystal display (LCD) driver 350. FIGS. 14-17 also illustrate the cooperation of the metallizedcontacts 160 of thedisplay screen 40 with thepins 360 of the LCD driver 350. In FIG. 14, thedisplay screen 40 has not been rotated with respect to the LCD driver 350. In FIG. 15, thedisplay screen 40 has been rotated 90 degrees with respect to the LCD driver 350. In FIG. 16, thedisplay screen 40 has been rotated 180 degrees with respect to the LCD driver 350. In FIG. 17, thedisplay screen 40 has been rotated 270 degrees with respect to the LCD driver 350. - As shown in FIGS.14-17, the LCD driver 350 controls 40 segments via pin locations SEG(00) through SEG(39). The LCD driver 350 also includes back-plane pin locations BPLm(n) where m and n are integers between 0 and 3. The
display screen 40 includes display-segment pin locations DS0 through DS36 and back-plane pin locations BPL0 through BPL3. Thedisplay screen 40 also includes display pin locations DP0 through DP3. - FIG. 18 illustrates a block diagram of an embodiment of the LCD driver350 according to the present invention. The LCD driver 350 includes a
controller 370, a 160-stage shift register 380, a 160-bit latch 390, a segment decoder 400 and a 40-output LCD segment driver 410. The 160-stage shift register has at least three input lines including a serial data line SERDATA, a load signal line LOAD and a serial clock signal line SERCLK. - Display data is serially input to the 160-stage shift register via the serial data line SERDATA. The 160-stage shift register is synchronized by a clock signal from the serial clock signal line SERCLK. Upon receipt of a LOAD signal from the load signal line LOAD, the 160-
stage shift register 380 is transferred to the 160-bit latch 390. The latched data is decoded by the segment decoder 400. A MODE signal on a control input line MODE is received by thecontroller 370 which controls the segment decoder 400. The MODE signal determines a mode selection, for example, either a straight connection when maintained low, or a special encode when maintained high. - From the segment decoder400, the data is output to the 40-output LCD segment driver 410 in four phases. FIG. 19 illustrates an example of a four-phase dynamic display operation according to the present invention, in which the output signal sequence is controlled by four back plane signals.
- The routing from the outputs of the
pins 360 of the LCD driver 350 to the proper metallizedcontacts 160 of thedisplay screen 40 depends upon, for example, how much thedisplay screen 40 has been rotated with respect to the LCD driver 350. Once the orientation of thedisplay screen 40 with respect to the LCD driver 350 has been ascertained, the re-routing of the outputs of the LCD driver 350 can be achieved via software, hardware or a combination thereof. - FIG. 19 illustrates an exemplary embodiment of routing (or firmware)
arrangement 420 according to the present invention. Therouting arrangement 420 includes fourmultiplexers - Reference is made to directions north N, south S, east E and west W, as defined and shown in FIGS.14-17. These directions remain constant with respect to the LCD driver 350 even when the
display screen 40 is rotated with respect to the LCD driver 350. Furthermore, thepins 360 of the LCD driver 350 will be specified below by referencing a particular side. Thus, pins 0 refer to the pins on the south side of the LCD driver 350;pins 1 refer to the pins on the east side of the LCD driver 350;pins 2 refer to the pins on the north side of the LCD driver 350; and pins 3 refer to the pins on the west side of the LCD driver 350. - To illustrate such correspondence, FIG. 15 shows that the
display screen 40 has been rotated 90 degrees clockwise with respect to the LCD driver 350, thepins 0 face the south side pins of thedisplay screen 40, in this case, pins DP1, DS09 through DS17, BPL1; thepins 1 face the east side pins of thedisplay screen 40, in this case, pins DP2, DS18 through DS26, BPL2; thepins 2 face the north side pins of thedisplay screen 40, in this case, pins DP3, DS27 through DS36, BPL3; and thepins 3 face the west side pins of thedisplay screen 40, in this case, pins DP0, DS0 through DS8, BPL0. FIGS. 14, 16 and 17 can be similarly described. - Referring to FIG. 19, the
routing arrangement 420 couples to thepins contacts 160 of thedisplay screen 40 as a function of the orientation of thedisplay screen 40 with respect to the LCD driver 350. The input to each of the fourmultiplexers pins multiplexers contacts 160 on a respective side of thedisplay screen 40, e.g., the metallizedcontacts 160 on the south side of thedisplay screen 40. Each of the fourmultiplexers - The select lines s1, s0 are defined as a function of the orientation of the
display screen 40 with respect to the LCD driver 350.
